Plouffe activated from disabled list

MINNEAPOLIS -- The Twins activated Trevor Plouffe from the 15-day disabled list after their 4-0 loss to the Tigers on Friday night. To make room for Plouffe on the active roster, the Twins optioned catcher Chris Herrmann to Triple-A Rochester.

Plouffe, who was on the DL retroactive to May 28 with a strained left calf, played in his fourth rehab game with Triple-A Rochester on Friday night. He went 2-for-5 to finish his rehab assignment 5-for-15 with a homer.

Plouffe hasn't played with the Twins since May 21, when he suffered a concussion after being kneed in the head by Braves second baseman Dan Uggla while trying to break up a double play. He was subsequently placed on the 7-day concussion disabled list and was activated on May 29 but suffered a strained left calf while warming up before the game.

Plouffe will take over regular duties at third base, as Jamey Carroll and Eduardo Escobar saw time there in his absence.

Herrmann played in seven games, hitting .462 (6-for-13) with one homer and a double in just his second career stint in the big leagues.

Guardado, Mee inducted into Twins Hall of Fame

MINNEAPOLIS -- Former closer Eddie Guardado and former director of public relations Tom Mee were officially inducted into the Twins' Hall of Fame in a pregame ceremony before Friday's game against the Tigers at Target Field.

Guardado, 42, pitched in the Majors for 17 years, including 12 with the Twins. The left-hander had a 4.53 ERA with Minnesota and registered 116 saves, including a career-high 45 in 2002, when he led the American League.

"I've been nervous for about a month, to be honest with you," Guardado said. "It's a great honor. There's no question about that. I think it's 26 that are inducted, and the names that are inducted -- it's pretty special. It doesn't get any better than that."

Guardado is the Twins' all-time leader in games, appearing in 648, while recording at least 60 appearances in eight different seasons. The two-time All-Star became the Twins' closer from 2001-03 and helped lead the club to two AL Central titles.

Tigers outfielder Torii Hunter played alongside Guardado in Minnesota and was happy to see his former teammate join the Twins Hall of Fame.

"His arm was strong and he wanted to take the ball anytime they gave him a chance and that's why we called him 'Everyday Eddie,'" Hunter said. "He was always ready to go."

Guardado was elected by a 56-member committee consisting of local and national media, club officials, fans and past elected members, using rules similar to those necessary for election to the National Baseball Hall of Fame in Cooperstown, N.Y.

"He had no fear and we always made a lot of jokes that if you're throwing 87-88 mph you should have fear, especially closing out games," said Twins manager Ron Gardenhire. "But he was so competitive."

Mee was elected through the Veterans Committee ballot, which consists of 18 voters. He began his career in 1957 -- four years before the Twins moved to Minnesota -- and is widely regarded as the organization's first employee.

He had many roles within the organization, including serving as the club's backup radio and television announcer and public address speaker. He was most well-known for his role as Director of Media Relations, a position he held for 30 years. The St. Paul native received the Robert O. Fischel award for Public Relations excellence in 1988 before retiring in '91.

"It means a great deal," Mee said. "It's good to be alive, but it's even better to know people know you're still alive. I just had a job. I didn't go to work every day, I went to my hobby. That's what was great."

Ramirez continues recovery from concussion

MINNEAPOLIS -- Outfielder Wilkin Ramirez, who is on the 7-day concussion disabled list, has progressed to baseball activities and said Friday he's feeling much better.

Ramirez, who suffered his concussion in a collision with fellow outfielder Josh Willingham on May 25, has been taking batting practice with the team. He's also been doing running drills and said he's making good progress.

"I'm feeling good," Ramirez said. "I took BP on the field already and I'll do some baserunning and some stretching."

Twins general manager Terry Ryan said Ramirez will head out on a rehab assignment once he feels good enough to play in a game. But Ryan said the Twins still haven't decided when or where Ramirez will go.
