On Saturday night at Climate Pledge Arena in Seattle, Joe Pyfer delivered the most startling result of his UFC career, stopping the former two-time middleweight champion via ground-and-pound TKO at 4 minutes and 18 seconds of Round 2. Pyfer, 29, controlled Adesanya on the canvas, took his back, worked his way to mount, and landed the punches that prompted referee Herb Dean to wave off the contest. What was once a skeptic’s fight card became, in an instant, a career-defining moment for a fighter who entered the Octagon as a +124 underdog.
