Mesa is a hold — league-average bat, nothing pulling either way.

His expected wOBA is .311, essentially league average, and his actual wOBA of .317 tracks right with it. There is no gap between what he has done and what his contact says he should have done, so no luck story is hiding in the line. His exit velocity and hard-hit rate are right at league, and his strikeout and walk rates are both slightly better than average. The one thing worth flagging is the swinging-strike rate at 13.9%, against a league average of 11%, and the chase rate at 35.5%, well above league. His expected wOBA has been stepping down across the sample, which is mild reason not to expect a leap. Nothing here is unstable enough to buy or sell. Hold.
