Frye captured his first Ultimate Fighting Championship on Feb. 16, 1996 defeating Ramirez and two other opponents. On May 17, 1996, Frye defeated Brazilian Jiu-Jitsu Champion Amaury Bitetti in a wild brawl. After losing his tile to Mark Coleman, Frye went undefeated for the next 8 years, beating among others Ken Shamrock and Tank Abbott.
