Anthony Swarzak will replace injured Twins righthander Nick Blackburn in the starting rotation, Manager Ron Gardenhire said after Sunday's 3-0 loss to the Yankees.
Blackburn was diagnosed with a right lateral forearm strain and will be re-evaluated Monday. With his right hand facing down, Blackburn pointed to the top of his right forearm, describing where he felt what he called a "sharp" pain.
"It’s a big chunk of muscle," he said. "It’s not anything that’s in the tendons or anything like that, so I think that’s pretty good."
Swarzak pitched three innings of relief Friday and retired all eight batters he faced Sunday after relieving Blackburn. Swarzak is 3-3 with a 3.12 ERA in 20 games this year, including 2-2 with a 3.16 ERA in five starts.
Gardenhire said there will be a roster move Monday, so Blackburn is likely headed to the DL, with a reliever coming up from Class AAA Rochester.
