Twins righthander Samuel Deduno continues to deal with inflammation in his shoulder and could be headed for surgery.
Twins General Manager Terry Ryan said Sunday that a decision will be made in about 10 days whether to have surgery or opt for rehabilitation.
‘‘We’re making a decision on the severity of this thing and whether or not there’s a possibility of a scope,’’ Ryan said.
Deduno recently has seen a specialist and has had a magnetic resonance imaging exam on his shoulder. Indications are that he’s still battling some inflammation and that there is some fraying in the area. Ryan, however, maintained that the problem is scar tissue-related.
‘‘It is more favorable than we thought,’’ Ryan said.
Deduno went 8-8 with a 3.83 ERA in 18 starts this season but reported soreness in his shoulder after an Aug. 18 start. He remained in the rotation and pitched well in an Aug. 23 start at Cleveland but had no life on his pitches in his next start against Kansas City and was pulled from the game after three innings. He hasn’t pitched since and is done for the season. He went 1-4, 5.96 over his past five starts.
Surgery or no surgery, Deduno will return to his native Dominican Republic. He could wind up pitching winter ball, which will be a decision left up to him.
‘‘I would say that he doesn’t need to throw,’’ Ryan said. ‘‘That would be an opinion that I have not voiced to him because he has not asked. But I don’t see it. He’s had plenty of work.’’
Here comes the cavalry
Class AAA Rochester was eliminated from the International League playoffs Sunday, and the Twins quickly announced who was being called up for the final 21 games of the season.
Infielder Eduardo Escobar, catcher Eric Fryer, first baseman-outfielder Chris Parmelee, lefthander Scott Diamond and righthanders Michael Tonkin, Cole De Vries and Shairon Martis are headed to the Twin Cities and should be in uniform in time for Monday’s game against the Angels.
With Diamond and De Vries both starters, the Twins have discussed using a six-man rotation. But Twins manager Ron Gardenhire said nothing has been decided yet.
Ryan said he expected catcher Joe Mauer’s return from a concussion to be a matter of days and not weeks.
Mauer ran the bases and hit in the batting cages on Saturday. The Twins did not work out on the field before Sunday’s game — which is typical on day games following night games — so Mauer worked out indoors.
He has yet to be cleared by Major League Baseball to return to action, but the fact he’s running could be a positive sign.
Mauer has been out since Aug. 19 after taking a foul ball off his facemask during a game against the Mets. He experienced symptoms the next day and has been on the league’s concussion DL ever since. He’s been able to add hitting and running to his workouts in recent days.
