ANAHEIM -- Rangers pitcher C.J. Wilson is dealing with a nasty blister on his left middle finger that hasn't been helping his pitching the past couple of weeks.
"I'm just throwing with my index finger instead of two fingers," Wilson said. "It has been that way for a couple of weeks and I've been trying to make adjustments."
Wilson has a 0.79 ERA in September and officially has not allowed a run in his past 8 1/3 innings and nine appearances. But he failed to retire any of the three hitters he faced on Sunday against the Rays and it contributed to a three-run inning.
Wilson has pitched in 32 games since the All-Star break, tied for the third most in the American League. He is tied for sixth with 71 appearances on the season.
He wants to keep pitching to the end.
"We're trying to make a push," Wilson said. "I asked for a day off last week and I got a day off. If my finger is the only problem I'm having at this point of the season, that's relatively good.
"There are a lot of guys here playing through a lot worse than their finger. Right now nobody cares what hurts on your body. You just keep playing."
Wilson said the blister mainly affects his four-seam fastball.
"Throwing with one finger affects your grip strength," Wilson said. "I can't put much velocity on the ball right now."
Rangers relievers went into Monday's game with an 8.10 ERA in their past eight games, having allowed 21 runs in 231/3 innings.
