No, he hasn't been a prospect since 1996, but this could very well be the last chapter in the story of a Hall of Fame career. Figured it is newsworthy for any baseball website. Girardi has addressed the media and confirmed the MRI results.
I'm no fan of the Yankees per se, but Rivera is arguably the best relief pitcher since Eckersley and one of the best ballplayers of this era. Sad to see that this is the likely end to his career, as I cant imagine that he'll rehab to come back for 2013...but I suppose stranger things have happened.
