A Brooklyn man who was a behind-the-scenes worker at big Barclays Centers shows will be the show this weekend, when he takes center stage at the arena for a boxing match. NY1's Jeanine Ramirez filed the following report.

Travis Peterkin says he was always good with his hands.

"I was boxing since I was 11 years old. I was one of those kids who used to get into a couple of fights outside. Growing up in Brownsville, if you didn't know how to fight, you know, you're going to have a tough time," said Peterkin.

Now, he's a 24-year-old professional boxer training at Gleason's Gym for the biggest fight of his career, a bout Saturday night at Barclays Center. He knows the arena well because he used to work here.

"I used to tell some of my friends, 'Yo, one day, I will fight here,'" Peterkin said. "And I mean, they never discouraged me. They were like, 'Well, we're going to see, Travis.' I'm like, 'Listen, I'm telling you, I'll be here one day and I'm going to do what I got to do.'"

What he used to do was stock the refrigerator, set the spread and serve the guests as a Barclays Center suite runner.  Peterkin worked there when the arena opened in 2012 until last year.

"I applied, like everybody else, for an application to work there," he said. "It was a very humbling experience being a suite runner."

It also helped pay the bills, with a baby girl on the way.

However, boxing was his passion, and the light heavyweight went on to win the Golden Gloves. He's now undefeated, 15-0, with seven knockouts.

Peterkin's father, Bernard, a longtime trainer, is helping him.

"When he said that he wanted to learn how to box, I told him that I'm going to do it, but I'm going to be hard on him. Because it's really not easy, and I didn't want him to have any shortcuts or anything like that," Bernard Peterkin said.

The main event Saturday is Danny Garcia versus Brooklynite Paulie Malignaggi. Travis Peterkin is in the featured bout on the undercard. His challenger, Lenin Castillo, is also undefeated and is a former member of the Dominican Olympic team.    

"I'm good at what I do, but there's always somebody out there training just as hard as you who want to be the man," Travis Peterkin said. "So come Saturday night, I'm going to have to take him out."

The doors at Barclays Center open at 5:30 p.m. Peterkin is expected to fight around 7:30 p.m.
