Posada 'back to 100 percent'

After throwing out three of four runners in yesterday's minor-league game, Jorge Posada said his shoulder is "back to 100 percent."

"Now you know that you can trust your arm again," he said. "That's the only thing I wanted to do. Come out of spring training knowing that I can throw somebody out and trust my arm again . . . Today's special. You throw a couple guys out and you feel good about that."

Posada caught CC Sabathia against Pirates' minor leaguers at the Yankees' minor league complex in Tampa. Sabathia struck out four and allowed one run in 5 1/3 innings (81 pitches).
