NEW YORK – One of boxing’s best prospects entertained the fans who arrived early Saturday night at Madison Square Garden.

Light heavyweight Joshua Buatsi battered Marco Antonio Periban for three-plus rounds before referee Tony Chiarantano stepped in to halt their scheduled 10-rounder on the Anthony Joshua-Andy Ruiz Jr. undercard. Chiarantano stopped the action at 1:39 of the fourth round.

The Ghanaian-born Buatsi, who won a bronze medal for England at the 2016 Summer Olympics, improved to 11-0 and recorded his ninth knockout. Mexico City’s Periban (25-5-1, 16 KOs) lost by knockout for just the second time in his 10-year pro career.

“Harsh to say, but maybe just under a five,” Buatsi, who’s managed by Joshua, said when asked to assess his performance. “I thought I rushed my work. I was too eager. I wanted to take my time and demonstrate my skill. But like I said, man, if I sense any vulnerability, we’ll capitalize. Most importantly, I’d like to thank God. I feel I got a good win in my U.S. debut. The fans welcomed me and I appreciate that.”

Buatsi’s right hand to the side of Periban’s head sent Periban to one knee with 2:14 to go in the fourth round. Periban complained to Chiarantano that Buatsi hit him on the back of his head before he went down.

Once Periban got to his feet, Buatsi continued his assault on his retreating opponent until Chiarantano had seen enough. A right hand by Buatsi knocked Periban into the ropes and off balance just before Chiarantano stopped the fight.

“He was slippery in the early rounds,” Buatsi said, “but once I hurt him, I said, ‘Man, it’s time. It’s time.’ It was time, man. Tonight was my night.”

An overhand right by Buatsi rocked Periban with about two minutes to go in the third round. Buatsi caught Periban with several left hooks during a largely one-sided second round.
