One of the big reasons he got traded is that he complained that he wasn't getting the chance to start. I saw an unsubstantiated mention that he might've tanked some out of the bullpen in protest. Don't know any other details around that whole situation, but that's the situation being referenced in all likelihood. It says a lot about how low their opinion of him was that they essentially gave him away rather than letting him start, probably knowing that they were about to open up at least 1 rotation spot not 24 hours later. Well if the rumors are true that he intentionally tanked, you pretty much have to get him off your team.
