NEW YORK -- Mariano Rivera was hurt playing center field during the Yankees' Old-Timers' Day Game on Saturday and former teammate Roger Clemens said baseball's career saves leader sustained an Achilles tendon injury.
In his lone at-bat, Rivera singled off former teammate Andy Pettitte and easily ran to first base. During an at-bat by Willie Randolph, Rivera took a step and fell to the ground in shallow center field behind second base.
The Yankees did not have an immediate update following their 5-4 win over the Astros.
During an interview with WFAN broadcaster Suzyn Waldman, Clemens said Rivera hurt his Achilles tendon.
