Mariano Rivera is arguably the greatest closing pitcher to ever play the game of baseball. With the 2013 coming to an end, so did Rivera's career.  After 19 seasons with the New York Yankees, he finished with record saves totals of 652 in the regular season and 42 in the postseason.  His signature cut fastball seemed to defy the laws of physics and broke hundreds of bats throughout the years.

This auction item provides the opportunity to own a signed ball by the greatest closer of all time and a likely candidate to become unanimously elected into the Baseball Hall of Fame.
