NEW YORK – Marcus Browne barely broke a sweat Saturday night.

The unbeaten light heavyweight contender needed just two minutes and 15 seconds to stop Francy Ntetu in a fight that was scheduled for 10 rounds on the Errol Spence Jr.-Lamont Peterson undercard at Barclays Center.

Staten Island’s Browne drilled Ntetu with a right hook and then a left hand that knocked down Ntetu, who fell forward as he tried to get up. He eventually reached his feet, but didn’t last much longer.

Referee Arthur Mercante Jr. stopped the action soon thereafter, as Browne was unloading power shots on Ntetu, who was still standing, trying to survive near a neutral corner.

“We worked for this win,” Browne said. “He walked into a sure shot and I made him pay. The overhand left caught him and that was the beginning of the end for him. I knew he was hurt.”

Browne improved to 21-0 and recorded his 16th knockout.

“I need a world title shot,” Browne said. “I’m ready to take on any of the champions. I don’t have any preferences.”

Montreal’s Ntetu (17-2, 4 KOs) lost by knockout for the second time in three fights. Since-crowned WBC super middleweight champ David Benavidez beat Ntetu by seventh-round technical knockout in that June 2016 bout at Barclays Center.

“[Browne] is very explosive,” Ntetu said. “Congrats to him. He’s explosive, he’s fast, he’s smart.”

Also on the card, Anthony Peterson pounded out a 10-round, unanimous-decision win against Luis Florez on his older brother’s undercard Saturday night at Barclays Center.

Peterson repeatedly went to Florez’s body and remained in control throughout the mostly uneventful fight. He made Florez retreat after landing several hard body shots late in the ninth round, but the durable Florez was able to finish all 10 rounds on the non-televised portion of the Errol Spence Jr.-Lamont Peterson undercard.

Peterson (38-1, 24 KOs) defeated Florez (23-9, 19 KOs) easily by winning each of the 10 rounds on all three scorecards (100-89, 100-90, 100-90).

The 32-year-old Peterson ended nearly a three-year layoff by fighting Florez. Before Saturday night, he hadn’t boxed since winning a 10-round unanimous decision against Samuel Neequaye in March 2016.

In the opener of the nine-bout card, welterweights Keyshawn Williams and Denis Okoth fought to a four-round draw.

Williams (1-0-1, 1 KOs), of Washington, D.C., won 39-37 on one scorecard, as did Kenya’s Okoth (1-0-1, 1 KO). The third judge had it even (38-38).
