The move is retroactive to July 11, meaning Kazmir might miss only one turn in the rotation. The tentative plan is for him to start on July 26 against the Red Sox at Angel Stadium.
"Kaz in his workouts this weekend came out with a little stiffness there, and it's something that just comes up now," said Angels manager Mike Scioscia. "So we have an advantage with where we were with the All-Star break when he last pitched, that we really can push him back and get him out there Monday if everything goes well."
The Angels will wait to announce who will start on Tuesday. Triple-A right-handers Trevor Bell and Sean O'Sullivan are the most likely candidates to get the call.
"We'll have an announcement," Scioscia said. "We'll be bringing somebody up. The rotation will have the extra day."
