The Twins made some roster moved last night and they include placing outfielder Delmon Young on the 15-day disabled list with a strained oblique.  The move is retroactive to April 19.  Young is replaced on the active roster by outfielder Rene Tosoni.  Tosoni was hitting .286 with 3 homeruns and 16 RBIs at triple-A Rochester.  The Twins also called up righthander Anthony Swarzak to start the 2nd game of the day/night doubleheader today.  He was 1-1 with a 4.87 ERA in 4 starts at triple-A Rochester.  The Twins sent down reliever Eric Hacker to make room for Swarzak.  Hacker threw 3 1/3 innings of relief with 1 unearned run allowed Wednesday night.  Kevin Slowey is close to returning.  He threw 1 innings with 1 run allowed at extended spring training in Fort Myers, Florida.  Slowey could return as early as this weekend.  Catcher Joe Mauer (leg weakness) will stay on the disabled list today despite being eligible to return.  Manager Ron Gardenhire says there is no timetable for his return.
