Yanks trade Shawn Kelley to the Padres (UPDATED)

According to Robert Murray and Chris Cotillo, the Yankees have acquired Johnny Barbato from the Padres for reliever Shawn Kelley. Barbato is a 22 year old right hander who last pitched for Double-A San Antonio in the Padres' system. He was 2-2 with 2.87 ERA and earned 16 saves.

** UPDATE 6:26 PM** - Interesting comment by Kelley on the trade, via Dan Barbarisi:

"[Cash] said he hated to see me go, but they have some things they’re doing, things they’re working on, and it was part of new plan.”

A new plan, eh?  What's involved in this new plan?  What else are the Yankees working on?  Gotta think it's another rotation piece, no?
