NYY@SEA: Nuno holds Mariners one run over 5 2/3

NEW YORK -- Yankees manager Joe Girardi maintains that he does not plan to make any changes to the rotation as of now, but he has to be watching left-hander Vidal Nuno closely.

Nuno was roughed up by the A's during his last outing on Sunday, surrendering eight runs in three innings. His ERA during his three starts in June is 7.43, and his overall mark stands at 5.90.

The Yankees are 5-6 in games in which Nuno starts, including 1-5 at Yankee Stadium, the sight of Nuno's next scheduled start, against the Orioles on Saturday.

"I don't ever put that type of pressure on people," Girardi said. "They understand what is on the line every day, and they understand that this is a performance-based business."

During his bullpen session Wednesday, Nuno worked on finding the right grip on his cutter, which he said will be essential for his success. He said he is not worried about pitching for his job.

"It's the nature of the game," he said. "It's in the back of my mind. I've been working on stuff day in and day out, but I'm just going to go out there, enjoy it and have fun.

"If I can't do that, I'm just going to keep fighting and see where it takes me. I don't think about [losing my spot]."

Warren strong possibility to move into rotation

LAA@NYY: Warren induces double play to end 7th

NEW YORK -- Yankees reliever Adam Warren's name continues to emerge as a candidate to join the starting rotation, now that Shawn Kelley is back in the bullpen.

Warren has yet to make a start this season, but he is 1-3 with a 2.19 ERA, with 36 strikeouts in 37 innings as the Yankees' long reliever.

Manager Joe Girardi estimated Warren could give the Yankees approximately 45-50 pitches at a maximum, however Warren would not necessarily need to be sent down to the Minors in order to raise his pitch count. The Yankees stretched Joba Chamberlain's pitch count to a starter's level a couple of years ago in a similar situation.

"You do it slow, almost like building up in Spring Training," Girardi said.

Girardi wants to keep at least one long reliever in the bullpen, so Kelley's return to action gives the manager some flexibility. Girardi likes Warren in the spot the righty is in now, but the Yankees could use some help from a rotation that, other than Masahiro Tanaka, has struggled to produce consistently.

"There's conversations that we have all the time," Girardi said. "We'll continue to look at things."

CC Sabathia (knee) and Michael Pineda (shoulder) each have missed significant amounts of time due to injury. Sabathia is currently undergoing a Spring Training-like rehab to stretch his arm back out and hope the pain is gone from his right knee. And Pineda likely will not return to the rotation until at least August.

Bombers bits

• Sabathia threw a 25-pitch bullpen session on Wednesday, his second consecutive day throwing off the mound. He is scheduled to throw again Saturday, barring any setbacks.

Sabtahia has been on the disabled list since May 10 while rehabbing a right knee stem-cell injection.
