Rodriguez (elbow) will begin a rehab assignment with Triple-A Sacramento on Sunday, Justice delos Santos of The San Jose Mercury News reports.
Rodriguez has been out for all of August with right elbow neuritis, but he's been cleared to test things out in games. The 24-year-old shouldn't require too many rehab contests, and once he's reinstated the Giants are expected to use the utility player more in the infield than at catcher or in the outfield.
