They'd built their bullpen plans around three right-handed pitchers: flamethrower Julian Merryweather, coming off a 2023 season in which he'd gone from an unnoticed waiver claim to a relief ace; analytics darling Yency Almonte, part of the Michael Busch trade; and Héctor Neris, a free-agent reclamation project whom the team hoped would rediscover the swing-and-miss that made him a dominant closer in Houston. Within a month and a half, Merryweather and Almonte were sidelined by injuries from which they still haven't really recovered, and Neris was clearly a failed experiment. In desperation, Jed Hoyer scooped up former Cubs farmhand Tyson Miller, who was on the outside looking in for the Mariners at the time. Miller's funky delivery and command of a terrific cutting fastball/sweeper combination turned out to be more than enough to offset his lack of velocity, though, and he became one part of a rebuilt Chicago bullpen. Miller pitched 50 1/3 innings in 49 appearances for Chicago that year, with a 22.5% strikeout rate, a 5.3% walk rate, and a 2.15 ERA. Along with fellow scrapheap find Jorge López and developmental breakthrough Porter Hodge, Miller saved that bullpen—though it wasn't quite enough to save the season. Last spring, the crisis arrived even sooner. Ryan Pressly was a flop, just as Neris had been. It was Hodge's turn to get hurt and never be the same. Ryan Brasier and Eli Morgan, too, had been waylaid by arm trouble. The team had rousing successes in Caleb Thielbar and Brad Keller, but they were short on healthy arms and pitchers who could absorb innings to keep Craig Counsell from having to overuse his best relievers. Hoyer found salvation in Seattle again, this time purchasing the rights to Drew Pomeranz. The two-pitch southpaw pitched 57 times for Counsell, with a 2.17 ERA and similarly solid strikeout and walk numbers. He gave the team time to find the hierarchy that worked for them the rest of the year, headlined by Keller, emerging homegrown star Daniel Palencia, and trade deadline acquisition Andrew Kittredge—along with Pomeranz and Thielbar. Those are just a few examples of Hoyer finding improbable ways to assemble viable bullpens on the fly. Mark Leiter Jr., Rowan Wick and Scott Effross also number among his success stories. On the other hand, it can be too easy to forget all the acquisitions who didn't hurt the team as glaringly or cost as much to sign as Pressly, Neris, Almonte or Morgan, but who also didn't yield what the front office hoped for—guys like Nate Pearson, Michael Fulmer, and José Cuas. In some important degree, the Cubs' bullpen magic has been the product of good luck and/or good timing. Even having gotten it broadly right over the last three years doesn't guarantee that the team will do so again. That's a scary notion, because lo, they already need to do it again. Palencia, Hunter Harvey, and Phil Maton have already hit the injured list, along with lower-upside options Ethan Roberts and Hodge. Injuries to the starting rotation have drawn Colin Rea and Javier Assad into that duty and away from the pen, though Wednesday's return of Matthew Boyd put Assad in the pen again for now. On Thursday, the team might have suffered another loss, as Thielbar left in the ninth inning of the team's game against the Phillies with a hamstring problem. The relief pitching scaffolds Hoyer built this winter have already crumbled. He'll have to go out and find an arm outside the organization, and the sooner, the better. However, his track record only goes a short way in providing real confidence about the outcome of that addition. The Cubs need relief help, right away, but the odds of them nailing yet another such move feel lousy, The good news, of course, is that Ben Brown is settling into his new role gorgeously. Having failed in an extended audition as a starter last season and not having earned even a top-7 spot on the rotation depth chart this spring, Brown is now a reliever in full. He's taking to it marvelously. Brown's fastball is up a tick, sitting just under 97 MPH. His curveball, meanwhile, is as firm as ever, but with slightly more depth. After two years of trying to get the changeup right, he's leaning more into the two-seamer this season, creating the lane change he's long needed to keep right-handed batters off the two main pitches in his arsenal. As a result, he's running numbers similar to what Pomeranz and Miller gave the Cubs over the last two seasons, but in more volume. If the team stops needing him to give them multiple innings within games, there might even be another gear, but this version of him is already a viable stand-in for Palencia and Maton. With some luck, the team will get at least one of their top right-handed relievers back soon, and keep them healthy the rest of the way. To survive their current barrage of injuries, though, they need outside help, and that means that risk lies ahead. They've done some things right already. There are encouraging signs about the usefulness of homegrown lefty Riley Martin and minor-league signing Corbin Martin, each of whom are (for the moment) healthy. Brown is what they need him to be. With so many pitchers already hurt, though, what they have so far is necessary but not sufficient. View full article

Just that he doesn't think in numerical terms about it all. He's plenty smart enough to, and he accepts that kind of feedback, but he isn't consciously going, "The new rules make the zone smaller. I'm going to swing less often, because that's the best way to take advantage of this change." It's more like, he has his zone organized, spatially, and when he does lay off that high pitch and it's not called a strike, he's both getting reinforcement of his swing decisions and moving further ahead in the count, forcing pitchers to come into the meat of the zone, where he can do the real damage. It's a little more physical and a little less statistical than the way I presented it.

