A professional mixed martial arts bout can be scheduled for 15 minutes and require months of preparation. Jorge Masvidal needed an official five seconds to finish Ben Askren—and even that timing makes the action sound longer than it looked.
The welterweights met at UFC 239 on July 6, 2019, in Las Vegas. When the fight began, Masvidal exploded into a sprint. Askren, an elite wrestler, lowered his level as if preparing to grab the legs. Masvidal jumped and met him with a flying knee.
The official UFC Record Book lists the finish at 0:05, making it both the fastest finish and fastest knockout in UFC history. ESPN’s event report independently records the same time and result.
The move was planned, not improvised
The spectacular collision can look like a reckless gamble, but Masvidal and his team had studied Askren’s habits. Askren was famous for pressuring opponents into wrestling exchanges, so the opening charge was designed to meet a likely takedown attempt.
An ESPN breakdown of the finish reports that Masvidal and coach Mike Brown had prepared the sequence well before fight night. The timing still required extraordinary commitment: once Masvidal started running, there was almost no room to adjust.
One second faster than the old record
Before UFC 239, the promotion’s fastest knockout belonged to Duane Ludwig, whose 2006 victory over Jonathan Goulet was officially recorded at six seconds. Masvidal removed a single second from the mark. On a normal clock, that difference feels trivial; in a record this short, it represents one-sixth of the previous total.
The UFC’s ranking of 2019’s best knockouts placed Masvidal’s finish first and described how Askren’s level change took him directly into the strike.
Why five seconds can include an entire story
There was a tense rivalry before the bout, a tactical prediction during camp, an explosive opening and an immediate stoppage. Askren entered unbeaten in professional MMA; the result became his first official loss.
Masvidal’s official UFC record still lists the Askren win at five seconds. Years later, the moment remains a perfect example of how preparation can compress an entire fight into one decisive movement.
