Reinier de Ridder is a lanky Dutch submission ace who once held ONE Championship belts in two divisions at the same time. Thirteen of his 21 wins come by submission, built on suffocating clinch work, trips, and relentless top control. His UFC middleweight run peaked with a win over Robert Whittaker before back-to-back losses to Brendan Allen and Caio Borralho stalled the climb. He now moves up to light heavyweight, where he was a champion in ONE, hoping the bigger frame fits him better.