Image courtesy of © Matt Marton-Imagn Images Have you seen the new Peacock show "The Miniature Wife"? Yeah, me neither. It's baseball season. The NBA playoffs are here. My nephew played the lead in his high school's production of Anastasia last weekend, and I have a new niece and a new nephew to fawn over, and I really should clean out the garden beds now that it's finally warming up. And did I mention that it's baseball season? There's a lot going on! I feel a little (no pun intended) (ok, pun intended, don't pretend you didn't see that one coming) like I've seen the show, though, because I've been watching so much of this season's baseball. Elizabeth Banks plays a shrunken person in the show, but if she were a strike zone instead of a wife, the show would be exactly like an MLB game in 2026. I assume so, at least. You know what? Actually, I don't know enough about the show to make any further meaningful assumptions. Let's all agree to binge "The Miniature Wife" together in November. Until then, it's time to focus on The Miniature Strike Zone. This season brought the implementation of the ABS challenge system, and with it has come a smaller strike zone. The change actually began in 2025, when the league informed umpires they would be evaluated based on a smaller margin for error in advance of the onset of the computerized zone. Tightening tolerances at the edges and corners created a slightly smaller zone. This year, with the zone still called by humans but now actually, tangibly reinforced by computers, the effect has run in the same direction, but even more markedly. For several years, now, the league has trended toward filling up the strike zone more. Fastballs are harder and livelier than ever; pitchers have better command of their non-fastballs than ever; and fielders are better-positioned than ever. You have to pitch more carefully, because hitters are also more powerful and more focused on hitting for power than ever, but on balance, the league has found the incentives favor throwing more pitches in the zone, so that's what they've been doing. This year, that trend has been stopped cold. It's not that the league has stopped trying to fill up the zone, though. It's that the zone itself has gotten smaller. Hitters have noticed, too. The league's average swing rate is down. Twice as many batters have substantially reduced their swing rate so far this year (at least two percentage points lower than last year, with a qualifying number of plate appearances in each campaign) as have substantially increased it. Dansby Swanson isn't just participating in that trend; he's one of the foremost drivers of it. In fact, only two batters (Ceddanne Rafaela and Royce Lewis) have lowered their swing rates more than Swanson has in 2026. Last year, he swung at 50.3% of the pitches he saw. This spring, that number is down to 38.6%. He's being radically patient, in response to the shrinking of a zone he already understood well, but couldn't always cover. Though umpires aren't perfect (and neither batters nor catchers challenge often enough to make them so by correcting their mistakes), theoretically, the top of Swanson's strike zone now is about 38.52 inches above the ground. (I say "about", here, not because two places after the decimal is too few to have the precision right, but because we only have Swanson's reported height of 6 feet to work with; the league has his height down to the millimeter.) The bottom of his zone is now roughly 19.44 inches above the ground. The first thing you should notice is that that's only 19 inches from high to low. Traditionally, we've thought about the strike zone as being taller than that, even for batters around Swanson's height. When you picture the zone in your head, you probably think of a rectangle taller than it is wide, by a noticeable margin. Well, it's now more like a square. Because any pitch that touches even the edge of the zone is called a strike if challenged, we can say that Swanson's zone is now basically 22.8 inches (the 17-inch width of home plate, plus the diameter of a baseball on each side) by 24.9 inches (19.1 inches, or a hair less, plus the same ball's width high and low). That's a lot like a square. It leaves Swanson needing to cover as much as he always has from east to west, but less from north to south. He's taking full advantage of that, too. I looked at pitches in each of the zones about two balls' width wide along the top and bottom of Swanson's newly concretized zone, and at the pitches in between those railings. Swanson is swinging less in each of the three locales, but especially down at the bottom of the zone—and