Rodriguez was called up from Triple-A Gwinnett on Saturday.
Rodriguez will join Atlanta at home after the team claimed him off waivers from Minnesota on May 15. The right-hander has appeared in one major-league contest in 2023, allowing one run on one hit and a walk over two-thirds of an inning against the Cubs on May 12. Rodriguez will slot in as an additional bullpen option for Atlanta, though he carries limited fantasy appeal.
