Lowrie will not need wrist surgery

Lugo could start rehab assignment next week with PawSox

OAKLAND -- Not only did the Red Sox depart the West Coast with a win, but they also got some good news on the injury front.

Shortstop Jed Lowrie, who was placed on the 15-day disabled list on Monday, will not need surgery for his ailing left wrist.

Lowrie was given an encouraging diagnosis from Dr. Thomas Graham -- a hand specialist -- in Baltimore on Wednesday.

Graham treated Lowrie's sprained wrist with a cortisone shot.

"It confirmed the original diagnosis, which is good, so they injected the area at both locations of the discomfort," said Red Sox manager Terry Francona. "He's going to be placed in a splint for about five days before he begins his strengthening."

The Red Sox have both of their starting-caliber shortstops on the disabled list. Julio Lugo underwent right knee surgery in March and could start a rehab assignment at Triple-A Pawtucket on Tuesday.

Lowrie could be back on the active roster in three or four weeks.

"He'll potentially be able to resume baseball activities in a couple of weeks," Francona said. "Maybe we'll get him back in three or four. The news is very good as opposed to what it could have been. After he got his injection, he showed very good strength, which, I think, from what these guys are saying, is a great sign."

Nick Green has started the past four games at shortstop and will continue to hold down the fort until Lugo returns.

Gil Velazquez is serving as the backup.