he's benefiting from the new shape of his zone, especially at the top. 2025 Pitch Height Swing Rate Swings RV/100 Take Rate Takes RV/100 1.4-1.9 ft. 48.0 -5.8 52.0 1.2 1.9-3.4 ft. 64.1 -1.3 35.9 -0.2 3.4-3.9 ft. 63.8 -1.7 36.2 0.0 2026 Pitch Height Swing Rate Swings RV/100 Take Rate Takes RV/100 1.4-1.9 ft. 25.7 0.0 74.3 1.0 1.9-3.4 ft. 54.1 -2.2 45.9 1.1 3.4-3.9 ft. 50.0 -13.6 50.0 2.6 At his best, Swanson is a guy who wants to see the ball up and attack it there. He has a relatively steep swing for a high-ball hitter, with plenty of tilt in his bat path and a combination of contact point and attack angle that says he's always trying to launch the ball. He's a low-average, high-power hitter. However, he often gets himself in trouble because (in the process of trying to see the ball up) he chases too many pitches above the zone. His zone now stops much lower than it used to, which makes it easier for him to be more selective up there, even as he maintains the aggressive mindset of seeing it up to make the high-value contact he seeks. Setting the pitches at which he didn't swing along the top of his new zone side-by-side really shows how the altered zone is making his life easier. He's gotten a handful of calls, already, on pitches up and in that would have been—were—strikes last year. That takes a lot of pressure off him, as he looks for that belt-high pitch he can belt. Along the bottom rail of the zone, it's harder to see the clear benefit in terms of extra calls, but Swanson can afford to let a few more called strikes accumulate there than he used to be able to. Not having to sweat the top of the zone makes the bottom edge of the zone less important. He's ahead in counts more often. He can be more selective, then aggressive on the pitches that enter his happy zone. I've talked to Dansby Swanson a couple of times. Based on those conversations, I don't think this is quite how he's thinking about the changes to his approach this season. Whether you conceptualize it this way or not, though, this is what's happening. Swanson doesn't have exceptionally good feel for the barrel, like teammates Nico Hoerner and Alex Bregman do. He's still going to swing and miss quite a bit, and he's never likely to run a very high BABIP. Some younger versions of him could do that, but this one can't. Instead, Swanson's upside at the plate lies in his ability to hit the ball over the wall, without losing contact with all of his other skills. He has a well-engineered power hitter's swing, even though he's a fairly fast, glove-first shortstop and has never had elite bat speed. With this change in the league's rules and the shape of the strike zone, the best version of Swanson can emerge. It's just not the version you might have thought would be the best form of him. Right now, Swanson is batting .187/.337/.400. He probably won't finish the season with such an extreme-looking line, but yes: Dansby Swanson really is a little bit like Rob Deer and Carlos Peña. Those guys swung for the fences, and they knew they would strike out a lot. By also walking a lot, though, they kept themselves viable even when the ball wasn't clearing the fences. When it did, they became star-caliber sluggers. A smaller zone means Swanson can focus that unique swing on pitches in a smaller space, and he's been very smart about doing so. If he continues to, he can still produce the 25-homer power that first made him a star in Atlanta, and he can walk enough to be a plus OBP guy, too. It might come with an ugly batting average, because the called strikes and the whiffs will add up to a rising strikeout rate, but that might be the best version of this late-career Swanson. I'm not sure we want ABS to turn many players into peak Rob Deer. It might be a sign of something troubling, just as "The Miniature Wife" leaves me with an inarticulable unease. There might need to be tweaks to this new, robot-influenced zone. For now, though, it's allowed Swanson to draw 18 walks and hit 5 homers in just 23 games. Well-utilized by a savvy veteran, the system is turning out to be a boon to the patient power hitter. View full article

