Adams placed on 15-day DL with strained back

MIAMI -- The Phillies placed right-handed reliever Mike Adams on the disabled list Monday because of a strained back.

The move is retroactive to May 11, meaning Adams can be activated as early as Sunday. But because he has not pitched since May 10, he will need to get his arm back in shape. He said he plans to throw Thursday and Saturday in Clearwater, Fla., and if everything goes well, he said he hopes to be activated before Monday's series opener against the Red Sox in Boston.

"Everything is feeling good," he said. "The pain subsided. It's been a week. I need to get into throwing shape."

Right-hander Justin De Fratus could see more time in the late innings while Adams is out. He has thrown 2 1/3 scoreless innings in four appearances, pitching in some big spots along the way.

"I trust him," Phillies manager Charlie Manuel said.
