DETROIT -- Joe Mauer is unquestionably the Twins' best player and the St. Paul native is the face of the franchise.
So when he was placed on the 7-day disabled list with concussion-like symptoms after Tuesday's game against the Tigers, it raised the question about whether Mauer should continue to be subjected to the daily rigors that come with being a big league catcher.
Eight catchers have been placed on the concussion list this year, including both Ryan Doumit and Mauer. And the Twins are no strangers to the long-lasting effects concussions can have on players, considering what Justin Morneau went through with his season-ending concussion in 2010 that lingered well into the 2011 season.
"I think it's concerning for the entire industry that it's increasingly a hazard at that position," Twins assistant general manager Rob Antony said. "Our best player is a catcher and fortunately he hasn't had issues in the past. You hope this is an isolated thing and not a trend."
Considering it is Mauer's first concussion and signs point to it being minor -- he spent Wednesday at the team hotel and told trainers he's feeling better -- the Twins will continue to keep Mauer behind the plate. But Antony said there could be a day when Mauer is shifted to another position or sees his workload behind the plate decreased dramatically.
"I don't want to overreact to this thing because it's only happened in the last day, but Joe's preference has always been to catch," Antony said. "When you have what we consider to be the best catcher in the game, it's hard to want to move a guy around, but you let a lot of things dictate that. I'm sure at some point in his career you'll want him in the lineup every day and have that bat in the lineup.
"Ironically, this has been one of his best years defensively. He's healthy and throwing way better this year. It's a shame this interrupts that. That's something I'm sure we'll talk about it. And if Joe wants to talk about it, we'll talk about it, but right now it's not something we're thinking about."
Twins manager Ron Gardenhire has also noticed the disturbing trend among catchers with concussions, but said he believes Mauer will fight to remain behind the plate, as it's long been his preference.
But Mauer has seen more action at first base and designated hitter over the last two years, and the Twins will carefully monitor the situation moving forward.
"There's not much you can do about it -- he is one and he's going to be one for a long time," Gardenhire said. "I think we're all starting to see it out in the open now, because we're able to test for this. We're seeing more and more catchers step up. This is pretty serious stuff with what you've seen with all the catchers going down with this."
Deduno remains on track to start Friday
DETROIT -- Right-hander Samuel Deduno threw a bullpen session without any issues on Wednesday, and is slated to make his scheduled start on Friday against the Indians.
Deduno, who has been dealing with right biceps tendinitis, threw in front of pitching coach Rick Anderson, bullpen coach Bobby Cuellar and head trainer Dave Pruemer, and was encouraged by the results.
"I felt pretty normal," Deduno said. "I didn't feel anything. I just want to keep my mind strong."
It was welcome news for the Twins, considering they still haven't named a starter for Saturday's game after optioning right-hander Kyle Gibson to Triple-A Rochester on Monday.
Right-hander Liam Hendriks, who threw eight scoreless in his last start with Rochester, is the front-runner to make that start on Saturday, but the Twins will wait to announce the starter on Thursday.
Long reliever Anthony Swarzak is out of the running to make that start, as he'll be ready for action on Friday in case Deduno falters. Deduno has a 7.02 ERA over his last three starts.
"We have extra pitchers, so if [Deduno] struggles or gets hurt or doesn't feel right, we're covered," Twins assistant general manager Rob Antony said. "But it's a relief. Hopefully, he goes out there and pitches a good game."
• Outfielder Oswaldo Arcia has been taking anti-inflammatory medicine and receiving treatment on his sore left wrist, and was held out of the lineup for a second straight game on Wednesday.
He's a candidate to be placed on the 15-day disabled list if he doesn't get through batting practice on Thursday, according to Antony. Gardenhire mentioned Darin Mastroianni and Chris Parmelee as candidates to be recalled from Triple-A Rochester if Arcia goes on the DL.
• Triple-A Rochester outfielder Aaron Hicks was activated from the Minor League disabled list, but left Rochester's game on Tuesday night after spraining his left wrist diving for a ball in the outfield. Hicks, who was originally out with a sore heel, is expected to be examined further and is likely to go back on the Minor League DL.
• Right-hander Alex Meyer, who is working his way back from a strained right shoulder, was promoted to Double-A New Britain. Meyer made three starts in the Gulf Coast League, posting a 1.08 ERA with 16 strikeouts in 8 1/3 innings.
Meyer, ranked as the Twins' No. 3 overall prospect according to MLB.com, touched 98 mph in his last start in the Gulf Coast League on Monday.
