The Cincinnati Reds reinstated left-handed starter Nick Lodolo from the 15-day injured list Monday.
Lodolo will start against the St. Louis Cardinals on Monday afternoon. He last pitched May 11.
In a corresponding move, the Reds optioned right-hander Carson Spiers to Triple-A Louisville.
The Reds placed Lodolo on the 15-day injured list earlier this month with a left groin strain.
Lodolo, 26, is 3-2 with a 3.34 ERA in six starts this season. The 2019 first-round draft pick owns a 9-10 record with a 4.12 ERA in 32 career starts with the Reds.
Spiers, 26, appeared in four games in relief, going 0-0 with a 3.29 ERA.
