Wright and Chacon suck so much at even given the Yankees innings, that Torre has been forced to stick Wang in between them to rest the bullpen. I can give Chacon some slack because hes only had two starts since coming of the DL, but Wrights been fine for awhile now and for some reason can't build up enough stamina to get through even 6 innings.
And while everyone continues to say Wang is a fluke, I think its been proved that he really isn't. Hes not going to K alot of people, but he gets so many ground balls, and his BABIP has stayed the same, that I really think hes going to continue being a good number 3 guy in the MLB.