Image courtesy of © Kamil Krzaczynski-Imagn Images If you want to play with some selective endpoints, you can end up pretty deeply impressed by Nico Hoerner these days. He blasted his fourth home run of the season in the Cubs' seventh straight win on Tuesday night, and since last August 24—I did warn you the endpoints would be selective—he's batting .327/.384/.505 in 245 regular-season plate appearances. Kick in a tremendous postseason showing, you're up to .339/.388/.510 in 278 trips to the dish. He has 26 extra-base hits in that span. He's hit 8 homers. The topic of Hoerner's power potential has been an almost constant point of discussion over the last few years. I wrote about the very low apparent ceiling for it in May 2024, based on his inability to reach high-end exit velocities and the way defenses have evolved to cut off balls better as they head for the gaps. I also wrote about the way Hoerner's hands work (relative to one another and to the bat) in the context of his bat control and contact skills in early 2023, which included a discussion of how that style of swing consciously trades power for contact and opposite-field value. By last September, however, it was clear Hoerner had made some adjustments. He'd locked into a new approach that, without sacrificing the ability to go the other way or to make good swing decisions and draw the occasional walk, produced many more line drives to left field. It boosted his batting average more than his isolated power, but once you're pulling the ball in the air a bit more, power increases almost on its own. Back at the beginning of spring training, Randy Holt wrote about the questions posed by Hoerner's late-season power surge, and tried to assess the likelihood that it would carry over. About a week into the season, I followed up with a partial answer, based on some changes Hoerner brought into this campaign: a slightly wider stance and a shorter stride, giving him more early stability and the capacity to hit the ball hard down the lines, rather than toward center field. Now, it's time to synthesize all that into a firm answer to an increasingly pressing question: Is Hoerner a full-fledged power hitter now? He is, and he isn't. Oh, man. That's not the satisfying answer we all wanted, is it? Ok, let me try again. Yes, Hoerner has found the best way to unlock power in his game. Those adjustments we saw last year did quite a bit of the work; his stance adjustments this spring have completed the job. Here's a side-by-side comparison of the batted balls over 88 MPH in exit velocity Hoerner produced from the start of last season through August 15, and the ones hit at least that hard that he's produced since, by launch angle. To spot the differences, note that he's not hitting balls hard into the ground or popping them up. Next, note the right edge of the curve described by the chart. He's hitting it slightly harder, at the high end, and he's clustering his hard contact in a productive launch-angle band. Now, here's his spray chart heatmap for those same batted balls, with the same dividing dateline. Fewer of these well-hit balls are going to right field. More are going deeper into left, left-center, and center. That larger, brighter blob blooming in shallower left field on the right is the surest sign of his overall progress; those are the balls his approach is now focused on generating. He'll always be better at producing hard-hit singles to left field than at slugging; it's what he does best. His bat speed is below-average, and that's not going to change. He's not going to hit 30 home runs; he very well might never even hit 20. A couple years ago, though, it looked like Horner was destined to hit anywhere from .280 to .310 and slug anywhere from .350 to .390. Now, I think, you can safely bump the latter number up to .420, and maybe even .450. He's gotten a bit of good fortune over these 280ish plate appearances; he's hit a couple of wall-scrapers that just barely carried out of the park. However, Hoerner's power surge is real. Why? Because he's dedicated himself to the pulled line drive. Lock in on that outcome, and the rest of what's needed falls into place. Most line-drive hitters like to hit it right back where it came from, and that's what Hoerner used to do, too. The guys with low bat speed who still hit for good power (including recent ex-Cubs Cody Bellinger and Isaac Paredes) aren't line-drive guys; they focus on pulling fly balls. The pulled line drive is not a popular approach, because it takes a special kind of hitter—and a particular set of constraints eliminating the chances of being other ones—to execute it. Hoerner is that special a hitter, though, and as he's embraced that, he's become more dangerous, in multiple facets. He's hit four home runs this year. Could he hit 10 or 12 more, before the year is out, without trading in the other things he's doing well? At long last, that answer is "yes". It might not make him a full-fledged MVP candidate, but this power boost does make Hoerner a legitimate All-Star, and it's already making the contract extension he and the team signed feel like a huge win for the Cubs.

