It makes sense on many fronts:
1. Brian Cashman didn’t trade Jose Tabata and the three pitchers to let Marte go after two months.
2. The Yankees have been crying for a good lefty reliever for years now. Mike Stanton’s last good year in pinstripes was 2002.
3. Phil Coke is not the answer, not yet anyway. He was a stumbling-along prospect who broke through last season and pitched well in a series of generally meaningless September games. Let’s not get too excited. Besides, bringing Marte back allows them the luxury of seeing whether Coke can develop as a starter.
4. Joe Girardi’s strength as a manager is handling the bullpen, so give him pieces to work with. The rotation could have a guy coming off a serious injury (Wang), a guy coming off a cranky shoulder (Pettitte), a guy coming off throwing 500+ innings over two years (Sabathia) and who knows what else?
Getting two draft picks for a set-up man would be a nice haul. But the Yankees will get their extra picks one way or another. Keeping Marte improves the roster right now.
