The Twins are placing reliever Anthony Swarzak on the 15-day disabled list with a mild rotator cuff strain, and promoting righthander Luis Perdomo from Class AAA Rochester to take his 25-man roster spot.
Perdomo had to be added to the 40-man roster, so to make room, the Twins moved Carl Pavano to the 60-day DL.
Perdomo, 28, was 2-1 with a 0.92 ERA and seven saves in 11 appearances for Rochester, with 18 strikeouts and two walks in 19 2/3 innings.
Pavano, who is out with weakness in his right rotator cuff, is headed to Fort Myers, Fla., for the next phase of his rehab.
