Lucas Bahdi scores one of the most vicious KOs you will ever see when he turns the lights out on Ashton Sylve

Chances are good that unless you are a super hard core boxing fan, you may never have heard of Lucas Bahdi prior to Saturday's bout against Ashton "H2O" Sylve on Saturday at Amalie Arena in Tampa, Fla. And, perhaps true to form, Bahdi put in a pretty unforgettable five rounds and was doing absolutely nothing to indicate he had a prayer of beating Sylve.

But one of the charms of boxing is that momentum can change in an instant and a career trajectory can be altered with one punch.

Bahdi made a loud statement in the sixth, catching Sylve with back-to-back right hands and then a left hook.

Sylve did a face plant to the floor and the fight was instantly over at 2:27.

Prior to that combination, Sylve was dominating the fight, using his speed, quickness and boxing ability to rack up the rounds. Power is the big equalizer and Sylve found that out.

"He's very twitchy, very quick," Bahdi said when asked why he was having trouble with Sylve. "I was trying to get to him in the body early on and I was a little hesitant for some reason. My legs weren't really under me as they usually are, so it was tough to get in quick on him. He's very fast and he has good counter punches. It was tough to touch him at the beginning."

According to CompuBox, it was hard for Bahdi to touch him all night. Including the knockout punches, Bahdi landed just 39 punches in the entire bout.

He didn't need 40, though, to get the job done.

Bahdi is now 17-0 with 15 KOs. Sylve, 20, is 11-1. Sylve left the ring under his own power, though he was very unsteady.
