Naoyuki Uwasawa: Rookie Year Struggles and Outlook

Using his rookie data, we consider whether Uwasawa can adapt going forward.

Uwasawa moved from Nippon-Ham to MLB in 2024 and struggled early, in part because he lacks a true velocity advantage.

His breaking ball quality isn't bad, but his mix needs reshaping against MLB hitters' elite contact skills.

He has retried via the minors — with the right adjustments, sticking in the majors remains realistic.

2026 is likely the pivotal year for his continued MLB career.
