Latos will make his 2014 debut after right elbow and left knee surgeries kept him out to open the season. Latos was 2-0 with a 2.33 ERA in four minor league rehab starts. He went 14-7 with a 3.16 ERA last year for Cincinnati.
Sean Marshall was placed on the 15-day DL, retroactive to June 10, to make room for Latos.
Reds manager Bryan Price said before Saturday's game that, ''(Marshall) just can't pitch with (the shoulder injury.) He is not himself. We would like to avoid (surgery).''
