Baseball: Yankee reliever Rivera to retire this year: report

New York Yankees ace relief pitcher Mariano Rivera, Major League Baseball's all-time saves leader, plans to announce this weekend that this will be his last season, the New York Post reported Thursday.

The newspaper said that Rivera will announce his plan to retire at the end of the Yankees' 2013 campaign on Saturday, when he makes his pre-season exhibition debut on the mound.

The 43-year-old Panamanian right-hander, who have 608 career major league saves, had hinted at retirement last year but tore his right knee anterior cruciate ligament last May and missed the remainder of the season.

Rivera, a 12-time All-Star reliever, had vowed to return, saying he did not want to end his career with an injury.

Rivera has been spectacular for the Yankees in the playoffs, helping the team win five World Series titles with 42 saves and a 0.70 earned-run average over 141 innings in 96 playoff games.

Last season, he appeared only nine times, managing just five saves with a 1-1 record and a 2.16 earned run average. He had no fewer than 28 saves in any of his 15 prior seasons.
