MINNEAPOLIS -- Right-hander Cole De Vries will be recalled from Triple-A Rochester to start Saturday night's game against the Royals, the club announced Friday.
Left-hander Scott Diamond will start the first game of Saturday's doubleheader against Kansas City at Target Field.
De Vries pitched for Triple-A Rochester on Monday, allowing two runs on six hits over eight innings against Charlotte. He is 3-5 with a 4.37 ERA in 12 starts with Rochester this season, including a 2.53 ERA over his last three outings.
"I really feel like I'm pitching pretty well right now, so [I had] more time to get everything tuned up," De Vries said of his time with the Red Wings. "For me, that's more what it was."
Under a clause in the new Collective Bargaining Agreement regarding doubleheaders, the Twins can call up De Vries on Saturday without making a corresponding roster move.
De Vries, 27, made three starts with the Twins this season -- going 1-1 with a 4.20 ERA -- before being optioned back to Triple-A on June 7.
"I feel a little more comfortable with the situation because last time there were a lot of firsts going on and it's kind of a roller coaster of emotions," De Vries said. "I've been through a lot of those first situations now; second and third situations are a little easier to manage."
Righty Waldrop recalled, joins bullpen
MINNEAPOLIS -- Kyle Waldrop is finally where he anticipated being -- in the Twins' bullpen.
The right-hander was recalled from Triple-A Rochester after Wednesday's 12-5 loss to the White Sox. He was expected to be made part of the 'pen after Spring Training, but a right elbow strain in late March derailed those plans. He began the season on the disabled list.
"It feels good," Waldrop said. "It's been a crazy year. Been all over the place. It was bittersweet being up here the first of the season. It was fun being up here, but terrible in the situation being on the DL. It made my drive that much harder to get back and obviously this is where you want to be. It was a lot of hard work and it was a process with the rehab that I had to go through."
Waldrop made his first rehab appearance with Class A Fort Myers in mid-May, but was shut down after experiencing soreness in that right elbow. He was activated June 1 and has since thrown 14 1/3 innings, recording a 1.26 ERA.
Most importantly, his elbow felt fine.
"There was a stretch where I threw four out of six days, that was kind of turning the corner mentally, because I knew I could do it," he said. "And getting out there as much as I was helped me get my feel back for pitches. I was a little sharper those days, even the second and third day I was throwing, I was starting to feel better."
Minnesota manager Ron Gardenhire said he will likely use the sinkerballer in the sixth and seventh innings.
"It was unfortunate that he got hurt," Gardenhire said. "I'm excited to see him get back out there healthy and see what he can do."
Waldrop saw his first action in the Twins' 4-3 loss to the Royals on Friday night. The right-hander tossed 1 1/3 scoreless innings in relief.
Twins sign Doumit to two-year extension
MINNEAPOLIS -- The Twins signed catcher Ryan Doumit to a two-year extension through the 2014 season, the club announced Friday. The extension is worth $7 million, and Doumit will make $3.5 million per year in '13 and '14.
Doumit, who joined the Twins this season on a one-year deal worth $3 million after playing seven seasons with the Pirates, said he was excited to remain in Minnesota for the next two years.
"I knew I wanted to, essentially Day 1," Doumit said. "The last couple days it was brought to my attention they were interested in bringing me back, which was very flattering obviously. The feeling was mutual. I called my agent. I said 'Let's get something done.' I love being here. It's a great situation for me. It's a great clubhouse. There's a great group of guys here. I'm excited to be here. There's no doubt in my mind we're gonna right this ship and I'm glad to know I'll be aboard when we do."
Twins general manager Terry Ryan said the club wanted to keep Doumit because of his ability to serve as a backup to Joe Mauer while also providing offensive production and versatility.
"We did it because he's the ideal guy who can complement some of our guys on our roster," Ryan said. "He seems like a good fit for this club. He's here early. He's good in the clubhouse. Knock on wood, but he's been durable. He's got versatility. He's in the right league for sure. He has some sock in his bat. I guess all the reasons we signed him in the first place graduated to keeping him around here."
Doumit, 31, is hitting .271 with a .332 on-base percentage and .433 slugging percentage in 59 games. He also has seven homers and 32 RBIs in 203 at-bats.
He's seen action at catcher, in right field and as a designated hitter this year. He also played three innings at first base.
"My goal is going to be similar to what it is now," Doumit said. "Catching a bit here and there, DH a couple here and there and outfield is always an option for me. So I'll bring my 19 gloves with me and keep working whenever I can get in the lineup."
Doumit is a career .271/.334/.442 hitter with 74 homers and 298 RBIs in 670 games.
"I'm happy for him," Twins manager Ron Gardenhire said. "He's a worker. He grinds it out. He can play some outfield. He puts some nice swings on the ball. He's been big for our ballclub."
