MINNEAPOLIS -- The Twins made a few roster moves after Wednesday's 5-1 loss to the Tigers, activating reliever Anthony Swarzak from the 15-day disabled list and optioning relievers Jeff Manship and Luis Perdomo to Triple-A Rochester.

The Twins will announce a corresponding roster move prior to Friday's game against the Mariners. But Twins manager Ron Gardenhire said it won't involve another pitcher.

"We're going to go to that extra position player on the bench and go to 12 players," Gardenhire said. "So we'll go from there and see how the road trip goes along."

Swarzak was on the DL retroactive to July 25 with a mild right rotator cuff strain. He last pitched on July 24, when he gave up two runs in one inning against the White Sox in Chicago. But he threw his latest bullpen session on Tuesday and reported no problems.

Manship pitched well on Wednesday, throwing three scoreless innings, but has a 7.89 ERA this year in 21 2/3 innings covering two stints with the Twins.

Perdomo posted a 1.50 ERA in six innings with the Twins, but he had trouble locating the ball, with seven walks in six innings.

The Twins didn't announce which position player they'll recall Friday, but first baseman Chris Parmelee remains the most likely to be called up. He entered Wednesday hitting .354/.470/.691 with 15 homers and 41 RBIs in 49 games with the Red Wings.

Florimon bringing strong glove to Twins

MINNEAPOLIS -- Infielder Pedro Florimon was active on Wednesday after having his contract selected from Triple-A Rochester on Tuesday night, but he wasn't in the starting lineup because he wasn't scheduled to arrive at Target Field until shortly before game time.

It's Florimon's second time in the Majors. He played in four games with the Orioles last season as a September callup, going 1-for-8 with a double while making two starts at shortstop.

"He's your typical slick-fielding infielder," Twins manager Ron Gardenhire said. "He can really pick it. In Spring Training, he had the best hands of anyone in camp. He's done pretty good and is a switch-hitter but is more of a defensive-wiz guy. This will be a good experience for him."

Florimon, 25, was claimed off waivers by the Twins over the offseason. He started the year at Double-A New Britain, where he hit .283 with two homers and four doubles in 30 games before moving up to Triple-A. He batted .251 with three homers, 16 doubles and four triples with the Red Wings and was an International League All-Star.

But defense is Florimon's calling card. He's primarily a shortstop but has also seen time at second base. Gardenhire said Florimon will see action in the middle infield along with Jamey Carroll and Alexi Casilla after shortstop Brian Dozier was optioned to Triple-A Rochester on Tuesday.

"He'll play," Gardenhire said. "I don't wait to sit him too much. So he'll be part of the mix."

Walters, Gibson make Minors rehab starts

MINNEAPOLIS -- Right-handers P.J. Walters and Kyle Gibson both fared well in rehab starts in the Minor Leagues on Tuesday.

Walters, on the disabled list since June 14 with right shoulder inflammation, tossed 2 1/3 scoreless innings with Triple-A Rochester. He gave up two hits and a walk while striking out three. He threw 41 pitches, with 24 going for strikes.

Gibson, who is coming off Tommy John surgery in November, made his first rehab start with Class A Advanced Fort Myers. Ranked No. 6 on MLB.com's Top 20 Twins Prospects, Gibson gave up one run on three hits and a walk over three innings.

It came after he posted a 2.45 ERA with 16 strikeouts in 14 2/3 innings over nine appearances in the Gulf Coast League.

Right-hander Carl Pavano, meanwhile, had his start with the GCL Twins rained out on Monday, and will make a rehab start with Class A Fort Myers on Thursday. He's been on the disabled list since June 4 with right rotator cuff weakness.

Span set to play catch, test shoulder

MINNEAPOLIS -- Twins center fielder Denard Span was held out of the lineup for a third straight game Wednesady, three days after injuring his right shoulder while attempting to make a diving catch.

The Twins remain hopeful Span will be able to avoid the disabled list, but he has yet to swing the bat since suffering the injury. He visited a chiropractor on Tuesday.

"He's getting his treatment," Twins manager Ron Gardenhire said. "He's supposed to stand in on some bullpens and play some catch today."

With Span out, Ben Revere made his third straight start in center field, with Darin Mastroianni starting in right field for a third consecutive game.
