Keyshawn Davis prevailed in a battle of unbeatens and won his first world championship Friday. Davis, the 25-year-old American, defeated Ukrainian Denys Berinchyk by knockout and claimed the WBO world lightweight title.

Davis ended the fight with a pair of body shots that convinced Berinchyk, bloodied from his nose and swollen around his face, to take the full count on his knee. With the victory, Davis became a world titleholder just shy of his fourth anniversary of turning professional.

Keyshawn Davis knocked out Denys Berinchyk in the fourth round to win his first world title by picking up the latter’s WBO Lightweight Belt. The win was all the more impressive given the pre-fight antics.
