Mo has polyps removed from vocal cords
NEW YORK -- Yankees closer Mariano Rivera's surgical procedure to remove polyps from his vocal cords went as expected, his agent said.

"Everything went OK [Friday] morning," Fernando Cuza wrote in an e-mail.

Appearing on Thursday at a Salvation Army event in New York, a raspy-voiced Rivera said that he will be unable to speak for a week following the surgery, which was performed at New York-Presbyterian Hospital.

Major League Baseball's all-time saves leader said that he expects to be back to normal after a week of rest, and the situation is not expected to affect his timetable of preparing for Spring Training.

"I don't like surgeries, but the sooner, the better," Rivera said on Thursday.

Rivera expressed some concern about the polyps, which will be sent to a laboratory for precautionary testing.

"I talked to the doctor and she said it doesn't look ... serious," Rivera said. "But again, you have to take it to the lab, and we'll find out."

Rivera, who turned 42 on Tuesday, enjoyed another excellent season in 2011, eclipsing Trevor Hoffman to set the Major League record for career saves.

The closer had 44 saves, bringing his career total to 603, while posting a 1.91 ERA -- his fourth straight season with an ERA below 2.00 and a WHIP under 1.00.
