MINNEAPOLIS -- After staying home with flu-like symptoms on Saturday, right-hander Anthony Swarzak rejoined the Twins at Target Field on Sunday.
Swarzak battled those symptoms during his spot start against the Tigers on Friday, when he allowed six runs on nine hits over 3 2/3 innings.
He was moved back to the bullpen after that outing, and is expected to be ready to pitch in long relief by Monday or Tuesday.
"We'll have Swarzy back here in a day or so," manager Ron Gardenhire said. "We'll have some flexibility."
Swarzak has fared well as a reliever, posting a 3.06 ERA in 17 2/3 innings, but he has struggled as a starter, with an 8.34 ERA in 18 1/3 innings.
