Mark Lowe injures hamstring in warmups

OAKLAND, Calif. -- As the Rangers went through their pregame warmups on Wednesday, Mark Lowe injured his left hamstring. Lowe will head to Texas on Thursday morning to have the hamstring looked at by Dr. Keith Meister to get a sense of the severity of the injury. It's possible he could have an MRI.

Lowe, who has retired all five batters he faced in his last two outings, is 2-3 with a 3.89 ERA this season. He has a 2.75 ERA in his last 24 games beginning July 5 and has permitted just three of his last 14 inherited runners to score.

"We'll just have to wait and see what the doctor says," manager Ron Washington said after the Rangers' 3-2 win over the A's.
