TAMPA, Fla. (AP) - Mariano Rivera's family is on its way to Florida for the expected announcement that one of baseball's greatest relievers is retiring after the season.

There have been numerous reports - one by The Associated Press - that this will be the last season for the 43-year-old closer.

A news conference is scheduled for Saturday at the Yankees' Spring Training complex in Tampa. Rivera said after working out Friday that those wanting to know his plans will have to wait. He said "whatever's out there is speculation until I talk to you guys.''

Rivera is baseball's saves leader with 608. He is regarded as one of the best clutch pitchers in history, posting a record 42 postseason saves with an 0.70 ERA while helping the Yankees win five World Series championships.
