The recent lessons learned from Shaw and PCA should really educate the decision-making process around Caissie (as well as guys like Alcantara, Long, and Ballesteros, to various extents). He's prone to Ks and has shown the need to make adjustments with each promotion. He's made them so far in AAA, which is great! He looks ready!
Except the reasonable expectation for him should be that he will fall flat on his face at the plate after being called up. Unlike Shaw or PCA, he's not a premium defender, so it will make things even worse by comparison.
For whatever reason, the gulf between AAA and the majors for hitters is even more pronounced now than it was even a decade ago. We expect the 2026 Cubs to be just as competitive as now; can they carry Caissie for 200-300 PAs while he figures things out, especially if he's manning a position like LF or 1B that should produce a lot of offense?
I like the idea of keeping him, but, in a way, he represents one of the best chances this team has to make the WS this season due to his trade value. I'm not saying trade him for anyone, but if it means getting someone like Gore? I'm all in favor.
