Historic game used baseball signed by MLB's all-time saves leader Mariano Rivera. Official Major League (Selig) ball has been nicely rubbed up for game action and was used during the 2007 season to record the last out of one of his league-record 652 saves; signed by the Yankees closer in 8/10 blue ballpoint pen on the sweet spot with the inscription "07 Game Used." In the panel just below the seam is written "Last Out," all in Mariano's hand. Though not specifically dated, ball comes with Steiner holo and included LOA is signed by the only player in baseball history to receive a perfect 100% vote total into the Hall of Fame, and reads, in part, "I hope this unique collectible adds to and compliments your memorabilia collection, as my personal game used items are very special to me."
