Scouting Roch Cholowsky: Most Complete College SS In A Decade?

In the coming months, Baseball America draft expert Carlos Collazo will be leading a new offseason scouting series in which he’ll be examining some of the top players in the 2026 draft class. We’ll be getting into the weeds with video, data and reporting on key prospects to know as we prepare for the upcoming spring season.

First up? None other than the top player on our draft board, UCLA shortstop Roch Cholowsky.
