Former Aces' catcher John Hester will be returning to Reno after getting optioned by the Arizona Diamondbacks on Saturday.
Hester, Ryan Roberts, Rodrigo Lopez and Zach Kroenke were all optioned by Arizona.
Rusty Ryal, an All-Star with Reno last season, was the final addition made to the big club's 25-man roster in Arizona.
Hester was named to the All-Pacific Coast League team last season after hitting .328 with nine home runs and a career-high 68 RBI with the Aces.
He hit a home run in his first Major League at-bat after being called up by the Diamondbacks, last August.
