Johnny Cueto strained a lat muscle on April 13, leading to nearly five weeks on the disabled list.
He has made three starts for the Reds since, allowing eight hits over 20 innings for a 1.80 ERA. Cueto is 3-0 with a 2.17 ERA in six starts overall this season.
"I feel really well," Cueto said. "I made the adjustment I had to make and I feel good so far. It's good to come back because here was the place I got hurt."
