Keyshawn Davis delivered the type of dominant performance he promised Friday night.

The emerging star destroyed Denys Berinchyk on his way to a fourth-round knockout that won him the WBO lightweight title in a main event ESPN televised from The Theater at Madison Square Garden. Davis dropped Berinchyk once apiece with left hooks to the body in the third and fourth rounds.

Referee Harvey Dock counted out a battered, bloodied Berinchyk (19-1, 9 KOs) at 1:45 of the fourth round in this battle of Olympic silver medalists.

Davis, 25, became a lightweight world champion in just his 14th professional appearance, 3½ years after the Norfolk, Virginia native won a silver medal at the 2021 Summer Olympics in Tokyo. Davis’ dominant victory also punctuated a tense promotion, during which Davis (14-0, 9 KOs, 1 NC) accused Berinchyk of being a “racist” on Wednesday because a box of bananas and watermelons were delivered to his hotel room Tuesday.

Ukraine’s Berinchyk, 36, lost the WBO 135-pound championship he won by beating Emanuel Navarrete by split decision in his last fight, a 12-rounder May 18 at Pechanga Arena in San Diego. The Kyiv native entered their fight as The Ring’s No. 6 lightweight contender, one spot below the fifth-rated Davis.

Berinchyk bled from his nose early in the fourth round and an aggressive Davis pushed to finish his reluctant opponent.

Davis drilled Berinchyk with a left hook to the body that sent him to the canvas less than 30 seconds into the third round. Even though Berinchyk beat Dock’s count relatively easily, that knockdown signaled the beginning of the end for the former champion, who couldn’t handle Davis’ speed, power, movement or IQ.

Davis tried to land right uppercuts during the second round, but Berinchyk tied him up several times. Berinchyk wasn’t aggressive, either, which led to a second straight uneventful round.

Berinchyk moved away from Davis throughout the first round, which drew boos from a disapproving crowd. Davis predicted a first-round knockout, but Berinchyk barely engaged with Davis during the first three minutes of their fight.
