DETROIT -- Twins closer Matt Capps is scheduled to throw his first bullpen session on Saturday, and could make two rehab appearances in Florida next week if all goes well.

Capps, on the disabled list retroactive to June 24 with inflammation in his right shoulder, could make a rehab outing in the Gulf Coast League on Monday, or could decide to throw another bullpen session instead.

Either way, the right-hander is scheduled to make a one-inning outing on Wednesday with Class A Fort Myers, with the hope that he'll be ready to rejoin the Twins on July 13 after the All-Star break.

"Saturday's [bullpen session] will determine whether he wants to throw in a game on Monday or throw a [bullpen session]," Twins assistant general manager Rob Antony said. "And it doesn't really matter either way, to be honest with you."

Capps has a 3.42 ERA with 14 saves in 27 appearances this season. He initially felt discomfort in his shoulder against the Brewers on June 15 and took a week off before suffering a setback in an inning against the Reds on June 23.

Twins bring up Deduno to make Saturday start

DETROIT -- The Twins purchased the contract of right-hander Sam Deduno from Triple-A Rochester after Thursday's game against the Tigers, and he's scheduled to start against the Rangers on Saturday.

The Twins optioned first baseman Chris Parmelee to Triple-A to make room for Deduno on the roster. Parmelee, 24, has hit .194 with two homers in 38 games with the Twins this season.

Deduno had been solid at Rochester this season, compiling a 2.14 ERA with 46 strikeouts and 22 walks in 42 innings.

He last pitched on Monday, when he allowed two unearned runs on five hits over seven frames against Pawtucket. The 29-year-old has some Major League experience, with a career 3.18 ERA in a combined 5 2/3 innings with the Rockies (2010) and Padres (2011).

The Twins needed a starter this weekend after right-hander Nick Blackburn was optioned to Rochester on Wednesday.

Blackburn was slated to start Sunday, but right-hander Cole De Vries will start in his place. De Vries was originally scheduled to start Saturday but saw his start pushed back a day because he threw two innings in relief in Wednesday's 5-1 loss to Detroit.

Deduno will be the Twins' 11th starter this season, which is the most in the American League. Minnesota used nine starters all of last year.

Fien excited to join Twins' bullpen corps

DETROIT -- Reliever Casey Fien, who was recalled from Triple-A Rochester on Wednesday, joined the Twins on Thursday and said he's ready to pitch out of the bullpen.

It was a homecoming of sorts for Fien, who was originally drafted by the Tigers in 2006 and posted an 8.36 ERA in 14 innings over parts of two seasons with Detroit from 2009-10.

"It's surreal," Fien said. "I called my wife and said, 'Guess where I'm going? Detroit.' And she said, 'What? You got traded?' And I said, 'No. Not again.' So it was really cool getting that call, especially here."

Fien bounced around before the 2010 season, as he was selected off waivers by both the Red Sox and Blue Jays but ended up rejoining the Tigers that spring.

The right-hander impressed this past Spring Training with the Twins, posting a 1.91 ERA over 9 1/3 innings. And Fien had a 4.30 ERA with 42 strikeouts and 14 walks in 46 innings with Rochester.

"The arm feels good," Fien said. "The velocity is getting back. I'm attacking the strike zone. I'm not walking many guys. I'm letting them hit the ball, if they can."

Dozier, Gardenhire meet to discuss rookie's play

DETROIT -- Twins manager Ron Gardenhire had a 20-minute meeting with shortstop Brian Dozier before Wednesday's game to talk about the rookie's progress so far this season.

Dozier, the organization's Minor League Player of the Year last season, has mixed his good with the bad in his first big league season.

The right-handed hitter is batting .235 with three homers, eight doubles and a triple in 51 games. He's also made 11 errors, which is tops among American League shortstops.

"I've had some ups and downs since I've been up here," Dozier said. "[Gardenhire] assured me that a lot of rookies struggle when they get up, but I think he's been seeing a lot of my offensive struggles taken out to defense. Not necessarily making an error here or there; I can live with that. But being mentally there every single pitch, or taking the ground balls before the inning starts -- anything, really."

Gardenhire said Dozier needs to continue to work on his positioning defensively and reminded him not to get too complacent with his role as the club's everyday shortstop.

"I told him what we see and what he needs to do better to make it easier on himself," Gardenhire said. "Those are the types of conversations we like to have. Young players have things to learn, and a lot of things to work on. And just because you're the top shortstop prospect in our organization, it doesn't mean there's not another one right [behind] you. If you don't keep the fire and don't keep pushing, somebody else is going to come up here, and we're going to be saying this is our future."
