MINNEAPOLIS -- The Twins on Monday unveiled the "Minnesota Millers" jerseys they'll be wearing Saturday night when they host the Royals at Target Field.

The Twins are hosting a "Turn Back the Clock" game and will be wearing throwback uniforms of the 1951 Minneapolis Millers. The Royals will be donning throwback uniforms of the Kansas City Blues.

Josh Willingham, Brian Dozier and Drew Butera helped model the throwback uniforms before Monday's game against the White Sox.

Named for the city's flour milling heritage, the Minneapolis Millers played in Minnesota from 1884-1960 as a Minor League team.

"While generations of residents may not even be aware of the Minneapolis Millers, or that a 4,000-seat ballpark once stood at 31st and Nicollet, we're proud to celebrate and remember this important time in Minnesota baseball history," said Clyde Doepner, Twins curator. "The Minneapolis Millers stoked the fires of America's burgeoning new pastime at the turn of the 20th century and for more than six decades, this area was a hotbed for great baseball featuring many of the greatest players the game has ever known."

Notable players who donned the Millers uniform include Ted Williams, Willie Mays and even Babe Ruth, even though it was for only one game.

Capps eyes mid-July return from disabled list

MINNEAPOLIS -- Twins closer Matt Capps, who was placed on the 15-day disabled list with inflammation in his right shoulder on Monday, said he was relieved to hear there was no structural damage in his shoulder.

Capps experienced a setback in his one-inning stint against the Reds on Saturday after being held out of action for a week because of the inflammation in his pitching shoulder.

He feared it was something worse but was happy when he received the results from his MRI exam taken over the weekend. He said he's scheduled to get a cortisone shot on Monday or Tuesday.

"Today was a pretty good day," Capps said. "I was a little uneasy about what to expect. I got some good news that it's just inflammation and things like that. So it'll be mostly ice and rest for the next couple days and we'll go from there."

Capps said he plans to start throwing again by the end of the weekend with the hopes of going out on a rehab assignment during the All-Star break and rejoining the team in mid-July. He's eligible to come off the DL on July 9, but the Twins are off from July 9-12 before hosting the A's on July 13.

With Capps out, the Twins will continue to use left-hander Glen Perkins and right-hander Jared Burton as co-closers.

"We'll mix and match," Twins manager Ron Gardenhire said. "Whoever in the eighth inning doesn't pitch in a situational [role] is going to close it. It's nice to have to two guys who can throw the ball like that and make pitches when they need to."

Lefty Robertson earns first big league callup

MINNEAPOLIS -- Left-hander Tyler Robertson, who was recalled from Triple-A Rochester on Monday with closer Matt Capps going on the disabled list with shoulder inflammation, said he's excited about the chance to make his Major League debut.

Robertson, 24, posted a 3.77 ERA with 33 strikeouts in 28 2/3 innings in 33 relief appearances for the Red Wings to earn his first callup to the big leagues.

He said he was told of the decision after Rochester's game on Sunday, as Red Wings manager Gene Glynn held a team meeting to give him the good news.

"It was pretty exciting," Robertson said. "I kinda figured there would be a move made and some guys we're trying to figure out who it was going to be. A couple guys said they thought it was going to be me, but I didn't want anybody to jinx it."

Robertson is now the second lefty in Minnesota's bullpen, joining Glen Perkins. But with Perkins serving as a co-closer, along with right-hander Jared Burton in Capps' absence, Robertson could be used in a situational role against lefties.

"You always say you'd like to break him in a bit and get an easy situation, but that gets thrown out the window when you need him to face a lefty like Adam Dunn," Twins manager Ron Gardenhire said. "He's gotten lefties out down in the Minor Leagues and that's why we brought him up here. He's a bulldog."
