⚾ Mariano Rivera Signed New York Yankees Grey Baseball Jersey JSA COA/LOA – A JSA Authenticated Autographed New York Yankees Away Grey Jersey from the Greatest Closer in the History of Professional Baseball

⚾ The conversation about the greatest closer in baseball history begins and ends with Mariano Rivera – a right-hander from Panama who arrived in the Yankees organization as a starting pitching prospect and transformed himself into the most dominant relief weapon the sport had ever seen, relying primarily on a cut fastball that broke bats, induced weak contact, and defied the ability of even the best hitters in the game to solve with any regularity across nearly two decades. Rivera recorded 652 career saves – the all-time MLB record – across nineteen seasons in the Bronx, won five World Series championships with the Yankees, was named the 2009 World Series MVP, and was selected to thirteen All-Star games across his career. In 2019, Rivera became the first player in baseball history to be inducted into the National Baseball Hall of Fame by a unanimous vote from the Baseball Writers' Association of America, a recognition that stood as a testament to the singular nature of his career.
