In his blog today, his source is pretty credible.
http://yankees.lohudblogs.com/Torre said [t]here would a move in the bullpen tomorrow. You have to think Sean Henn is out. No idea who will be back but I pray it’s Chris Britton so people will stop e-mailing me.
If Henn is out, we have no lefty or Ortiz. As much as I would like to see Britton, I have a feeling it's going to be Karstens because he could be a long man where Britton is just an inning or two.
Edwar might also be sent down. Hopefully Britton is up though.
