He didn't really give up a lot of HR's in his first stint. Just 3 in 53 IP which is amazing (hasn't allowed a HR since being recalled also). His problem was that he allowed a lot of hits because the Nats defense let him down. He had a .367 BABIP in his first stint. What is unusual though is that he had a decent K/BB rate in his first stint, but now he is walking more guys than strikeouts. He obviously isn't as good as his ERA in September, but I think he can be a 4 ERA guy next season. The key for him will always be if he can control his walks.
Yeah, you're right. I totally misremembered that for some reason.
He was definitely too hittable, though. I don't even think it was the defense that let him down; he simply allowed far too many line drives.
