The Read
Style, strengths, and where this fighter stands.
Harris is a 6-foot-6 orthodox heavyweight with a boxing base — the nickname 'The Hammer' points to a heavy right hand — and until the UFC his finishing had actually leaned on the mat, with three of his six wins by submission (a guillotine, an Americana and a forearm choke). He is a fast starter who has now closed five of six fights inside the distance, usually in the first or second round.
The record before the call-up was short and entirely regional: a perfect 5-0 across Ohio Combat League, Caged Thunder and, most recently, two wins on the LFA feeder circuit. That step-up and a run of quick finishes earned him a short-notice UFC call to replace Allen Frye Jr. opposite Alvin Hines, and the debut answered the question of whether the front-loaded finishing travels: he was patient, drew Hines onto an uppercut, and finished on the ground at 1:40 of the first to move to 6-0 — this time with the right hand rather than the choke.
