For a guy with a rep as not having great plate discipline when we drafted him, he seems to be taking a lot of walks last year and this. They also said he'd take BBs when he was pitched around. if that's what's happening, then he's being pitched around a lot. 130 PAs over last year and this, 19 BBs, 29Ks.
I suppose a guy with good plate discipline would have closer to 1:1 BB:K in low minors.
