He's given up way too many HR's but that is really my only complaint with him so far. You also need to keep in mind he's still relatively young as a pitcher. He only had two partial seasons in Toronto where he pitched a total of 235 innings. He'll be up and down this year and will likely really come into his own next year. I'd expect a career path similar to Cappy though he won't ever be as good as Cappy has been this year.
