BALTIMORE — The Yankees haven’t listed a starter for Sunday’s game against the Rangers, but that doesn’t appear to be because of a problem with CC Sabathia’s right knee.

Sabathia, whose regular turn is Sunday, left the Yankees on Wednesday to travel to New York, where he was examined Thursday by team physician Chris Ahmad. Sabathia said Wednesday he was slated for a lubrication injection in the hinge that caused him to be on the DL in the middle of August.

“He will join us in Texas. He went to see the doctor, just trying to keep up on that,” manager Joe Girardi said before Thursday’s 9-1 win over the Orioles at Camden Yards. “As far as his knee, it is fine but he talked about the maintenance program, staying ahead of it, and that’s what they are trying to do.”

Girardi said Sabathia is staying on schedule but added: “I am not sure [what that schedule] is though now.’’

As Aaron Judge stood in front of his locker ready to answer postgame questions Thursday, Red Sox second baseman Dustin Pedroia was on the TV above Judge’s head talking about the Apple Watch controversy.

Judge listened, and when asked if he wanted to comment on Pedroia’s remarks, he smiled and shook his head.

The additions of David Robertson and Tommy Kahnle to the bullpen July 18 and the development of Chad Green have the Yankees in better shape to handle losing Adam Warren this time than when the right-handed reliever went on the DL June 16-July 4 with an inflamed right shoulder.

“Our bullpen struggled the last time he went out,” Girardi said Thursday, a day after Warren was put on the DL with lower back spasms. “I think we are a little bit better equipped now than we were then. But we are going to miss him.”

Though Aroldis Chapman and Dellin Betances receive most of the attention in the Yankees pen, Warren has played a big part in the bullpen being ranked third in the AL with a 3.44 ERA and first in batting average against (.209). Twenty of Warren’s 45 appearances have been more than an inning.

He is 3-2 with a 2.40 ERA, has allowed 35 hits and struck out 53 in 56 ¹/₃ innings.

“It hurts because he was a multiple-innings guy, sometimes a bridge guy,” Girardi said. “If your starter’s pitch count got high, wasn’t effective for the first four innings or you didn’t like the matchups coming, he was a guy who could give you two or three innings.”

Warren has been told to rest for two weeks, which might mean he won’t make it back during the regular season. Girardi said he believes, however, there is a chance Warren will make it back because he is a reliever.

“If he was a starter, you would be more concerned,” Girardi said. “Because he is a reliever, it’s definitely possible.”

Asked before the game who his closer would be, Girardi didn’t commit to Chapman or Betances.

“I don’t know yet,” Girardi said. “I will look at everything. I think I have a lot of options.’’

Chapman threw a perfect eighth inning Tuesday night, when Betances gave up a game-winning, two-run homer in the ninth to Manny Machado for his third blown save. The performances fueled speculation Girardi would return Chapman to the closer’s role he handed to Betances after Chapman gave up two hits and two runs in an inning against the Red Sox on Aug. 18 at Fenway Park.

Gary Sanchez will come off suspension Friday, when the Yankees open a three-game series against the Rangers in Arlington, Texas.

Though MLB hasn’t announced if Austin Romine will serve his one-game suspension Friday, that is a strong possibility.
