Roy Oswalt Wants Out of Houston

Roy Oswalt of the Houston Astros has requested a trade and agreed to waive his no trade clause to do so. Looks like Houston has a problem. Okay we knew that the bad pun was going to be used eventually, get over it. Why wouldn't Oswalt want out of a team that has the worst record in the NL? Everyone wants to win and Oswalt isn't getting that with the Astros despite a 2.66 ERA. Where would he fit in though? I could see a team that has a playoff chance take him but that won't happen until June or July when the standings become clearer. Maybe Detroit is a possibility. But of course he may not even be traded as it sounds like the Astros may not be on board. We will just have to wait and see.
