Giants reliever Santiago Casilla returned Saturday from the 15-day disabled list after missing all but opening day with an inflamed right elbow.

Casilla was a key member of the Giants' bullpen last season, going 7-2 with a 1.95 ERA in 52 appearances. He pitched one inning this season, giving up a run in San Francisco's season-opening loss to the Los Angeles Dodgers.

To make room for Casilla, the Giants optioned left-hander Dan Runzler to Triple-A Fresno in an effort to get him more work and stretch him out to make him available for additional innings.

San Francisco played at Milwaukee on Saturday.
