Oh boy.. that could be devastating for the Yankees, who have little depth beyond 4 of their starters (Tanaka, Pineda, and an aging/declining Kuroda & Sabathia). Warren and Phelps are needed in their thin bullpen, and Nuno got lit up in his last appearance (7ER vs. Baltimore last time, and hasn't pitched in 11 days. Why isn't he in AAA??).
And don't ask for help in SWB.. most of their starters are minors vets like Billings, Gordon, Leroux, and non-prospects Cotham, Whitley and Stoneburner. Banuelos, BTW, is still rehabbing from TJS.
