Biceps tendinitis has Deduno's status in question
By Rhett Bollinger / MLB.com
DETROIT -- Right-hander Samuel Deduno was diagnosed with right biceps tendinitis and is scheduled to throw a bullpen on Wednesday to determine if he'll be able to make his next start on Friday against the Indians.
Deduno has struggled recently. He had a 3.17 ERA through his first 13 starts this season, but has a 7.02 ERA over his last three starts to see his ERA for the season rise to 3.82.
But he neglected to tell team trainers about his nagging injury until after his last start on Sunday, and so the Twins want to see how he fares on Wednesday before making a decision about his next outing.
"We'll see how he feels and we'll go from there," Twins assistant general manager Rob Antony said. "We'll decide if he'll make his next start on Friday or not. He has some inflammation in there, and some biceps tendinitis. But it's tricky, because he's not giving straight answers on if he can go or not. So we're just going to see how tomorrow goes and make our decision on what we see then."
If Deduno can't make his next start, it will put the Twins in a bind, as they currently don't have a starter for Saturday's game against the Indians with right-hander Kyle Gibson optioned to Triple-A Rochester. Right-hander Liam Hendriks looks to be the favorite to start Saturday, so the Twins could turn to Scott Diamond, P.J. Walters or long reliever Anthony Swarzak for a spot start.
Mauer lands on DL with concussion-like symptoms
DETROIT -- The Twins will be without their All-Star catcher, as Joe Mauer was placed on the seven-day disabled list with concussion-like symptoms after Tuesday's win over the Tigers.
Mauer was a late scratch from the lineup after experiencing dizziness during batting practice. To fill Mauer's spot on the roster, Minnesota recalled first baseman/outfielder Chris Colabello from Triple-A Rochester.
"The Detroit doctor examined him and did some tests and found he had some concussion-like symptoms," Twins assistant general manager Rob Antony said. "For him, it was mainly he felt dizzy and out of sorts. He did the baseline test and they were pretty certain he had the symptoms of a possible concussion. The doctor felt like he should he go on the seven-day DL, and we agreed with that."
Mauer is expected to remain at the team hotel on Wednesday. If he feels well enough, he'll fly back to Minnesota on Thursday. One good sign is that he didn't feel sick while flying to Detroit with the team, which was something that bothered both Ryan Doumit and Wilkin Ramirez before they were both placed on the concussion DL earlier this year.
But Mauer came in with a minor bruise on his forehead after taking a foul tip to the facemask with Mets first baseman Ike Davis at the plate in the seventh inning of Monday's 6-1 loss.
Mauer was slated to start at first base with Justin Morneau at designated hitter, but Morneau shifted back to first with Mauer out of the lineup. Josh Willingham moved from left field to DH while Wilkin Ramirez made the start in left field.
"He said his forehead was sore from a couple whacks, but when he got out there he didn't feel too awful hot so we had him checked out," Twins manager Ron Gardenhire said. "I'm glad we found out before the game, instead of during the game, to protect him."
Twins first baseman Justin Morneau, who is no stranger to concussions after suffering one in July 2011 that ended his season, said he could tell something was wrong when Mauer missed a few grounders at first during batting practice. His advice to his longtime teammate was to play it smart.
"I think it's for the best," Morneau said. "The worst thing that can happen when you have a concussion is to do something unintelligent and not tell anyone and suffer another one and be out a while. The last thing you want to see is somebody that good miss a lot of time."
Mauer has been durable this year, as he ranks second on the team in games played with 113 -- including 73 starts behind the plate. His only significant time missed came when he missed seven games due to the birth of his twin girls in late July.
Sore left wrist keeps Arcia out of opener
DETROIT -- Rookie outfielder Oswaldo Arcia has been dealing with a sore left wrist stemming from a diving play in the outfield on Thursday, and was held out of the lineup against the Tigers on Tuesday.
Arcia, who is day to day, didn't tell team trainers about the severity of the injury and tried to play it through it. But he went just 1-for-9 at the plate since injuring the wrist and finally told head trainer Dave Pruemer about his injury before the series against the Tigers.
"He didn't tell the trainers, so I think Dave was a little upset with him for not saying anything," Twins manager Ron Gardenhire said. "You have to get treatment if your wrist is bothering you. And, obviously, his wrist is still bothering him, but he didn't let anybody know that. So it's a bad way to go about your business. And now I don't know how many days we'll be without him."
Arcia will now get treatment for his wrist, but it leaves the bench thin, as the Twins are carrying 13 pitchers -- including nine relievers -- after recalling right-hander Michael Tonkin from Triple-A Rochester on Tuesday.
"He'll take some anti-inflammatories and will get it worked on, so it's not expected to be a long-term thing," Twins assistant general manager Rob Antony said. "So it's another day-to-day thing. But if we would've known, he could've had treatment."
Twins recall righty Tonkin after Gibson sent down
DETROIT -- The Twins recalled right-handed reliever Michael Tonkin from Triple-A Rochester on Tuesday to take the spot of right-hander Kyle Gibson, who was optioned to Rochester after his start on Monday.
Tonkin, 23, has a combined 2.39 ERA with 60 strikeouts and 13 walks in 52 2/3 innings between Double-A New Britain and Rochester this year. He recorded seven saves at New Britain and 11 at Rochester.
He also made his lone Major League appearance with the Twins on July 11, throwing 1 1/3 scoreless innings against the Rays, when left-hander Caleb Thielbar was on the bereavement list.
Tonkin is regarded as one of the organization's top relief prospects, as he possesses a mid-90s fastball and a hard slider he uses as his out pitch. He showed off his big arm in his Twins debut, striking out Rays star Evan Longoria with a 96-mph fastball.
"It was fun to experience it and see how everything works, like how the clubhouse works," Tonkin said of his time in the Majors. "But I wouldn't say I got a huge taste of it. But to be able to experience it firsthand was nice."
But his stint with the Twins could be a short one again, as the club is without a starter for Saturday's game against the Indians, with Gibson sent down to Rochester.
The Twins could opt to use long reliever Anthony Swarzak in a spot start, or they could call up a starter from Rochester, such as Liam Hendriks, Scott Diamond or P.J. Walters. Hendriks could be the most likely, as he threw eight scoreless innings in his last start on Monday and is lined up to start again on Saturday.
