Mason (17-0, 15 KOs), who turns 21 on fight day, enters his first scheduled 10-rounder riding a wave of momentum. He knocked out Manuel Jaimes in four rounds in February on the Denys Berinchyk-Keyshawn Davis bill in New York City. Mason went 5-0 with five early stoppages in 2024 and ascended from a promising prospect to a wunderkind contender.
Ornelas (28-4, 15 KOs) is the most battle-tested foe of Mason’s pro career, a 30-year-old with extensive experience against established Mexican opposition. He has won three fights since losing a 10-round decision to Rafael Espinoza in January 2021. Ornelas is coming off a December 2023 decision win over David Moreno Potrero, who entered that bout with a 16-0-1 record.