Image courtesy of © David Richard-Imagn Images Pete Crow-Armstrong is the best defensive center fielder in baseball. As recently as last season, there was at least a modicum of debate about that—Ceddanne Rafaela of the Red Sox won the prestigious Fielding Bible Award for center field, and might even have deserved it. Now, though, Crow-Armstrong is leaving even Rafaela behind, and doing things in outfield defense that are barely even possible. On plays Statcast rates as 2 Stars or higher on its difficulty scale (i.e., plays where the chance of the ball being caught was under 90% but higher than 0%, based on the model's estimates using fielder location data and the hang time of the batted ball), Crow-Armstrong is 9-for-12 so far. That's a sensational 75% success rate, close to the 77.5% rate he put up on such plays last year. No other player was higher than 73.5% last season, so if he keeps this up, he's got a good chance to pace the league in that regard again. For one thing, though, that underrates him. Crow-Armstrong has one actual missed opportunity to make a catch this season. You probably remember it. In the Angels series in the first week of the campaign, Crow-Armstrong misplayed a sinking liner by Jeimer Candelario into a double. At worst, he should have stopped it and held Candelario to a single, but the ball was catchable. That was a mistake; even the best of us make one. Here's one of the other two balls rated as catchable (although the Catch Probability was just 5%) by Statcast. UHY2YTlfWGw0TUFRPT1fQmxCWlhRRUVCUWNBV1ZaVVVRQUhVRk5mQUFNRUJRSUFCVkVNQlFZQkNRUlFCZ1ZW.mp4 The model does try to account for the presence of the outfield wall, which is why the Catch Probability on this one was so low, but let's be real: the chance of making that catch is 0.0%, for anyone. Crow-Armstrong got a good jump and a fine read, but if he'd kept running fast enough to catch that ball, he'd have dislodged his shoulder (and perhaps an internal organ or two) in the subsequent collision with the wall. It's fine; other players are also having 5% plays counted against them when the real chance was none. But it's important to me that you know about this dynamic in defensive metrics. Here's the other play the system says he had a 5% chance to make, but missed. R0JyUVlfWGw0TUFRPT1fQkFGUlZWVUJVUVVBQ1ZvRFh3QUhWUU5YQUZrR1ZBY0FBMUlCQVZJR0FRWlFVZ29B.mp4 Once again, Crow-Armstrong slows—even stops—shy of the wall to play this ball. It looks less makeable than it might have looked if he'd been chasing down a would-be walkoff hit with two outs; maybe there's a universe in which a player never breaks stride, gets the right footing as they plant their foot in the wall (no time to flatten the angle of body to wall and glide up unassisted) and snares this ball, but it would be the catch of the century. It'd also risk a broken wrist, or ribs. The real catch probability (lower-case letters, since my model is not official) on this is 0.001%. Meanwhile, on several plays since the start of 2025, Crow-Armstrong has seemed to do the scarcely possible. He runs underneath high flies very well, but lots of fast players can do that. Byron Buxton, of the Twins, is excellent at using his speed to make up for slow breaks and at adjusting his body when needed to make a tough catch. Crow-Armstrong, though, takes away a stunning number of singles and doubles on line drives, by breaking exceptionally quickly and accelerating both faster and more relentlessly than any other outfielder in pursuit of a ball daring to seek purchase on the outfield grass. It's not the 120-foot runs on high drives that make Crow-Armstrong extraordinary; it's the plays like this one. NHlLcTZfWGw0TUFRPT1fVlFGV0JRVlhBd01BQUZKV1ZnQUhCUUpTQUFNQ1ZBQUFBVlVBQ0FkVUExQlJDRlFF (1).mp4 Statcast's Outfield Jump leaderboard tells a fascinating story about Crow-Armstrong's excellence. It grades players on the amount of ground they cover (in any direction) in the first 1.5 seconds after contact (Reaction); and in the next 1.5 seconds (Burst); and on the ground they gain or lose, relative to average fielders, via the efficiency of their routes to the ball (Route). It gives each of these in feet above average, and then gives a total—both relative to average, and raw. This season, Crow-Armstrong sits atop that Jump leaderboard. He gains 5.2 feet of ground across the three components, relative to the average outfielder, with a good (+1.8 feet) initial reaction but an otherworldly (+3.2 feet) burst in that secondary moment of pursuit. He's also more efficient in his routes than the average outfielder—and, again, here we risk underrating him. The more a player moves in that 3-second window, the more likely they are to waste at least