On the Yankees beat

News from the pregame locker room:
-- Jorge Posada will miss the weekend series against the Royals with a tear of a hamstring tendon. Koyie Hill was in the locker room and will be added to the roster before the game to back up Kelly Stinnett. Posada is expected to miss 3-7 days.
-- Joe Torre said the Yankees are leaning toward giving Jaret Wright a couple of extra days to rest his tight groin and could start Aaron Small on Sunday. Wright would go Tuesday in Detroit.
-- Torre answered a question from WFAN's Sweeny Murti by nodding his head. Realizing what he did -- a radio reporter kind of needs a verbal response from the other end -- Torre said, "It doesn't help you for me to shake my head when you have a microphone here, right?"
