5-11/175, muscular w/+strength...RHH 2025 C/OF w/+aggression to every facet of game & +makeup/work ethic...never gets cheated, takes a healthy hack, looks to lift/drive balls deep top all fields, got some bat speed considering near no load, just pure strength, feel exit velo could improve with more of a load to, potential middle-of-the-order run producer...works his tail off behind plate, good blocker, very active, arm not his best tool, athletic enough & moves well in OF, LF may end up primary position...+makeup may be light, excellent work ethic & 4.0 GPA...get get for Simpson U where Kabayashi could be a big contributor as a freshman.
