Sox go with Lowrie, unsure about Baldelli

Club to monitor outfielder's injury until Thursday's deadline

ANAHEIM -- The Red Sox have settled on Jed Lowrie as their backup middle infielder for the American League Division Series against the Angels, which starts on Thursday at 9:37 p.m. ET. However, the fate of outfielder Rocco Baldelli, who suffered a left hip injury on Friday night, is still uncertain.

Baldelli continues to be aggressive in treating the injury, and the Red Sox will likely wait until the last minute -- rosters are due at 1 p.m. ET on Thursday -- before making a decision.

Because of the threat Baldelli poses from the right side, Boston would love to have him available for Games 3 and 4, when lefties Scott Kazmir and Joe Saunders are starting for the Angels.

"He's still pretty tender," said Red Sox manager Terry Francona. "I think we plan on taking a full allotment of time just to see if he's OK because of the threat he presents from the right side. I don't know if it will work or not. We're not going to put him on if he can't play, but if he can, we'd like to have him."

If Baldelli can't go, Brian Anderson is likely to win that spot. Joey Gathright is also expected to be one of Boston's reserve outfielders, but his main role will be as a pinch-runner.

As for Lowrie, his surgically repaired left wrist is still not 100 percent, and he experiences inflammation when he has too many at-bats left-handed. But after hitting a grand slam from the left side on Sunday, he reinforced that he can give the team enough to warrant a roster spot.

Nick Green, the team's other backup shortstop, hasn't played since Sept. 16 because of a disc issue.

The Red Sox brought Minor League shortstop Gil Velazquez to Anaheim just in case Lowrie has a setback before the series starts.

"He's been here before," Francona said of Velazquez. "He understands what's going on. We didn't want to get caught short."

Francona still hasn't revealed whether the Red Sox will carry 10 or 11 pitchers, which has put arms like Paul Byrd and Manny Delcarmen on the bubble.

Delcarmen, who has struggled mightily in the second half, got in a car accident on Saturday, leaving his back and neck stiff and sore.

"We'll take inventory of where everybody is," Francona said. "I think we all know how we feel about everybody. We just want to let it fall at its own pace."
