MINNEAPOLIS -- An MRI on Tuesday showed Trevor Plouffe to have a "very mild strain" of his left hamstring, according to Twins trainer Rick McWane.
The Twins shortstop felt tightness in his hamstring while scoring from second base in the eighth inning Sunday, and Plouffe was held out of the starting lineup Monday and Tuesday in favor of Matt Tolbert.
"He went out and ran sprints, he said he felt OK," McWane said. "We're just going to see what he can do the next couple days and try to make a decision."
But with all the injuries the Twins have dealt with lately, manager Ron Gardenhire does not want to go too long with Plouffe on the bench and unavailable to play.
One way or another, he expects a roster move after Wednesday's game.
"We can't keep [going] day to day [with] stuff, it's not helping me a bit. We need either 'yes' or 'no'," Gardenhire said. "We'll see where Plouffe is at. Probably a 'yes' or 'no', I'm not going to give it a 'Let's wait and see.'" -- Jordan Schelling
Mauer progressing, but no timetable for return
MINNEAPOLIS -- Twins catcher Joe Mauer participated in his first on-field workout with his teammates on Tuesday at Target Field as part of his rehab process for bilateral leg weakness.
Mauer took soft-toss from hitting coach Joe Vavra on the field and reported that while he's making progress, there's still no timetable for his return.
"We got on the field today, which was good, and I'm feeling a lot better," Mauer said. "I've been hitting off the tee for a couple days, and we got out on the field -- which was good -- and just took some tosses."
Twins manager Ron Gardenhire watched Mauer from center field and said the "ball was jumping off his bat." He added that he expects the next step to be a round of full batting practice, which could come as early as sometime during this five-game homestand that ends Sunday against the Blue Jays.
"It'll be nice to have him out there doing the BP thing with us," Gardenhire said. "That's goal for the homestand, maybe. Just doing full rounds of BP, and then we'll go from there."
Mauer, though, said he couldn't predict whether he'll be ready to take full batting practice in the next few days, as he's still dealing with the soreness in his legs.
"I hope so," Mauer said about taking batting practice this week. "We'll see how I feel tomorrow. It's my first day out on the field, so I'm probably going to be pretty sore tomorrow. So that's [why it's] tough to put a date on when I'm gonna be back, because I don't really know what tomorrow is gonna bring."
Mauer, 28, also said he has yet to do any squatting or catching drills, but that he's getting stronger, especially after gaining back the 15 pounds he lost as a result of the flu that plagued him right around the time he was placed on the 15-day disabled list on April 14.
"It's coming back," Mauer said. "My legs are feeling stronger, so it's good. I'm making good progress, but still got some work to do. Then you've got to get back into baseball shape, things like that. But yeah, I still got some work to do, and I wish I knew when I would be back, and I know everybody else wishes too, but you just go to keep going in the right direction."
Mauer, who signed an eight-year contract worth $184 million in the offseason, also maintained that he wants to return as a catcher, and won't rush to come back as a designated hitter because he wants to be 100 percent healthy, so he doesn't suffer another setback.
"I think I'll come back and catch," Mauer said. "I think that's what they want me to do, and that's what I want to do. It's still May, and I can try and come back and get out there before I'm ready to go and I'd be back where I was a couple of weeks ago. That's what we definitely want to do." -- Rhett Bollinger
Young anticipating Friday return
MINNEAPOLIS -- Left fielder Delmon Young is expected to rejoin the Twins on Friday after going on the 15-day disabled list on April 27 with a strained left oblique.
Young batted five times Tuesday in an extended Spring Training game, collecting three hits and showing that he is healthy enough to play left field in another rehab game Wednesday.
"He got three infield hits, and scored from first," Twins trainer Rick McWane said. "It doesn't bother him to run, it doesn't bother him to swing."
Young is just one of three Twins players currently rehabbing in Fort Myers, Fla. Joining him are second baseman Tsuyoshi Nishioka and designated hitter Jim Thome, both of whom also are making progress with their rehab work.
Nishioka is doing "very light work," according to manager Ron Gardenhire, without much lateral movement.
"Right now, very light activities on the field, under control," Gardenhire said. "It's not like hitting ground balls, fungos all over. Rolling the ball to him, very light."
The soreness that Nishioka had been experiencing in his left leg was reported to be much better Tuesday.
Thome, who has been out since May 1 with a strained left oblique, took batting practice Tuesday. The Twins hope he'll be able to begin rehab games soon as well.
"He's going to take BP again tomorrow," McWane said. "No problems with his oblique, hopefully he'll start playing in games on Thursday." -- Jordan Schelling
Twins players, coaches hold meeting
MINNEAPOLIS -- With all the injuries to key players early this season, the Twins' roster is filled with players that have been called up from Triple-A Rochester.
While the difference in talent level is an obvious result, chemistry and experience bring other issues as well. A number of Twins players and coaches met Tuesday afternoon to address some of those issues.
"Talking baserunning, talking quality of at-bats, situations, you handling the situation rather than it handling you, all those things," manager Ron Gardenhire said. "Last night, we had a lot of opportunities to get a hit, and we were chasing. We were chasing a lot of pitches, and it looked like the situation kind of controlled us.
"We just have to be better. We have to control the situations a little better, and I'm not saying it's easy, but you know what, we have to keep working at it. That's all we can do." -- Jordan Schelling
