Yankees closer Mariano Rivera says he will have surgery Friday to remove polyps from his vocal cords.

Talking on Thursday at a charity event, Rivera said the operation at New York-Presbyterian Hospital will prevent him from speaking for a week.

''I don't like surgery, but the sooner, the better,'' Rivera said.

Rivera, who turned 42 on Tuesday, had 44 saves this season to increase his career total to a record 603.
