NEW YORK -- Shawn Kelley threw about 25 pitches in a simulated game on Wednesday at Yankee Stadium and has been cleared for a Minor League rehabilitation assignment with Double-A Trenton, beginning on Saturday.
It is possible that Kelley could be activated from the disabled list to rejoin the Yankees' bullpen on Monday in Kansas City. He said that he felt strong in the session, in which he threw to Kelly Johnson and Scott Sizemore.
"We'll see how it feels after Saturday," Kelley said. "If I need another one, then we'll do it. If I feel fine and my stuff's there, that might be the only one. I feel normal. I feel like I did before my back hurt."
Kelley has not pitched in a big league game since May 6 in Anaheim due to a strained lumbar spine. He is 1-2 with a 3.52 ERA in 16 appearances this season.
