Hall of Famer Mariano Rivera tore an Achilles tendon while going after a flyball at the New York Yankees’ Old-Timers’ Day game.

Rivera was playing centerfield in the bottom of the first inning and was seen going to the ground on his own during an infield pop.

Rivera is the first and only player to be voted into the Hall of Fame unanimously. He holds the record for the most saves in baseball history (652), he was an All-Star 13 times with the Yankees and he won five championships in pinstripes.
