CC OK after hit by comebacker

CLEARWATER, Fla. -- The last thing the Yankees need at this point in the spring is a serious injury scare involving CC Sabathia, so they breathed a sigh of relief when the big lefty ordered them off the field on Thursday.

Sabathia was struck in the right thigh by a John Mayberry comebacker in the second inning at Bright House Field, then picked up the ball and threw out the runner at first base.

Team medical staff and manager Joe Girardi immediately charged out of the dugout to look at Sabathia, but they only got as far as the foul line before Sabathia put up his hand and waved them back to their seats.

"It still hurts, but it's all right," said Sabathia, who iced the area after he exited. "I've got a lot of meat down there."

Rebounding from his annual bad second start of Spring Training, Sabathia limited Philadelphia to three hits over five scoreless innings, walking none and striking out two.

"CC looked really good," Girardi said. "He still didn't even hit his pitch count. That's pretty much the CC we're used to seeing."

Sabathia credited the work that he and pitching coach Larry Rothschild did in the bullpen.

"I have a pause in my delivery," Sabathia said. "I was kind of floating and drifting through it instead of just staying there, gathering it and going. I was conscious of it in the bullpen today, and it translated into the game."

Posada flashes some leather playing first

CLEARWATER, Fla. -- Jorge Posada might not have been the most comfortable man on the field, but he looked right at home playing first base in the second inning of Thursday's game, turning an unassisted double play.

Making his first appearance in the field this spring, Posada snatched a Placido Polanco liner and alertly tagged Shane Victorino to complete the double play.

"It was self-defense," Posada shrugged. "It was right at me."

The 39-year-old Posada doesn't figure to see much time in the field this year, with the Yankees having moved him from catcher to designated hitter.

However, the Yankees would like to at least keep Posada -- who has played 28 games at first base in his career -- ready in case they need someone to step in behind Mark Teixeira.

"You feel a little bit like a fish out of water," Posada said. "You have to catch ground balls and get prepared and make sure that you catch the throws. It's different. You've just got to stay on your toes."

CC Sabathia said that Posada didn't look half bad there.

"It was funny," Sabathia said. "He made some good plays, though. He picked a ball out of the dirt that [Ramiro] Pena threw over there. Get used to it."

The Yankees are considering carrying Eric Chavez or Jorge Vazquez to begin the year, both of whom can play first base, and Nick Swisher is also capable of manning the position.

"We don't know exactly what the makeup of our team is," manager Joe Girardi said. "Our plans are for [Posada] to DH, but let's say you decide you want to DH Tex and keep Swish in right field. You might put Jorgie at first to keep his bat in the lineup."

Of course, Posada was once an infielder, coming up through the Minors as a second baseman for a period of time. But enough years have passed that standing on the infield feels foreign.

"It's very different," Posada said. "It's a process, especially with guys on base and balls hit in the outfield, where you have to be on double [plays]. It doesn't come instinctively to me. I have to think about it beforehand."

Curtis out a month with separated shoulder

CLEARWATER, Fla. -- Outfielder Colin Curtis will be sidelined for at least a month with a separated right shoulder.

Curtis, 26, landed on the shoulder while making a diving catch in Sunday's Grapefruit League contest against the Astros in Kissimmee, Fla. He will remain in Tampa, Fla., for rehab.

"[It's] kind of unlucky," Curtis said. "Sick catch, though."

Curtis batted .186 with one home run and eight RBIs in 31 games for the Yankees last season, his first big league experience.
