He's had a very good start to the season.
My long-term assessment of him (doesn't throw hard enough, no true "out" pitch, gets hit solidly when he can't locate precisely) remains unchanged, though.
ETA: Also worth noting that his HR/9 is well below his career average -- currently at .81 HR/9 off a career average (that's been pretty consistent) of 1.22 HR/9. He's succeeding, in part, this year because he's being uncharacteristically stingy with the longball.
