Damon batted second in several games during spring training when catcher Jorge Posada, coming back from right shoulder surgery last July 30, batted first in order to get extra at-bats.

"I'm OK with it," Damon said. "We all know Derek's on-base percentage. Hopefully I can continue to feel comfortable in that position. The good thing about it is Derek and I both want to win. I just think this possibly could be better for the team."

Jeter had left the ballpark before the clubhouse was opened to the media late in the Yankees' 10-2 win over the Philadelphia Phillies on Thursday.

"I showed it to him Tuesday night and he said, 'Great,"' Girardi said. "He was fine with it. He's done it before, so this is not something new for him. Probably a little more with Johnny, but Johnny felt very comfortable there."

Jeter went 2-for-4 with two runs scored. He worked a 3-2 count before hitting an infield single leading off the first.

"Jeet has that ability," Girardi said. "There's times he's aggressive in the count, and there's times he can work the count. He did a nice job leading off today and he'll do it again tomorrow."

Damon had one hit in four at-bats, including an RBI single that scored Jeter, who had doubled, in the fifth.

No. 5 starter Joba Chamberlain, on an innings limit this season, is set to make his first start in the Yankees' sixth game, at Kansas City on April 12.

"I think his development has went pretty well," Girardi said.

Chamberlain allowed two runs - on first-inning solo homers by Chase Utley and Ryan Howard - and three hits in 4 1-3 innings. He threw 40 of 76 pitches for strikes.

Girardi is looking forward to the home opener next month.

"Electric," he said. "I think it's going to be like little kids in a candy store."

Notes

Long relief candidates Brett Tomko, Alfredo Aceves and Dan Giese will pitch on Saturday. "We need to see all three pitch again," Girardi said. ... The Yankees likely will decide this weekend whether Brett Gardner or Melky Cabrera will start in center. Gardner is thought to be the front-runner.
