The guy has been pretty good for the O's and has gotten a ton of K's. His injury is an issue, but I think if he hadn't gotten hurt, this trade wouldn't have happened.
Sure, he's been pretty good. But he is 100% untested as a late inning (8th-9th) guy in a pennant race, not to mention the playoffs. BTW: being out injured is a pretty big issue Obviously it would depend on how he was pitching at the time as far as whether the trade would have happened or not had he not been injured.
