Irish fighter Callum Walsh headlined Zuffa Boxing's inaugural event in Las Vegas, securing a unanimous decision victory over Mexico's Carlos Ocampo. The 24-year-old improved his professional record to 16-0, overcoming a sixth-round knockdown that appeared more a loss of balance than a clean hit. Judges scored the 10-round bout 98-90, 98-90, and 97-91 in his favor.

The event marks UFC boss Dana White's first foray into professional boxing promotion through a joint venture between TKO Group Holdings and Saudi Arabia's Sela Sport. A star-studded crowd, including executives from UFC and WWE, attended the Meta Apex venue. Jai Opetaia, the cruiserweight world champion, is currently the biggest name signed with the new promotional company.

Walsh expressed post-fight disappointment at not securing a knockout, a common sentiment among fighters seeking to make a statement. However, he acknowledged the importance of completing another 10-round bout against increasingly tough opposition. The win establishes Walsh as a potential headliner for Zuffa Boxing's future events as it seeks to carve a niche in the crowded combat sports market.
