Sanchez (calf) was sent to Triple-A Nashville on Friday to begin a rehab assignment, Todd Rosiak of the Milwaukee Journal Sentinel reports.
Brewers manager Pat Murphy indicated last week that Sanchez was well ahead of schedule in his recovery, and he appears to be in the home stretch. Sanchez's rehab assignment comes three and a half weeks after he suffered a strained left calf, and while he'll likely be eased into catching duties, he could be activated in late July or early August.
