Jorge Masvidal is one of the UFC's most feared strikers, and his five-second knockout remains the fastest ever recorded. Nicknamed Gamebred, the veteran welterweight built a career in mixed martial arts on relentless aggression, most famously sprinting across the cage at UFC 239 in July 2019 to land a devastating flying knee on Ben Askren, knocking him unconscious before a single takedown attempt landed. The finish shattered the previous UFC record of six seconds, held by Duane Ludwig since 2006, and remains a Guinness World Record. Masvidal later defended following up with ground strikes, calling them super necessary. Known for ferocious knockout power and street-fighting instincts, Masvidal remains one of combat sports' most explosive needle-movers in UFC history.
Seven years on, Jorge Masvidal's flying knee at UFC 239 still stands as the fastest knockout in UFC history — a five-second finish that rewrote the record books and cemented the Miami-born welterweight's status as one of combat sports' most electric performers.
Masvidal, nicknamed Gamebred, carried a 35-17 record into the twilight of his career and built his reputation on unrelenting aggression and raw knockout power. The 41-year-old American Top Team product stands five-foot-eleven with a 74-inch reach and lands significant strikes at a rate of 4.05 per minute — numbers that reflect a fighter always hunting the finish. His instincts in that July 2019 bout were on full display from the opening horn, when he sprinted across the Octagon and launched a flying knee that rendered his opponent unconscious before a single defensive scramble could develop.
On the receiving end was Ben Askren, a decorated wrestler whose 19-2 record was built almost entirely on suffocating grappling. The 42-year-old from the United States averaged 4.33 takedowns per 15 minutes throughout his career, and it was precisely that anticipated grappling attack that Masvidal turned against him, timing the charge to land before Askren could ever establish his game.
The finish clocked in at five seconds, shattering the previous UFC record of six seconds held by Duane Ludwig since 2006, and earned recognition as a Guinness World Record. In the aftermath, Masvidal defended the follow-up ground strikes as, in his words, super necessary.
Why it matters
- The record has stood for over seven years with no finish coming within striking distance of five seconds.
- It remains a defining moment in welterweight division history, blending tactical reading with pure explosiveness.
- The Guinness certification elevates it beyond sport, placing Masvidal's name in a category few athletes in any combat discipline can claim.
