Once they get through this series and the bullpen is back to normal rest (IF) you'll probably see Pomeranz go back down or Gregg sent packing. I can't see any other pitchers going unless the O's get revolutionary (the Angels did it one year) and go for the best 7 instead of worrying about the lefty matchup thing. That could mean keeping Pomeranz and moving Patton, who isn't a true matchup guy anyway. In fact, I thought it was funny when he removed O'Day who had given up something like one hit all year to a lefty, in favor of Patton, to pitch to Gonzalez and the Papi the next inning (leadoff double).
Strictly based off of last night and what he has done in the minors thus far this yearm Pomeranz is in my BP over Patton...but no way the old school Buck Showalter has no lefties in his BP.
