Mariano Rivera was simply the greatest close of all-time and one of the most dominant pitchers to ever step on the mound. Rivera anchored the Yankees bullpen, leading them to five World Series titles and retiring as the all-time saves leader in baseball history. Rivera became the first ever player to be unanimously inducted in to the Hall of Fame. Offered here are 24 single-signed Mariano Rivera baseballs. Rivera signed his name on each baseball in blue pen and all across the sweet spots. All of the baseballs are Official Major League Allan H. Selig stamped balls. This entire lot comes with a JSA Auction Letter.
