I think Jr. is still hurt which explains why he isn't really hitting the ball hard. But his OBP is pretty high because of all the walks. What is interesting is how the numbers suggest he has also changed his aggressiveness at the plate. Last year he had a walk every 10 AB's (39 walks in 428 AB's). This year he walks nearly once in every 4 AB's (9 in 42 AB's). And look at the drop in strikeouts. Last year he struck out about once every 5.5 AB's (78 out of 428). This year he has only struck out 3 times in 42 AB's.
Is this a small sample size issue that will correct? Is he not getting pitches to hit, correctly not chasing them, and taking the walks given? Is this a guy that's hurt and won't swing the bat? Or is this reflective of a guy who believes he can't drive the ball, has stopped trying and is now simply trying to get on base?
