This is interesting! Though I'll say the fact that the Marlins are the best in the league makes me a bit dubious. But I think it's notable that even if you play around with GameDay zones it stays true. This isn't just a backdoor to showing that PCA and (to a lesser extent) Swanson's helplessness against the bellybutton high fastball is dragging the team down.
It also made me curious about the Iowa bats, since that's a logical place to look to improving this for next year. It looks like this year at Iowa:
- Jonny Long swung and missed a little more, put the ball on the ground a lot more, but still continued to hit the hell out of the ball. Thumbs up overall
- Kevin Alcantara thrived. Again a higher GB rate but whiffs came way down and hard hit rate skyrocketed. This is probably instructive. Most likely the Cubs are one or two dead red fastball hitters short of ideal, but overcommitting to fixing this issue risks giving you a Miami Marlins' lineup
- Mo is weird. His hard hit and barrel numbers jumped, while his whiff rate fell, yet his xwOBA was mostly flat. I assume he's popping up or barrelling with little in between? Overall positive though
- Caissie got absolutely eaten alive by velocity. Looks like it happened last year too. That's...concerning
So the internal reinforcements should help here, but definitely feels like something that needs to be kept in mind when assembling the bench.
