Indians closer Chris Perez has tendinitis in his right shoulder and will be shut down from throwing for a week.
Perez underwent an MRI in Cleveland on Monday, one day after he felt a ''pinch'' in his shoulder while pitching in the ninth inning of an appearance in Boston. The Indians said the two-time All-Star has ''mild'' tendinitis of his rotator cuff. The plan is for Perez not to throw for at least five days and then be re-evaluated.
Perez blew a three-run lead in Sunday's game.
While Perez is sidelined, Vinnie Pestano will take over closing duties for the Indians, who have lost four straight and six of seven entering Tuesday's game in Cincinnati.
Perez, who was slowed by a sore shoulder in training camp, is 2-1 with a 4.32 ERA and six saves in 16 2-3 innings over 17 appearances.