a little bit of that movement. That's not a new idea, or even a bad thing; it's part of the conscious tradeoff outfielders make all the time. However, Crow-Armstrong doesn't lose efficiency to his remarkably quick response on fly balls. He shoots himself at the ball's landing spot like he's a missile-defense system, and he never misses. That 5.2 feet of ground covered relative to the average is impressive, but barely beats out Chandler Simpson and Jacob Young (the dots breaking the scale, off the right and lower edges of the graph above, respectively, with their incredibly fast but noisy starts after balls) to top the leaderboard. The raw number of territory Crow-Armstrong covers in that 3-second window, though, is the more astonishing one: 40.1 feet. That's not a number anyone else in the league is terribly close to. Second on the list is Simpson, who plays left field instead of center and only covers 38.6 feet. In fact, going back to the dawn of this tracking of outfielders in 2016, no one has covered 40 feet in those 3 seconds over a full season, or even done so in a partial campaign as an overzealous rookie. Crow-Armstrong is stretching the boundaries of the possible. He's a seaplane, in this way, flying just above a rising tide. In 2016, the median figure for ground covered in that window was 32.5 feet, and it stayed fairly flat through 2021 (32.6 feet). Since then, though, teams have accelerated their move toward younger, faster, better-instructed outfielders. The median ground covered in those 3 seconds over the last four seasons (and so far this year) go like this: 2022: 33.0 ft. 2023: 33.0 2024: 33.4 2025: 33.4 2026: 34.1 The sample for this year is still small, and the number is likely to come down a bit. Even so, the trend is clear. It's harder than ever to be 5 feet better at chasing after a fly ball than your peers in the big leagues, because those peers are getting better by the minute. Last summer, Isaac Collins of the Brewers became an Outfield Jump star by taking the practice of timing a hop to put oneself in the air when a pitch passed through the hitting zone from the infield dirt to his place in the outfield. A handful of players around the league now emulate Collins, making the outfield a more explosive, reactive area of the field than it was even a few years ago. To be a plus center fielder, you have to be able to cover at least 12 yards in 3 seconds, and (of course) you have to move in the right direction to flag down the ball every time. Crow-Armstrong is breaking the scale. He might not keep his average ground covered over 40 feet all season, and even if he does, someone else might come along and do it soon, too. The tide is rising. Somehow, though, even at a moment when outfield defense is getting much better, Crow-Armstrong is widening the gap between himself and the rest of the group. He catches everything; he catches some things that don't even register at remotely catchable. He's also brilliant at playing balls off the wall, charging ground-ball singles, and setting up under fly balls to get off the best possible throw. He can change a game with his defense in center field in a way no other player in the league can, because he's taken his game to a new level over the last year. It's not a matter of raw talent, though he's always had the tools he needed out there. It's about the way he's shaved all the rough edges off his game, until he stands well clear of a pack that leaves much less room for clearance than it used to. View full article

Image courtesy of © Eric Hartline-Imagn Images It's about to get a little nutty at Wrigley Field. The Cubs have managed to win four games in a row this week, flipping the narrative that had begun to surround a rocky start to the season. However, even as they've done so, they've been further depleted by injury. Matthew Boyd and Cade Horton have already been sidelined for a fortnight. One by one, though, they've also lost a number of key relievers: Phil Maton, Hunter Harvey, Ethan Roberts, and Daniel Palencia. That was after starting the season down Jordan Wicks and Porter Hodge, the latter of whom will miss the entire season after undergoing elbow surgery. At Triple-A Iowa, starter Jaxon Wiggins and reliever Gavin Hollowell have also been sidelined. As a result, the team already has several pitchers in the mix to whom they were hoping not to turn until summer. The latest addition, righty Corbin Martin, was with the team on a minor-league deal and joins the 40-man roster at the expense of Horton, who was transferred to the 60-day injured list to make room. Now, however, Martin can't be optioned back to the minors without being exposed to waivers. The team didn't want to recall