MINNEAPOLIS -- The Twins are one of just a handful of teams who have fared better on the road than at home this season; only six clubs have more wins away than at their home field entering play Friday.
The Twins are just 30-41 at Target Field, while they're 33-41 away from home. Twins manager Ron Gardenhire said he can't figure out why his club has had so many troubles at home this year.
"Wins are wins, but you definitely feel terrible about not winning at home," Gardenhire said. "Our fans come out to support this baseball team, and for us not to let them leave happy -- that's disappointing. We've always said, 'You have to take care of your home.' For whatever reason, I don't understand why we aren't winning here at home, but we have do a better job of that."
It's been part of a disturbing three-year trend for the Twins at Target Field after posting the best home record in baseball in 2010. The Twins went 33-48 at home in '11 and 31-50 at Target Field in '12.
Deduno to undergo arthroscopic shoulder surgery
MINNEAPOLIS -- Right-hander Samuel Deduno will have arthroscopic surgery on his right shoulder on Wednesday, according to Twins general manager Terry Ryan.
The procedure will repair Deduno's rotator cuff, which showed signs of fraying in an MRI exam. Dr. Diane Dahm will perform the operation in the Twin Cities.
"He'll get a cleanup on his shoulder," Ryan said. "It's not a serious surgery, but it's something we think needs to be done."
Ryan said Deduno will need to rehab his shoulder over the next few months, but will be ready for Spring Training next year. Deduno won't pitch in winter ball this offseason.
The 30-year-old right-hander finishes the 2013 season at 8-8 with a 3.83 ERA in 18 starts with 67 strikeouts and 41 walks in 108 innings. He was originally placed on the 15-day disabled list on Aug. 30, before being transferred to the 60-day disabled list on Monday.
Six-man rotation gives arms necessary rest
MINNEAPOLIS -- Scott Diamond officially joined the rotation with his start against the A's on Thursday, and the Twins are expected to go with a six-man rotation for the rest of the way.
As a result, right-hander Kevin Correia started against the Rays on Friday with an extra day of rest.
Twins manager Ron Gardenhire especially likes the idea because of the extra rest it provides to players such as Mike Pelfrey and Andrew Albers, who are having their innings monitored down the stretch.
Pelfrey is coming off Tommy John surgery, while Albers has already thrown a career-high 178 innings between Triple-A Rochester and Minnesota. Albers has fared much better on long rest, with a 0.57 ERA in four starts on five-plus days of rest compared to a 9.42 ERA on the normal four days of rest. Pelfrey has also had more success with more rest, as he has a 6.20 ERA on normal rest and a 4.65 ERA on five-plus days of rest.
"It should help," Gardenhire said. "These guys have a lot of innings for the most part. And we want to see Scottie pitch. And this helps us with Albers and Pelfrey. We're talking about innings with these guys, so it helps to give them an extra day and see how they respond."
Gardenhire added he doesn't have a target shutdown date for either Albers or Pelfrey. Right-hander Cole De Vries remains the club's top option to join the rotation if the Twins do decide to replace one of their starters.
"We're just playing it day by day," Gardenhire said. "We're not ready to say they'll be shut down after this one or that one. We just want to see how they do."
