Samuel Deduno (shoulder) has already thrown 6-8 bullpen sessions at the Twins' spring training complex. Deduno underwent arthroscopic shoulder surgery back in September, but he's entering camp at 100 percent. The right-hander will compete this spring for the final spot in the Twins' rotation.

Sam Deduno (shoulder) is playing catch at the club's facility in Fort Myers, Fla. "His rehab from shoulder procedure is on track for him to open spring camp on time," reports Mike Berardino of the St. Paul Pioneer Press. Deduno was shut down for the season in August and underwent arthroscopic shoulder surgery in September. He will compete for a back-end slot in Minnesota's rotation this coming spring.

Samuel Deduno will undergo arthroscopic shoulder surgery on Wednesday. Deduno has already been shut down for the season due to fraying in his right labrum and rotator cuff, and surgery was the most likely course of action. By getting it out of the way as quickly as possible, there's a chance that he could recover in time for the start of the 2014 season, though shoulder injuries have been known to severely impact a pitcher's effectiveness.

Twins GM Terry Ryan said Thursday that Samuel Deduno is "leaning toward" undergoing shoulder surgery. A decision will be made at some point before the end of the 2013 regular season. Deduno has already been shut down with fraying in his right labrum and rotator cuff. He posted an 8-8 record, 3.83 ERA, 1.35 WHIP and 67/41 K/BB ratio in 108 innings (18 starts) this season.

Twins transferred RHP Samuel Deduno to the 60-day disabled list. This was merely done as a procedural move to clear a spot on the 40-man roster for the Twins September call-ups. Deduno is out for the remainder of the season, and could need shoulder surgery to repair the labrum and rotator cuff in his throwing arm.

Samuel Deduno could need surgery on his right shoulder. Deduno is having issues with his labrum and rotator cuff, though the good news is that Twins general manager Terry Ryan indicated Sunday it wouldn't be a major procedure. His season is obviously over, but it's not clear at this point how long Deduno's rehab would be.

Samuel Deduno underwent an MRI which revealed issues with his labrum and rotator cuff. Deduno left Thursday's start with right shoulder soreness and was placed on the disabled list Friday. We should know more about his status after he sees a specialist in Minnesota, but it doesn't sound good.

Twins placed RHP Samuel Deduno on the 15-day disabled list with a right shoulder soreness. The exact nature of the injury won't be known until Deduno undergoes an MRI Monday, but it's obviously bad enough to force a DL stint. Deduno dealt with a shoulder issue earlier this month before leaving Thursday's outing due to soreness.

Samuel Deduno will undergo an MRI on his right shoulder Monday. Deduno left Thursday's start after giving up three runs over three innings. We should know more about his status after the MRI, but it sounds like he'll miss at least one start. However, with rosters expanding on Sunday, the Twins should be able to get by.

Samuel Deduno left his start Thursday against the Royals because of right shoulder soreness. Deduno gave up three earned runs in three innings before being lifted. The Twins will run a range of tests on his shoulder to determine whether it's a serious injury.
