On Friday, Indians manager Manny Acta indicated that Perez complained of shoulder fatigue following his latest Minor League outing. An MRI exam performed on the pitcher's arm came back clean, but the team has opted to keep him off a mound for the next few days.
"He had another MRI, but it showed great improvement," Acta said. "We're just going to shut him down for three to five days and then re-address the throwing issues."
Acta said the good thing is Perez will not need to start his throwing program from scratch.
Perez, who has been on the disabled list since April 26 due to a strained left lat muscle, logged two innings for Triple-A Columbus on Monday in his most recent rehab appearance. Overall, the left-hander has pieced together five shutout innings in four rehab games between Double-A Akron and Columbus.
Perez was 1-0 with a 3.52 ERA in eight outings for the Indians earlier this season prior to being sidelined with the injury. The lefty went 5-2 with a 3.00 ERA in 71 appearances out of Cleveland's bullpen last season.
