OSU trailing 2-6.

I have a question about something that happened early in the game.

The Vandy batter claimed the ball hit him on the wrist during his check swing.  In my opinion, his wrist was in the strike zone so it shouldn’t even matter - however; I don’t know the actual rule.  I couldn’t see contact on the many replays & I guess the umpires didn’t either.  I don’t know why it was reviewed.  If you lean into the strike zone & get hit - aren’t you out?
