The right-hander has been on the disabled list since April 15 because of a strained muscle in his upper right arm. Barring a setback, he'll likely start one of the Reds' games early next week against the New York Mets, manager Dusty Baker said Wednesday.

Cueto pitched five shutout innings Tuesday for Class-A Dayton against West Michigan and earned the victory. He threw 58 pitches, walked none and allowed three hits.