him this soon, since that makes it much more likely that they'll lose him amid a roster crunch sometime soon. They had little choice, though. Thus, starter Javier Assad takes the ball Sunday, with a simple task: eat some innings. The Cubs' bullpen has just four (Jacob Webb, Caleb Thielbar, Hoby Milner and Ben Brown) of the eight members with whom they began the season. They're missing their top three right-handed options, and Brown (who became the de facto righty relief ace when Palencia went down) threw 38 pitches Saturday to secure their win over New York. Webb's combination of recent usage and wavering effectiveness will make Craig Counsell unlikely to turn to him with much enthusiasm in the late innings. Other than Thielbar and Milner, the team has no one fresh whom you want trying to hold a lead Sunday. Pitcher TUE WED THU FRI SAT TOT Brown, B 0 17 0 0 38 55 Webb, J 15 0 0 25 0 40 Thielbar 18 0 0 0 14 32 Milner 0 10 0 10 0 20 Little 0 19 0 0 0 19 Martin, R. 6 0 0 12 0 18 Rolison 11 0 0 0 0 11 Martin, C. 0 0 0 0 0 0 Assad himself is the team's seventh starting pitching option. He'll be asked, however, to pitch more like a No. 3: soak up innings and keep the team in the game. As long as he can do so, Counsell can piece together the final three-plus innings without overusing Ryan Rolison or Corbin Martin. Martin (the righty, not to be confused with the younger, optionable, left-handed Riley Martin) showed impressive stuff in his brief time with Iowa. His cut-ride fastball and knuckle-curve make a fascinating pair, and though he's thrown them just a few times, his sinker and changeup show startling amounts of arm-side run coming from his arm slot and branching from his main arsenal. That only makes it more important that the team not ask him to throw 45 pitches to get them six or seven outs. With Palencia and Harvey, especially, likely to be out for a while, the team badly needs right-handed relief depth, and Martin looks capable of being a solid middle reliever. Losing him before the end of April would put them at real risk of bullpen collapse. Counsell needs Assad to get him into the sixth inning Sunday, so he can mix and match and keep the pitch counts on each of the relievers he uses low. A lefty-heavy bullpen is a small problem. One running out of options altogether is a larger one, and it's a problem the team is on the cusp of running into at full speed, early in a long season. For a little while, every pitching appearance will be higher-leverage than it seems, because the team will have a need that reaches beyond that day: for the pitcher to come through the outing healthy, and for them to get the number of outs Counsell is asking for, so they don't stretch a thin staff past its breaking point.

The Cubs signed Carons Kelly in late 2024 to accommodate their move toward that very model. With Miguel Amaya establishing himself as (they hoped) the catcher of the present and future, Chicago looked to Kelly to provide stability and keep Amaya's workload relatively low, given his long history of injury trouble. To whatever extent the goal was to keep Amaya healthy, the plan failed. The younger backstop went down with an oblique strain in May, then came back and immediately suffered an ankle sprain in August. Amaya is still dealing with the effects of those injuries, and his track record says he might never be able to carry even an 80-game burden at catcher. Fortunately, though, the Cubs got more than they could reasonably have hoped for from Kelly. A stance and stride adjustment last spring helped Kelly get off to a blazing start at the plate. He struggled after Amaya went down, as his own workload suddenly spiked, but he remained a solid defensive backstop and manager of the game plan on the field. He wasn't a zero in the lineup, either; he just lost the thunder that he showed early in the campaign. Maybe that will happen again this season. The Cubs will be similarly out of good complementary options if Amaya gets hurt again, so the risk that Kelly ends up overloaded remains real. So far, though, he's batting a stellar .333/.455/.467, in 55 plate appearances. Over the last two seasons, he was not only superficially usable at catcher, but genuinely above-average at the plate, according to Baseball Prospectus's DRC+. He ran a 106 in his 2024 season, divided between the Detroit Tigers and Texas. In 2025, that figure held firm, at 104. This season, that figure is up to 118. He's been a weapon in a lineup that has needed him, as some of the players on whom the team expected to rely more heavily have gotten off to slow starts. Shortening his stride unlocked some power for Kelly, but the bulk of his changes came in 2024, before the Cubs got