With Kearns day-to-day, Yanks make move

NEW YORK -- Austin Kearns remains day-to-day with a bone bruise on his right index finger, suffered in batting practice on Friday.

With Kearns' availability for Monday's game with the Orioles in question, the team called up outfielder Colin Curtis from Triple-A Scranton/Wilkes-Barre.

"Just with some of the injuries we have in the outfield, we thought we could use another outfielder," manager Joe Girardi said. "It just gives us some flexibility."

Kearns was able to play the field for an inning on Sunday, but Girardi didn't think he would have been able to take his subsequent turn at bat if the Yankees had come back in the bottom of the ninth.

Curtis played in 22 games earlier this season for the Yankees, hitting .256 with a home run in eight RBIs.

Pettitte clears final hurdle before rehab start

NEW YORK -- After coming through his bullpen session on Monday with no issues, Andy Pettitte is set to make a rehab start on Thursday night for Double-A Trenton.

The original plan called for Pettitte to start on Wednesday, but the team decided to push him back a day to keep him on a normal routine, manager Joe Girardi said.

Pettitte threw roughly 20 pitches in the same down-hill bullpen session that he typically tosses before a start.

"I felt good," Pettitte said. "I'm looking to get through [Thursday] feeling good."

Pettitte will start Game 2 of Trenton's playoff series with New Hampshire on Thursday night. He's scheduled to throw 65 pitches or complete four innings -- whichever comes first, according to manager Joe Girardi.

Girardi has said that he's comfortable with Pettitte pitching for the Yankees on a 75-pitch limit. At the same time, he'd rather Pettitte make a second rehab start in the Minors in order to reach that mark before rejoining the big club.

"The one thing that you want to look at when you're talking about pitchers, if he gets to 65 [pitches on Wednesday], then the area of concern the next time is 65 to 80," Girardi said. "So if he's at 75, you know he should be fine all the way up until 75 and then you wonder if he gets a little fatigued after that."

If Pettitte does make a second rehab start roughly one week from now, that would line him up to return to the Yankees' rotation in Baltimore from Sept. 17-19. Since the Minor Leagues are in their postseason, however, it's not clear when and even if Pettitte would be able to make that second rehab start.

Pettitte has been sidelined since July 18, when he left his first start after the All-Star break with a strained left groin. The left-hander was 11-2 with a 2.88 ERA before the injury.

Relieved Swisher back in the field for Yanks

NEW YORK -- Nick Swisher was back in the starting lineup on Monday, hitting second and playing right field.

Swisher had missed the previous three games with stiffness in his left knee. An MRI on Sunday, though, revealed only a deep pocket of inflammation in the knee, meaning there is no structural damage.

"We know there's no structural damage," said Swisher, who admitted he was very relieved with the results. "The biggest thing for us to know is if we can deal with the pain so we can deal with playing."

Swisher did pinch-hit on Sunday, grounding out to first. He was not able to stay in the game in the field, however, since the knee prevented him from running full-speed. He ran before Monday's game to make sure he had no issues in the outfield.

Worth noting

Entering Monday's tilt, the Yankees are 33-26 on Labor Day since 1961. ... A.J. Burnett and CC Sabathia, who are starting the first two games of this series with the Orioles, are a combined 24-4 in their career against Baltimore. The pair is 6-1 vs. the O's this season. ... New York relievers have combined for a 1.60 ERA since July 26. ... Left-hander Boone Logan has retired 31 of the last 36 left-handed hitters he has faced. ... Manager Joe Girardi brought a coffee machine into the team's conference room to help combat the fatigue caused by five consecutive day games. The Yankees are second in the Majors with their 34-17 record on day games, behind only Oakland (31-15).
