Sox ponder whether to DL Doubront

NEW YORK -- Red Sox manager Bobby Valentine did not rule out placing left-hander Felix Doubront on the 15-day disabled list retroactively if the team decides against using him until the end of next week.

Doubront, who has not started since Aug. 9, was scheduled to throw a 45-pitch bullpen session Friday, and will throw one more, of longer duration, if all goes well, before he is employed in a game situation. But if the Sox do not add him to the rotation for the Angels series, a DL move could be in the offing, which would allow the Sox to add another player in the interim.

It's possible the Sox are waiting to see whether they make a move with right-hander Aaron Cook, who reportedly was placed on waivers.

The Sox are mindful of Doubront's workload in his rookie season. He has made 22 starts this season and thrown 122 2/3 innings, after throwing just 87 2/3 innings in 2011, including 10 1/3 innings in Boston. The most innings he has ever worked in pro ball was 121 for Double-A Portland in 2009.

"He had a nice active rest period," Valentine said. "He had a little knee situation that we wanted to make sure cleared up. He'll be ready this next week to pitch. If we decide we don't need him until the end of the week, we might even take that amount of time."
