He said he rehabs his elbow on the days he doesn't throw, including a towel drill where he does his normal throwing motion but with a towel in his hand instead of a baseball.
"I'm just building up," Pelfrey said. "Everything is good."
Pelfrey last pitched with the Twins on May 1 before being placed on the DL with a groin strain. He made two rehab starts with Triple-A Rochester, but felt discomfort in his elbow. He ultimately had surgery to clean up scar tissue in his right elbow that was causing pressure on his ulnar nerve on June 10.
Pelfrey, 30, is under contract next year after signing a two-year, $11 million deal before this season. He posted a 7.99 ERA in five starts before going on the DL.
"We'll start him fresh next year," Twins general manager Terry Ryan said. "He'll be ready for Spring Training. But I don't see any reason why we have to push that one."
