In news that doesn't come as a major shock, but is huge nonetheless, Yankees closer Mariano Rivera is reportedly set to announce his retirement at the end of the 2013 season this Saturday (h/t Joel Sherman via Twitter).
The 43-year-old will go down as the greatest reliever of all-time, as he's used his legendary cutter to rack up a record 608 regular-season saves to this point and has another 42 saves with a 0.70 ERA in the postseason.
Rivera missed most of the 2012 season after tearing his ACL in early May, but the team had the luxury of another All-Star closer in Rafael Soriano ready to step in.
They won't have such a clear cut in-house option this time around, and who fills the ninth inning role in the Bronx next year will no doubt be an area of much debate throughout the season.
Here is a look at some early candidates to take over for Rivera in 2014.
