His wOBA (.382) is second on the team, behind LaRoche (.390).
What's interesting is that Harper is listed as having a -5.0 "baserunning" value so far, which I can't seem to understand as he has taken a ton of extra bases and stretched some singles into doubles. Can someone who is more stat-savvy (JCA?) explain that? I know the baserunning stuff is pretty new, but it seems out of whack with my mindfacting.
Edit: I was looking at fielding, not baserunning. Sorry! His baserunning is listed at 1.5, which is first on the team and close to the league leaders.
