Frye rose to fame fighting in early Ultimate Fighting Championship events, winning the UFC 8 and Ultimate Ultimate 96 tournaments. He holds notable victories over Ken Shamrock, Gary Goodridge (2x), Tank Abbott, and Gilbert Yvel.

In 1987, he won the freestyle and Greco-Roman events during an Olympic qualifier. A year later, he transferred to Oklahoma State, where he encountered another future UFC star amongst his teammates: Randy Couture.

On August 28, 1989, Frye made his professional boxing debut against Luis Mora in Phoenix, Arizona and won via first round knock out. This was to be his final pro boxing bout.

In 1995, Frye helped train his old friend Dan Severn for the Ultimate Ultimate 1995, accompanying Severn's entourage to Denver. Severn returned the favour in 1996, when he acted as Frye's manager for UFC 8. Fighting three times in one night, Frye dispatched all of his opponents in just under a minute total, winning the tournament with relative ease. At this event Frye set the record, since broken by Duane Ludwig, for fastest KO in the UFC at just 8 seconds.
