Glaus sidelined by strained oblique

Cards slugger tweaked muscle pinch-hitting Saturday

ST. LOUIS -- Troy Glaus was still in significant pain on Monday after suffering a strained left oblique muscle in Saturday's 7-6 loss to the Braves.

Glaus was unavailable on Sunday and Monday, and he likely will continue to be out of service for the foreseeable future. If he had been healthy, he likely would have started in Monday's 11-6 win over Florida, due to his 4-for-6 career mark against Florida starter Ricky Nolasco. Instead, he was held out.

"It still hurts," he said on Monday night. "We'll wait for a little bit, hopefully get a [cortisone] shot and see what happens."

A cortisone shot typically keeps a player out of action for two or three days, beyond any time the injury itself may require. Thus it's difficult to envision Glaus playing before the weekend at the earliest, and oblique injuries tend to be tricky ones, as well.

It's been an extremely frustrating year for Glaus. He underwent shoulder surgery shortly before Spring Training started, and the rehabilitation from that operation took him well into the second half of the season. Then, after he began playing Minor League rehabilitation games, he suffered back spasms that sidelined him once again. He has made 18 Major League plate appearances this year, going 3-for-17 with a walk, a double and six strikeouts.
