BOSTON - Joe Girardi and Brian Cashman are finally on the same page regarding the possibility of Alex Rodriguez playing first base.

"I just don't think Alex is ready to do it," Girardi said Wednesday. "I don't sense that he's comfortable there. You can tell when a guy's comfortable . . . I don't feel he's ready to go out there, so I'm not going to put him out there."

That was a change from Monday and Tuesday, when the manager insisted putting A-Rod at first, something he hadn't done since April, was a serious consideration. Each of those days Cashman said it wouldn't be his first choice, saying Chase Headley, Dustin Ackley, Brendan Ryan and even Austin Romine were his preferred candidates.

Before Wednesday's game, Cashman said Girardi's change had nothing to do with any conversations between them.

"I wouldn't say that I convinced him, no," Cashman said. "I think he's just exercising his ideas and thoughts about trying to find flexibility in the roster and then he comes to a decision. In the end it's his call."

Cashman said "it's possible" CC Sabathia, on the disabled list since Aug. 24 with right knee inflammation, will be able to return when his 15 days are up.

"He's kept the arm going, so yeah," Cashman said.

The Yankees are likely to insert a sixth starter during an upcoming stretch of 13 straight games Sept. 4-16, and Sabathia is a candidate if he's ready.

"As of right now, he'll be in the rotation," Cashman said. "That's what we're planning on."

Righthander Andrew Bailey made his first big-league appearance since July 12, 2013, and was not sharp, allowing one run, one hit and two walks in one-third of an inning. "I have to be better," Bailey said. "I know next time out will be better."
