Sheffield placed on DL; Rivera out with back spasms

DETROIT -- The New York Yankees placed outfielder Gary Sheffield on the 15-day disabled list Thursday and All-Star closer Mariano Rivera hurt his back while getting dressed before their game against the Tigers.

"He had one shoe on, and when he went to put the left shoe on, something spasmed," manager Joe Torre said before the game. "It's something new every day."

Without Rivera, the Yankees lost 7-6 when replacement closer Kyle Farnsworth allowed two runs in the ninth inning.

"We do take Mo for granted," Torre said. "That's not taking anything away from Farnsy, but that's not his job. He's a setup man."

Rivera, who said he hoped to be ready for Friday night's series opener in Baltimore, didn't enjoy watching Farnsworth's collapse

"Feeling like this is horrible," Rivera said. "It's tough -- real tough. That was my job out there. I was pulling for Kyle."

Torre wasn't hopeful.

"The way he's walking around, I don't think it is going to change too quickly," he said. "He's pretty uncomfortable."

Sheffield had been bothered by a wrist injury since an April collision with Toronto's Shea Hillenbrand, and he aggravated it earlier this week.

Tests showed a torn ligament in the wrist, as well as a tendon that continues to dislocate. He will be placed in a splint and undergo physical therapy.

"Surgery is not recommended at this time," general manager Brian Cashman said during the game. "But if therapy doesn't work, it isn't out of the question. It's a serious injury."

Sheffield was on the 15-day disabled list from May 6-23 with the same injury.

He was replaced on the active roster by outfielder Kevin Thompson. Thompson hit .383 for New York in spring training and was hitting .288 in 36 games for Triple-A Columbus.

"He'll get to play some off the bench," Torre said. "He's got tools."

The Yankees were also without captain Derek Jeter for the second straight game. He was ready to play after missing Wednesday's game with a sore right palm, but Torre decided to give the shortstop another day off.

"If we need him to pinch-hit, he's all right to do that," Torre said. "He's just been in such a great rhythm that I don't want him to favor something and get knocked out of that."

Johnny Damon did return to the starting lineup for the first time since Tuesday, wearing special padding on his injured toe.
