ARLINGTON, Texas -- Rangers reliever Mike Adams was diagnosed with Thoracic Outlet Syndrome, a condition where a rib bone pushes against a nerve and causes numbness or pain in the arm or shoulder.

Adams was told he needs to rest 7-10 days but said he hopes to pitch through the pain in the playoffs.

Rangers starter Matt Harrison had the same ailment a few years ago and was fine after surgery.

Other notes:

* Manager Ron Washington said he isn't sure what he's going to do about Monday's starter in Oakland, and much if it depends on today's doubleheader.

"We'll see where we are today and who we don't use, and make a decision," Washington said.

Martin Perez made the last start in that fifth-starter spot but isn't the only candidate for that spot. Roy Oswalt could pitch and perhaps give the club some innings. Scott Feldman and Justin Grimm also are possibilities.

* Washington said he can't worry about Adams' situation right now, saying he has to focus on "who we have on board now" as the club tries to clinch things.

* There were costumes hanging in a few lockers of some vets, meaning today is likely the day when the rookie dress up for the flight to Oakland, a baseball tradition.
