New York Yankees pitcher Mariano Rivera will reportedly announce his future plans on Saturday.

According to the New York Post, Rivera is expected to retire following the 2013 season.

The Yankees will host a press conference at 10 a.m. on Saturday morning, though the organization did not specify the reason.

Rivera, baseball's all-time saves leader with 608, had given strong indications that he was likely going to call it a career after the 2012 campaign. However, he tore the anterior cruciate ligament in his right knee while shagging fly balls during batting practice before a May 3 game against Kansas City and missed the remainder of the season.

The 43-year-old right-hander initially said he would return for 2013 because he did not want to go out with an injury. He then reportedly was unsure before telling Yankees general manager Brian Cashman in November that he would indeed come back.

Rivera has yet to pitch in a game this spring, but is expected to make his first appearance on Saturday.

The 12-time All-Star appeared in just nine games last season and managed five saves with a 2.16 earned run average and a 1-1 record. He had registered at least 28 saves in 15 consecutive years prior to 2012.

Rivera has been even more dominant in the postseason, winning five World Series titles with the Yankees while posting 42 saves and a 0.70 ERA in 141 innings over 96 games.
