The reality of pitching prospects is that for every guy on the rise (like Porter Hodge or Hunter Bigge), you're probably able to find two or three who went the opposite way. Due to the stress put on pitchers and the amount of variance that is possible, pitchers come and go freely, often, and unpredictably. This year has been no different, with a handful of Cub prospects who haven't had the kind of year you'd have hoped for at the outset.
Caleb Kilian, SP/RP, Iowa Cubs (Triple-A)
Kilian isn't really a "prospect", at this point, but he's also not a major-league player, or a consistent... anything, right now, so I'm going to include him here. It's been rough sailing for a while for him--really, since he came up and made his MLB debut. Working through issues with generating in-zone whiffs, then control issues, the hope was that the big righty would figure it out this year in Iowa and maybe be a bullpen arm. Instead, Kilian got hurt and has missed the entire year.
At the age of 26, being rostered on the 40-man, this is the kind of season he couldn't have to keep his MLB future alight. The good news for KIlian is that, reportedly, he's been hitting near 100 mph on his rehab assignment, and maybe (just maybe) a switch to the pen can unlock something. I still fear that there's no chase pitch, even if he's throwing insanely hard. He's struggled to find any sort of breaking ball that induces strikeouts and chases, with a failed spike-curve and changeup in his wake.
Kohl Franklin, SP, Iowa Cubs (Triple-A)
My heart hurts having to put Franklin on this list, as I've been a big fan of him since his draft year. Franklin has always had almost everything you want in a pitcher: He had the size, he had the stuff, he had the look. He just never had the health or the control (two major parts of being a quality pitcher). Entering 2024, it was a big "make-or-break" year for the righty, as he was 24 and starting to enter the range where you'd have to move on from him if he couldn't put it together. Through his first six innings on the season, Franklin looked great; striking out five, walking none, and even earning a promotion after one start! Then... Tommy John.
Franklin will miss the entire 2024 season, and likely most of 2025, rehabbing and getting his strength back. That means he'll be almost 26 years old when we see him next. Now, that's not the complete end of him. Bigge made his debut at 26, to a chorus of cheers. But Franklin will have used up most of his prospect slack by then, and may never really be a starter. I'm bummed out. There was a truly good pitcher somewhere in Franklin. It's almost assuredly never going to be found.
Brody McCullough, SP, Tennessee Smokies (Double-A)
This one feels a bit harsh, because when he was pitching, he looked really good again, but his season has also been derailed by injuries. Much like the aforementioned Franklin, his age puts him in a weird place as a prospect. The good news is that McCullough had done enough to get promoted to Tennessee; looked great in his debut with the Smokies; and was looking like he might have been a real find as a 10th-round pick.
The bad news is that the 24-year-old has logged just 14 innings on the season, and is just nine months younger than Franklin. Given all that, if we're being fair, he belongs on this list. I don't think it's really his fault. Pitchers do this. They get hurt.
We don't really know what the extent of his most recent injury is, only that he hasn't taken the mound since May 10. But considering there isn't news of him throwing or rehabbing out there, it's safe to say that his return isn't imminent, either. The hope is that it's not arm-related, and that McCullough can still get two months or so of action in Double-A for the season, but as of now, he's trending the wrong way--despite the impressive results when he's on the mound. A healthy turnaround could make this placement look bad in the future, and I'd happily own it if he can look more like the healthy guy we've seen at times.
Drew Gray, SP, South Bend (High-A)
When the Cubs traded Jackson Ferris this offseason, Drew Gray became the de facto top lefty in the Cubs' system. With strong draft pedigree and stuff, the lefty was considered to be a potential breakout candidate, assuming his control came around. Considering he's on this list and not the other one, you can figure out quickly that the control didn't come around. Gray has walked more hitters than he's struck out this season, and has walked three or more hitters in his last eight starts. There's simply no feel for his mechanics right now. The positive is that he's still just 21 years old and left-handed; he's going to get more chances. And while this latest run is terrible, the handful of starts before that were more encouraging (though still problematic, with a 20% walk rate in those 19 innings).
Luis Devers, SP, South Bend (High-A)
Coming off his MiLB Pitcher of the Year Award in 2022, Devers looked like he might have a future in the Cubs system. There were always issues in his profile: Devers only really had one plus offering (his changeup) and everything else was fairly middling. Sadly, Devers has not been able to use his one good offering to overcome his shortcomings, and coupled with injury and rehab, the prospect light on Devers is very dim right now.
Back in South Bend, where he won his award in 2022, the 2024 season has been far less kind. In under 30 innings, Devers has been shelled when he's thrown strikes, sporting an ERA north of 7, and when he's not throwing strikes, has walked almost 15% of the hitters he's faced. At the age of 24, it's looking unlikely that Devers is going to have enough juice to be an MLB arm down the road. Further complicating things is that his profile just doesn't look appealing as a reliever, either. Devers is a cautionary tale of how numbers at lower levels can be deceiving at times, hiding major prospect red flags under the surface.
This is why you can never stop stockpiling young talent. it's why, even with one of the most highly-rate farm systems in baseball, the team needs to enter the second half with a focus on bolstering it. Detours are more numerous than direct routes where pitching development is concerned.
