The Twins will reinstate closer Matt Capps from the 15-day disabled list prior to Friday night's game against the Athletics.
Capps was placed on the disabled list on June 25 (retroactive to June 24) with right shoulder inflammation. He pitched two innings in two rehab appearances at Class-A Ft. Myers.
To clear a spot on the active roster, the Twins optioned right-handed pitcher Kyle Waldrop to Triple-A Rochester.
Waldrop, recalled June 29, went 0-1 with three walks and one strikeout in four appearances with the Twins.
