True. However, his coach shouldn't let him show up umpires, make gestures at the crowd, flip his bat, etc. You can show a little swagger without disrespecting the game and those around you.
Absolutely agree! You'd think the coach or at least his "advisors" would tell him to cut the hot dog, prima donna stuff. (actually, shouldn't his old man step in and say 'knock it off, this isn't good.") And the face paint has got to go. Just shows this kid has a long way to go. If you think you can play with the big boys, start acting like it. Otherwise, he may be seeing a few games from the seat of his pants after some chin music. Imagine what Gibson, Drysdale, or Ryan would've done to someone showing them up flipping a bat or wearing facepaint? Next place you would've read about that player would be in the obits.
Never too early to start cultivating a positive image. It's working pretty well for Joe Mauer.
