CLEVELAND -- Right-hander Kyle Waldrop was activated from the disabled list and optioned to Triple-A Rochester on Friday.
Waldrop, who was placed on the disabled list retroactive to March 26 with a strained right elbow, made four rehab appearances with Class A Advanced Fort Myers.
He tossed four scoreless innings, allowing two hits while striking out five and walking one. He made two appearances in mid-May before returning to Minneapolis to have a precautionary MRI on his elbow on May 21. But the MRI showed no new structural damage and he returned to Fort Myers, where he tossed scoreless innings on Sunday and Tuesday.
"I think he's throwing the ball pretty well," assistant general manager Rob Antony said. "He's throwing strikes. He's been efficient. The main thing is he felt good."
To make room for Waldrop on Rochester's roster, the Twins released right-hander Daryl Thompson. They also released Brad Thompson, who was pitching at Double-A New Britain.
Parmelee thriving in first Triple-A stint
CLEVELAND -- The Twins have been impressed with the way first baseman Chris Parmelee has been swinging the bat since being optioned to Triple-A Rochester on May 15.
Parmelee, 24, entered Friday hitting .452 with three homers, three doubles, nine walks and nine RBIs in nine games.
It's Parmelee's first stint at Triple-A, as he went straight from Double-A New Britain to the Majors last season as a September callup before making the club out of Spring Training this year. He excelled in 21 games last September, hitting .355 with 10 extra-base hits, but struggled in 27 games this year, hitting .179 with six extra-base hits.
"I like him playing right now," Twins manager Ron Gardenhire said. "I like the way he's swinging. He hasn't played any Triple-A baseball, so this doesn't hurt him at all to get Triple-A at-bats right now and get confidence going just like the last time he came up here last year and played the heck out of it."
Parmelee remains an option to be recalled when the Twins play by National League rules in Interleague Play in Pittsburgh and Cincinnati later this month. But with Justin Morneau back at first base, it could be difficult for him to see much playing time unless he plays in the outfield or serves as a pinch-hitter.
"I wouldn't say he's blocked, but if you want Morneau in the lineup, he's got to play first in National League parks," assistant general manager Rob Antony said. "So if we went down and got him, he'd be a pinch-hitter off the bench. ... Once we head into those, we'll talk to Gardy and see what he wants his bench to look like once we head into Interleague Play."
Doumit gets nod behind the plate
CLEVELAND -- Twins manager Ron Gardenhire decided to switch things up on Friday, as Ryan Doumit caught right-hander Carl Pavano for the first time all season.
Drew Butera usually serves as Pavano's personal catcher, but Gardenhire said he wanted to get more offense in the lineup.
"I just want Doumit's bat in the lineup," Gardenhire said. "I want Joe Mauer's bat in the lineup and Justin Morneau's bat in the lineup, so, yeah, Doumit can catch just fine. No problems."
Gardenhire added that Mauer is fine, despite getting hit in the mask by a foul tip in Monday's win against the A's at Target Field.
Mauer made his third straight start at designated hitter on Friday, but Gardenhire said Mauer will be back behind the plate soon and could play first base in one game this weekend.
"I'm giving Joe as many days as I can away from it [catching]," Gardenhire said. "He got beat up, foul tipped all those things, but he's fine. He was ready to catch the other day, he's fine. He's ready to catch. I just wanted to play Doumit. I like this matchup better, play Joe as DH, one of these days Mauer's going to probably play first. The more I can keep him out from behind there, taking a beating, I think the better chance we have of getting deep into the season, him not needing days off."
