Let him watch a couple Hulk movies, then go out there and...Arcia SMASH! Seriously, the other guys are right, this is just a rookie going through some uncertainty at the plate. Exactly what pitchers try to do, get batters doubting themselves by messing up their rhythm at the plate. Or in this case, their stance. Oswaldo Arcia got the early call because he has a short, compact, powerful swing with lots of inside-out punch. Lately he's kind of lost that inside-out punch, so the ball's not exploding off his bat like it used to. Like Morneau, Arcia's batting stance has lost its aggressive look, where he leans out over the plate a bit more, and stays there throughout the swing. Instead, like Morneau, he's standing just a bit more upright, leaning just a bit away, giving up the outside corner and losing the inside-out punch that really sends a baseball screaming off the bat. Arcia will get it back because his swing is in muscle memory, so hitting off a tee for awhile could do it, or just some extra soft-toss batting practice. Pitchers do everything they can to disrupt a hitter's rhythm and mechanics, and sometimes the disrupted stuff becomes a bad habit. The other thing Arcia must do is figure out what pitchers are doing right to make him do things wrong. Whatever they're doing, he can't let that trigger his bad habits. My guess is that Arcia will emerge from his current slump with a vengeance. Like Morneau used to do.
