Healthy Burton displaying confidence

CHICAGO -- Finally healthy after a hyperthyroid condition and shoulder surgery cut Jared Burton's two previous seasons short, the Twins reliever is drawing comparisons to Matt Guerrier from manager Ron Gardenhire in 2012.

Burton hasn't allowed a run in his last 13 appearances, and he's allowed just one run in his last 20 appearances, boasting a 2.35 ERA.

"He's thrown the ball fantastic," Gardenhire said. "He does remind me an awful lot of Matt Guerrier. One of those guys who's not able to throw the ball as many innings as Matty, but the look and the feel and the confidence he has out on the mound, he reminds me a lot of the way Matty went about the game."

Burton's debut season as a Major League reliever for the Reds went well in 2007, finishing with a 2.51 ERA. He followed that with a 5-1 record and 3.22 ERA in 2008.

His tenure with the Reds ended after throwing just 3 1/3 innings in 2010 and 4 2/3 innings in 2011 because of injuries.

"We knew going in what we were doing with him, coming off an arm injury like he's had," Gardenhire said. "We said from the get-go we were going to be careful and kind of help him get through it and give him his days off as needed."

Vavra's advice helping Doumit drive the ball

CHICAGO -- The Twins' Ryan Doumit went without a home run in 20 straight games before roping three long balls in his last two games entering Tuesday to bring his season total to 10.

Doumit said the recent success is a combination of being in a groove at the plate and tweaking his batting stance.

"I owe a lot to Joe Vavra, our hitting coach, who kind of addressed some things he had noticed in my stance as to what could be preventing me from really driving the ball," Doumit said. "It's something we've been working on the last couple days, and it's been paying off in the game."

Doumit didn't share what he and Vavra worked on specifically. Even when he wasn't going deep, Doumit was in a groove. He batted .350 with four home runs and 16 RBIs in his previous 27 games.

He said his offensive contributions are necessary to stay in a lineup that can feature as many as three position players who play catcher.

"It's great that we're versatile enough to play other positions, with Joe [Mauer] at first and catching and DH, and myself playing a little bit of outfield," Doumit said. "We get a chance to not only keep our legs fresh so we can go out there and play every day, but also keep our bats in the lineup."

Club waiting to determine Plouffe's status

CHICAGO -- Trevor Plouffe's bruised right thumb is still keeping him out of the lineup. Manager Ron Gardenhire said he'll wait another couple days before determining if a roster move has to be made.

"We have to get him out and let him take some swings, but he's not ready to do that yet," Gardenhire said. "The area's good, a lot better, smaller area. We just go day by day, he's taking medication for it now, they changed that to stronger stuff, and we'll see what happens."

Gardenhire said after talking to team doctors that it's possible Plouffe may be ready to return Friday. The Twins have an off-day Thursday.

Worth noting

• General Manager Terry Ryan said Carl Pavano will throw a bullpen session on Wednesday. If that goes well, he'll travel to Fort Myers, Fla., and throw another bullpen session there.

• Jamey Carroll recorded his 900th career hit Monday night.

"It's something more so after the fact when you're done playing that you look at those things," Carroll said.

• Twins manager Ron Gardenhire said Justin Morneau, who was reinstated from paternity leave on Tuesday, would be the designated hitter against the White Sox, because he had a stiff neck.

"I think he slept in a bad bed last night," Gardenhire said, "or slept wrong in a good bed."

Morneau went 2-for-4 with a double in Tuesday's 11-4 loss.

• The Twins grounded into five double plays Monday and have grounded into 99 this season, tied with the Orioles for the most in baseball.
