New York Yankees closer Mariano Rivera confirmed Saturday the worst-kept secret in spring camp when he said he'll retire at the end of the 2013 season.

"After this year, I will be retired. Now you're hearing it from me," Rivera said at a news conference in Tampa, Fla.

Rivera, 43, has a record 608 saves and five World Series rings. But he tore the anterior cruciate ligament in his right knee last May 3 while shagging fly balls during batting practice.

Rivera made his first game appearance since April 30, throwing a 1-2-3 fifth inning against Atlanta on Saturday.

Shortstop Derek Jeter also made his spring training debut in the Yankees' 2-1 loss. He was a D.H. and went 1 for 2. Jeter suffered a broken ankle Oct. 13 in the ALCS against Detroit.
