Japanese boxer Jin Sasaki just delivered one of the coldest knockouts you’ll see all year

Thursday night out of Korakuen Hall in Tokyo, 24-year-old Jin Sasaki did something that is going to be living rent free in the combat sports conversation for a while.

Here’s what makes this one so ridiculous. Jin Sasaki’s opponent, Marlon Pagalpalan, landed somewhere in the neighborhood of 40 unanswered punches on the guy.

Forty.

Jin Sasaki was eating shots, absorbing punishment, looking like a man who had no business being in that ring at that moment and then, out of nowhere, he found his window and threw one left counter that sent Pagalpalan crashing to the canvas and completely unable to get back up.

One punch after eating forty. That’s the whole story.

The walkoff knockout is already one of the most satisfying things in sports when it lands, but what separates this one is the setup. Jin Sasaki wasn’t dominating the fight when it happened. He was surviving it.

The patience required to stay composed while getting tagged repeatedly and still trust that your moment is coming is a different kind of mental toughness, and when that moment finally arrived he did not waste it.

Jin Sasaki was coming off a knockout loss to former WBO welterweight champion Brian Norman, so there was real pressure on him to come back and look clean in his return. Instead he came back and looked legendary. That left hand is going to be on highlight reels for a long time.

Combat sports weekends that start like this are always a good sign for what’s to come.

What a way to kick it off.
