He's going to be on ESPN (and equivalent) every time he does something off-beat. The glare is fine, but slamming the helmet and sticking his finger in the umpires face just leads to more trouble. He doesn't need the trouble, or to gain a reputation as a bush-leaguer.
He needs to learn to hit better pitching, and to keep his head in the game.
Incidentally, is it almost time to "watch" Corey Brown? BA up above .232, although some of that came when H'burg beat someobody 17 - 2.
