OAKLAND, Calif. -- Rangers starter C.J. Wilson said the blister on his left middle finger is fine. He will continue to use the laser treatment on it and is not worried about it.

Neither is manager Ron Washington.

"It's not an issue," Washington said. "The blister had nothing to do with last night. It didn't have anything to do with him missing the strike zone in certain situations."

Wilson gave up two runs on seven hits in six innings in Wednesday's 3-2 win. But he left some pitches up and wasn't quite as sharp as he's been during the second half of the season.

Wilson said he expects to continue with his normal routine as he prepares to start Monday's game against the Angels in Anaheim. If the Rangers have clinched by then, he would pitch only three innings or so just to stay sharp and ready for Game 1 of the ALDS on Friday.

Other notes:

* The club is still waiting for word on Mark Lowe, who went back to Texas to have team physician Dr. Keith Meister check on his left hamstring, which he hurt Wednesday during pregame warmups. They should know more closer to game time today.

* Rangers reliever Mike Gonzalez returned to Texas today because he was sick. Manager Ron Washington said the club didn't want to take any chances that he might get others ill, so he'll get back and rest.

Gonzalez was available in the bullpen on Wednesday and didn't feel ill until after the game. He has worked 2 1/3 scoreless innings in his last two outings.

* The Rangers are not renewing the contract of Mike Boulanger, minor league hitting coordinator. This was his ninth season with the club.
