Will there be any penalties to my SP if I temporarily convert him into a RP?

[Libid21]

I'm playing as the Yankees, and all of my pitchers are doing well. Burnett went down, and Hughes came up to fill in for him and he's pitching a 3 ERA right now throughout two-three weeks. No one, except Pettite, has an average near 4.30 ERA (that's Pettite's)... I'd rather keep Pettite in my rotation but I'm not sure what I should do...

will there be a penalty if I put Hughes in the bullpen? Or do you guys think I should just let him eat up some innings in AAA until one of my other starters, knocking on wood, gets hurt again?

Thanks.

I've never seen any negative impacts on SP->RP.

It's always RP->SP that has the issues. Of course, if they're a SP to start with, I doubt it's as big of an issue. Keep in mind though, it usually takes a couple of starts to get a RP->SP up to "full strength" in terms of pitch counts, just like real life.
