Roberto Pérez heard his left hamstring pop rounding second base trying to go first to third on a base hit at Great American Ball Park.
While he hoped it was a tweak, he quickly accepted the reality.
"I'd never been in so much pain ever before," Pérez said at his locker at PNC Park Monday, hoisted up by a pair of crutches. "I knew right away something was wrong."
After several weeks of getting doctors' opinions and imaging, Pérez underwent surgery to his left posterior thigh to repair a ruptured hamstring tendon, ending his season.
