Yankees reliever Mariano Rivera, who has been sidelined by stiffness in his left side, can close Wednesday against the Orioles, if needed.
"I could go out there, but it is their decision," Rivera told ESPNNewYork.com Wednesday morning.
Manager Joe Girardi said he is leaning toward resting Rivera for another day. Girardi said he would prefer to be cautious, and with a day off on Thursday he could give Rivera a longer break.
"I really believe that Mo is available, but if I can, it is two more days," Girardi said.
After finishing their three-game series against Baltimore (1:05 p.m. ET), the Yankees are off Thursday before playing 17 straight days, starting with a three-game series Friday in Boston.
Rivera added that the discomfort in his side "feels better," and believes he could have pitched Tuesday night.
"It wasn't necessary," Rivera said of the second consecutive day off.
Girardi said he will not use Chamberlain on Wednesday. He wasn't sure who he would turn to in the ninth.
