Wilson lands on DL with balky elbow
The move announced Sunday is retroactive to Tuesday. San Francisco also recalled right-hander Steve Edlefsen from Triple-A Fresno.
Wilson hasn't pitched since he blew a save on Monday at Atlanta. He began the season on the DL with a left oblique strain.
Giants manager Bruce Bochy says he is hopeful that Wilson will return to the team at the end of time on the 15-day disabled list.
