According to Buster Olney of ESPN, it’s an “open secret” that Mariano Rivera will retire following the 2013 season. The future first ballot Hall of Fame pitcher has spent his entire career in pinstripes and owns the franchise record for saves. Rivera has notched 608 regular season saves for the Yankees to go along with 42 saves in the postseason. His postseason ERA is an astonishing 0.70 in stellar his career. This announcement doesn’t come as a great shock. Rivera is 43 years old and his time in the Major League was coming to an end sooner rather than later. He will go down as one of the greatest players to ever wear pinstripes when he does retire. It’s an open secret that Mariano Rivera intends to retire, and that announcement figures to be very soon, perhaps Saturday. — Buster Olney (@Buster_ESPN) March 7, 2013 Rivera’s retirement would come at the end of the 2013 season, whenever he chooses to announce it. — Buster Olney (@Buster_ESPN) March 7, 2013 The post Report: Mariano Rivera to retire after 2013 season appeared first on New York Sports Kings.
