Padres reliever Dale Thayer began his minor league rehab assignment on Saturday. Thayer made the start for Double-A San Antonio, allowing three runs on three hits in one inning of work.
The right-hander has been on the disabled list since June 24--and hasn't pitched since June 16--due to a strained shoulder. It is not known when Thayer will be ready to return to the Padres' bullpen.
