The Diamondbacks optioned Carrillo to Triple-A Reno on Monday.
Carrillo will give up his spot on the 26-man active roster and in the Arizona bullpen to right-hander Justin Martinez (elbow), who was reinstated from the 60-day injured list. After being recalled from Triple-A on July 21, Carrillo made eight relief appearances for the Diamondbacks, picking up two wins while delivering an 0.66 ERA, 1.10 WHIP and 15:8 K:BB across 13.2 innings.