ahold of him. He got more aggressive in the strike zone, without chasing more, and he made more contact on those in-zone swings, to boot. He's held onto those improvements in his first year-plus with the Cubs, taking his offensive game to a new level. Kelly has always had a good eye at the plate. His 10.1% walk rate since the start of 2024 is the same as the one he posted from 2021-23. His strikeout rate has come down, though, from 21.4% to 18.1%, even as he's hit the ball harder. Now that we have bat-tracking data, it's fairly easy to see just how well Kelly's hand-eye coordination serves him. It's not just about making contact; he's squared the ball up on over 28% of his swings since the start of 2024. (The definition of squaring a ball up, for these purposes, is getting at least 80% of the possible exit velocity out of a given swing, based on the velocity of the incoming pitch and the speed of the swing.) This year, although the sample is far too small to assume it will hold, that number is over 38%. The league averages just under 26%. Kelly's bat speed is nothing special, but because he consistently hits it solidly, he doesn't need that lightning-fast rotation. As he's come to understand that about himself, he's gotten better at making good swing decisions and putting the ball in play. He's also been a star behind the plate. Last season, he excelled at blocking pitches in the dirt and preventing runners from advancing on them. He doesn't have an especially strong arm, but as is true of his lack of plus bat speed, he makes up for deficient talent with a surfeit of skill; he's one of the most accurate throwers in the game. He's a slightly below-average pitch framer, but this season, he's found a way to overcome that—and then some. Kelly has challenged nine called balls behind the plate this year, and gotten seven calls overturned. Statcast's model gives him 13 expected challenges, meaning there were some called balls (because he's not a great framer, especially along the lateral edges and at the top of the zone) he could plausibly have also challenged. However, the same model only suggests he should have won 7 of those challenges, so he's merely saved four expected confirmations (and four lost challenges for the Cubs) by being judicious. When hitters have challenged calls against Kelly, meanwhile, they've paid a dear price. Opposing batters are just 3-for-12 when challenging called strikes with Kelly catching this season. In one knot at the very bottom of the zone, he's induced five bad challenges by hitters. The Pirates wasted their challenges as a team on Sunday by challenging two near-identical pitches on which Kelly caught the ball somewhat snatchily, but which turned out to be legitimate strikes. Here's one of them, right away in the first inning: NnlNNzNfWGw0TUFRPT1fVWxCUVZWUlJVRkVBRGdjS1VRQUhDQVJXQUZoUVV3TUFCQVlNQXdSUUFBWUhCQW9B.mp4 And here's the other, in the seventh, just before the Cubs got some momentum and came back to win the game. NnlNNzNfVjBZQUhRPT1fVkFCVEJnRUVYd0VBWEZJQ0FnQUhDUUJTQUFCV1dsa0FWd2NIVVFzQUJGRlhVVkJm.mp4 It might look inelegant, but this style of framing works, and this year, it's become even more valuable than it was in the past. When Kelly catches a ball like that and the umpire makes the right call, there's still one party left who might be fooled: the poor hitter. After what they felt was an especially good take, watching the ball almost into the mitt, many hitters feel overconfident about their own zone judgment, especially when a catcher moves their mitt in an obvious way. Coaxing batters into bad challenges that cost their team the right to appeal decisions later in games is one new way catchers can create value under the ABS system, and lo, Kelly is doing it. He'll be most productive if the team continues to use Amaya as close to half the time as possible. Even if that does continue, he won't have an OPS near 1.000 all season. Kelly has made real and tangible improvements, though, and he's one of those players whose makeup and a key adjustment or two allows them to enjoy a later prime than others. You'll never hear him talked about as an All-Star, let alone an MVP candidate, because constraints on volume make him more effective. Like the 6th Man of the Year in the NBA or the Relief Pitcher Award coming to the BBWAA awards suite this season, though, an award for players who provide value by giving a team length, strength and depth while also playing at a near-elite level during their limited time on the field might ought to exist. If it did, Kelly would be a candidate for it. He's been that good since joining the Cubs, and he has a chance to be even better in 2026 than he was in 2025. View full article
