Duensing impressing since return to 'pen

MINNEAPOLIS -- Since moving back to the bullpen this month, left-hander Brian Duensing has impressed Twins manager Ron Gardenhire.

Duensing has posted a 1.08 ERA in six appearances dating back to Sept. 2, with four strikeouts and two walks in 8 1/3 innings.

He was especially effective against the White Sox on Saturday, when he threw 3 1/3 scoreless innings and retired the first 10 batters he faced.

"He did a really nice job," Gardenhire said. "Came in, threw the ball over the plate, used all of his pitches, looked really confident and relaxed out there, and got us a few really good innings when we desperately needed them after another starter going four innings."

Duensing has split time between being a starter and a reliever this season, but has fared better out of the bullpen. He has a 2.77 ERA in 48 2/3 innings as a reliever, compared to a 6.92 ERA in 52 innings as a starter.

Mauer, Doumit return to lineup vs. White Sox

MINNEAPOLIS -- Joe Mauer and Ryan Doumit, who both were dealing with injuries this week, returned to the lineup on Sunday against the White Sox.

Mauer, who has been out since Monday with back spasms, started at first base, while Doumit, out since Wednesday with a strained oblique, got the start behind the plate.

"They're all in," Twins manager Ron Gardenhire said. "It's a fun lineup. We got some boys back."

With Mauer at first base, Justin Morneau started at designated hitter and Josh Willingham got the day off.

Day after highlight catch, Revere starts in left

MINNEAPOLIS -- Ben Revere has continued to turn heads with his outfield defense, but started in an unfamiliar spot on Sunday against the White Sox, as he made just his third start of the year in left field.

Revere, who has made 69 starts in right and 32 in center this year, started in left for the first time since April 27. Chris Parmelee got the start in right field because of his lack of experience in left.

But Revere excelled again in center on Saturday night, when he made an over-the-shoulder catch to rob A.J. Pierzynski of extra bases to end the eighth with two runners on.

"It was unbelievable," Twins manager Ron Gardenhire said. "It's highlight stuff. We've seen it quite a bit. It's good stuff. In fact, a great play that kept us in the game."

Revere called it one of the Top 10 catches of his young career, and added he was surprised by how far the ball carried.

"I didn't think Pierzynski hit it that well," Revere said. "But then I heard [Josh] Willingham yell 'back,' so I kind of went back and looked both ways to see where the fence was, and I kind of caught it before it hit the fence. It was a play that had to be made or the game was going to get out of control."
