I looked up his plate discipline at fangraphs, and the crazy thing is, this year, he's swung at less balls outside the zone than league average, but he also swings at an above average clip in the zone -- and he doesn't really swing and miss much. Pitchers just haven't been throwing him balls. Hopefully he'll get a little more selective, but when your manager seems to only let you play when you got a hit the day before, that would be hard to do.
