Mariano Rivera has sore triceps

CLEVELAND -- New York Yankees closer Mariano Rivera was not available for Monday night's 6-3 loss to the Cleveland Indians because of a sore right triceps muscle.

Yankees manager Joe Girardi revealed Rivera's condition following the game. He said Rivera told him before the game that he was sore after blowing a save on Sunday against the Mets.

"Mo's a little tender, I guess you would say, in his lower triceps,'' said Girardi, who said no tests were planned for his 41-year-old closer. "He wasn't available today and we'll see about tomorrow.''

"These are just the little things that happen, guys,'' Rivera said. "I'm not concerned about it, I can tell you that. I'm not concerned at all.''

Rivera said he could not recall ever having a similar pain in his 17-year career. He said he first felt it after coming off the mound Sunday at Citifield, after surrendering the tying run in the ninth inning of what would eventually be a 3-2 Yankees loss in 10 innings.

"When I'm pitching, I never feel anything, just after,'' he said. "After (Sunday), there was some soreness there, and today it was still sore. Hopefully, it will be better tomorrow.''

Girardi said he would have used right-hander David Robertson had there been a save situation in the series opener against the Indians. Rivera is 1-1 with 21 saves in 25 chances and a 1.91 ERA in 35 appearances.
