Pace then joined the Bellator Fighting Championships and gained notice in the media with a flying knee KO of Collin Tebo.

[7] Pace defeated Campuzano in the 3rd round with a pillory choke, which was the first time the submission was used in a professional mixed martial arts bout.
After four years away from competition, Pace made his return to MMA and fought for the CFFC Bantamweight Championship against Ricky Bandejas on Oct 31, 2015.
A year later, Pace made his comeback to martial arts competition in the Combat Jiu Jitsu Worlds BJJ tournament.
