Gervonta Davis proved he is one of the scariest punchers in boxing

• Gervonta Davis scored a frightening knockout Saturday over Rolando Romero in New York City.
• The 27-year-old American separated Romero from his senses in the sixth round.

Gervonta Davis finished lightweight rival Rolando Romero in the sixth round of a boxing match Saturday at the Barclays Center in New York City.

The manner in which Davis did so was frightening as he didn't simply knock Romero out — he seemingly knocked him into another dimension.

All it took was one punch. One counter left hand that was timed so beautifully, it did not even need to be thrown full force.

"The crazy thing is that I didn't even throw it that hard," Davis said. "He just ran into it."

It connected with Romero's chin, separated him from his senses, and dropped him in such dramatic fashion that he bounced off the ropes and onto the floor.

Someway, somehow, Romero managed to get back up to his feet. The referee performed basic checks to ensure he had regained his wits but it was clear he hadn't.

Romero had simply been reanimated. His legs remained wobbly and his eyes were all over the place. The wheel was spinning but the hamster was dead.

Romero was done. It was over.

The knockout punch had such a profound effect on him that when officials escorted him out of the ring before the result had been announced, it still seemed like he didn't even know where he was or what had just happened.

For everyone else, it was clear what had happened. Davis, one of boxing's scariest punchers, had done it again.

Watch the finish right here:

The 27-year-old is one of the hottest attractions in all of the combat sports.

He's a proven ticket seller regardless of whether he's competing in Baltimore, Atlanta, or Los Angeles. The Mayweather Promotions fighter attracts big crowds, just like he did in Brooklyn — with celebrities like Madonna and Tracy Morgan watching the show from ringside.

Davis is also a staple on Showtime's pay-per-view division, with Showtime Sports boss Stephen Espinoza telling Insider earlier this month that the company is delighted with the increasing interest in the heavy-hitter.

As for what's next, Romero — who had sufficiently recovered to attend the post-event press conference — told reporters that he had won every round and got caught. He began his campaign for a rematch.

"Shout out to him," Davis told reporters with a smile, laughing off the call-out.

Romero could rebuild to get himself back into a position to fight someone like Davis.

But, right now, greater challenges await Davis.

He could box Gen-Z superstar Ryan Garcia, who was also ringside at the time. Or he could challenge the winner of the June 4 unification fight between George Kambosos Jr. and Devin Haney.

Whether sporting politics get in the way of those bouts materializing remains unclear.

But what is clear is this: After finishing the likes of Leo Santa Cruz, Mario Barrios, and now Romero, in the manner in which he did so, Davis is one of the scariest punchers in his sport.
