Gardner still possible in center

The Yankees are still considering moving Brett Gardner to center field and Curtis Granderson to left for 2013. But Yankees GM Brian Cashman and manager Joe Girardi said Monday night they have yet to make a decision.

"I guess it is something that we will talk about," said Cashman, who was at the Hard Rock Café to support Yankees radio producer/engineer Carlos Silva, who is fighting cancer. "I don't know yet."

Who is the center fielder, on paper?

"Curtis Granderson is currently in center field," Cashman said. "We also have Brett Gardner, who is also a center fielder playing left field."

Girardi also said the Yankees haven't made any final decisions yet. Advanced metric suggest the Yankees could be better with Gardner in center.

Granderson has played 22 games in left in his major league career, but hasn't been on a corner since 2007.

MO WILL BE READY: Mariano Rivera said he will be on time for spring training when pitchers and catchers report Tuesday.

"I'm excited and can't wait for it," Rivera said.

Rivera, 43, is usually an excused absence for the beginning of training camp.

"This time I'm going to show up for the physical," said Rivera, who is returning from knee surgery.

Rivera said he will just pitch his six to 10 innings and he will be ready to go. He said his right knee, which forced him out last May, feels very good.
