Closers aren't supposed to be dominant for extended periods of time, but most closers aren't Mariano Rivera. The Yankees relief ace was still his usual unhittable self this season, until a freak injury during batting practice resulted in a torn ACL and an uncertain future. Rivera's 2012 season was supposed to be his last, but Yankee fans likely expected an extended farewell tour, where the great Rivera would enjoy a slew of richly deserved accolades as he approached retirement. Rivera's season may be over, but will he let his career end like this?
