What to Do With Chien-Ming Wang?

Through 3 1/2 weeks of the season Chien-Ming Wang has been the worst pitcher in major league baseball. He was so bad that the Yankees basically just told him to go on the Disabled List with "Hip abductor muscle weakness". And by that they mean incredibly bloated ERA. Last night marked a potential crossroads for Wang. Phil Hughes, the Yankees top prospect, filled in and threw a gem. Hughes last 6 innings, struckout six and gave up just 2 hits and 2 walks total. If Hughes goes out and has a few more solid outings than where does that leave Wang. Hughes is the Yankees top prospect, if he goes out and pitches well, in reality there's no reason the Yankees should take him out of the rotation even if Wang is theoretically back to the 19 game winner of 06-07. Obviously, Burnett and CC aren't going to the bullpen anytime soon. Andy is likely to old and prideful to accept a demotion, and is 2-1 with a 2.96 ERA thus far this season. Thus that leaves either Wang or Job...
