Alex Rodriguez in, A.J. Burnett out

NEW YORK -- Third baseman Alex Rodriguez was in the New York Yankees' lineup for Sunday night's game against the Boston Red Sox, but starter A.J. Burnett was scratched due to tightness in his back.

Rodriguez missed Saturday's game after taking a Lance Berkman line drive off his left shin during batting practice. Joe Girardi said Rodriguez felt better Sunday, but the manager did not fully sign off on having A-Rod in the lineup until he made it successfully through pregame warm-ups.

Rodriguez went 1-for-3 with a walk and a strikeout while scoring a run in the Yankees' 7-2 win over the Red Sox in the series finale. He also stole his first base since May 8. It was his 300th career steal.

After the game, Girardi said that he took Rodriguez out in the ninth because he had some stiffness in the shin. Girardi didn't think it was serious, but he said he wanted to see how Rodriguez felt Monday before he decided if he would start the Yankees' next game.

Dustin Moseley, who was slated to start on Monday, was the Yankees' starting pitcher Sunday. He gave up six hits and two runs en route to the win.

Burnett tweaked his back Saturday while working out on flat ground, but Girardi said the right-hander was feeling much better after getting treatment.

He "felt his back tighten, spasms, stiffness and we just thought it was in our best interest to move him back 'til Tuesday," Girardi said. "The thing is he goes out and starts and feels it in the first, second or third inning it kind of puts us in a little bit of a bind."

Phil Hughes will start against the Red Sox on Monday afternoon. Burnett will be moved to Tuesday in Texas.

Burnett is 9-9 with a 4.93 ERA on the season, while Moseley is 1-1 with a 4.13 ERA. With the Yankees having an off day recently, Moseley is pitching on his regular rest.

With Burnett scratched, Jorge Posada is the Yankees' catcher. If Burnett had started, Francisco Cervelli would have caught because Girardi likes how they work together.
