CINCINNATI -- Twins reliever Matt Capps suffered a setback after Saturday's one-inning appearance against Cincinnati and was placed on the disabled list Monday because of right shoulder inflammation.
The Twins recalled left-hander Tyler Robertson from Triple-A Rochester to replace Capps on the 25-man roster. In 33 relief appearances for the Red Wings, Robertson went 2-2 with two saves and a 3.77 ERA while striking out 33 batters in 28 2/3 innings. Robertson, who was drafted by the Twins in the third round of the 2006 First-Year Player draft, will be looking to make his Major League debut.
The Twins will use left-hander Glen Perkins and right-hander Jared Burton as co-closers. Perkins got his second save of the season in Friday night's 5-4 win against the Reds.
Capps hadn't pitched in a week due to the inflammation when he came on in the eighth inning of Saturday's 6-0 loss to the Reds at Great American Ball Park. He allowed one unearned run on one hit and one walk. He also struck out one batter while throwing 23 pitches.
Capps told manager Ron Gardenhire Sunday morning that the inflammation and soreness had returned.
"We gave him, what, a week? We basically pushed him out for a week and that's about as long as you can wait," Gardenhire said. "He said he felt great, but the big test was coming out today. That's what happened the last time he threw, he came in the next day and was really sore. Same thing. He said he was sore in his shoulder."
Capps is 1-4 with a 3.42 ERA and 14 saves in 27 appearances.
"We'll probably do what we've been doing. It's worked out OK," Gardenhire said. "I think you should wait until that bullpen door opens. We're not going to sit here and say, 'This guy is going to close.' We're not ready to do that. And, before we do that, I would tell them first."
Duensing to remain in starting rotation
CINCINNATI -- Brian Duensing will remain in the Twins' rotation, but just when he'll get his next start is still up in the air. Manager Ron Gardenhire said Sunday that no decision has been made yet on who will be starting for the Twins when they host Kansas City in a four-game series at Target Field beginning Friday.
Francisco Liriano, Liam Hendriks and Nick Blackburn are scheduled to start against the White Sox when the Twins open a seven-game homestand Monday. The Twins have an off-day on Thursday before the Royals come to town for a series that includes a doubleheader on Saturday. Duensing's turn in the rotation would come up on Friday, but as he attempts to convert back to a starting role from the bullpen, the Twins are still attempting to prepare him for longer outings.
"He is going to start, but we're just figuring out our days," Gardenhire said. "We haven't set or written it in stone yet what days, but we're definitely going to keep Brian in the rotation."
Duensing threw 63 pitches in three-plus innings of work during Saturday's 6-0 loss against the Reds. He hadn't gone past three innings or thrown more than 45 pitches in any of his previous 30 outings this season. He gave up just one hit and walked one through the first three innings before tiring in the fourth and giving up four runs on three hits, including a two-run home run to Cincinnati second baseman Brandon Phillips.
With Carl Pavano and P.J. Walters both on the disabled list -- Pavano with a shoulder strain and Walters with shoulder inflammation -- the Twins will be looking to add another starter to the rotation in time for next weekend.
Twins assistant general manager Rob Antony said Sunday that Pavano is expected to begin a throwing program this week. Walters is expected to throw a couple of bullpen sessions this week, but will need at least one rehab start before returning to the rotation.
There is no word on Pavano's status. He has asked Gardenhire not to comment on his rehab progress. Walters will likely need at least one rehab start before returning to the rotation.
"He needs to go start and see if he can get through some innings before we can put him back on the mound," Gardenhire said of Pavano. "I can't afford to have him start a game and then go, 'This isn't working out,' and me take him out in the third inning. I can't afford that up here right now. I don't have enough pitching for that."
Morneau in, Span out of Sunday's starting lineup
CINCINNATI -- Denard Span got Sunday off from the starting lineup while Justin Morneau was back in against the National League Central-leading Cincinnati Reds.
Ben Revere made his fourth start of the year in center field in place of Span, who has played in 64 of Minnesota's first 71 games this season. Span was hitting .280 entering Sunday, but had just three hits in 21 at-bats during the first five games of this six-game road trip to Pittsburgh and Cincinnati. Revere led off Sunday. He went 4-for-4 in Friday's 5-4 win against the Reds, but was hitless in four at-bats during Saturday's 6-0 loss.
Darin Mastroianni started in right, Revere's normal position, and batted second.
Morneau was back at first base after sitting on Saturday. Joe Mauer made his his first appearance at catcher since last Sunday when he suffered a bruised right thigh on a collision with Milwaukee's Rickie Weeks at home plate.
Alexi Casilla started at second base in place of Jamey Carroll.
"We've got to use all of our guys," manager Ron Gardenhire said. "You can't just have guys sitting around doing nothing and then stick them in a ball game when they haven't played in a week. It just isn't right."
