He's the best defensive 2nd baseman in the league right now, and he's been one of the few guys in the lineup over the past week or two that has been hitting balls hard (along with Candy, Miggy and Tork)... and outside of Abraham Toro, he has one of the worst BABIP's in the league, suggesting a significant amount of bad luck.
If you want to find a player to pick on, I'd suggest Robbie Grossman.... I like Robbie, but there's very little positive to say about his game at the moment.
