Whoever takes Sebastian “The Towering Inferno” Fundora's unbeaten record will be a giant killer.

BoxNation viewers will see fellow undefeated fighter Hector Manuel Zepeda attempt that when he stands up to the freakishly tall 6ft 7in prospect in Iowa on Friday (June 21), live on BoxNation.

The fact he can make 11 stone is crazy and nobody will argue with his claim to be the tallest super-welterweight in history.

Southpaw Fundora has even revealed he has grown since his third round knockout of Donnie Marshall in February.

“I think I grew another inch,” laughed the California man ahead of the non-title ten rounder. “I get measured at every training camp and it looks like I might have gotten taller by an inch.”

Fundora, 21, said: “I’m not only getting taller, I’m also getting stronger.

“I’m maturing, so age is kicking in. My jab will always be my best punch, but my power is increasing fight after fight.

“I was sparring with a lot of bigger guys and not getting pushed around by anyone. I’m already on weight too.

“My dad says he doesn’t want me to have to go through a fat camp and a training camp every fight so I stay in shape at all times.”

Fundora, who had more than 100 amateur fights, was born in Florida but now lives on the America west coast in Coachella.

His father Freddy trains the youngster who has won all 12 fights and puts a lot of trust in strength and conditioning coach JR Corrales.

Trainer Freddy says: “With every camp, he matures. He’s growing and that’s very important in the sport.

"From here on out, we’re just going to be sharpening the tools he already has which are his strength, power and boxing IQ.

"Zepeda looks like he’s going to try to box, but both of these kids are from boxing families and that always makes for fireworks. You’re going to see two guys who have come to fight and put on a show Friday.”

His promoter Sampson Lewkowicz insists he has another future world champion adding: “Boxing is in his blood.

“Everyone in his family was a fighter. He’s going to be a world champion. I believe in him. He has worked very hard to become an overnight sensation in boxing.”

“Fundora is a big guy for the division,” said the 21-year-old Zepeda. “He’s talented, but I prepared very hard for this fight. I’m ready to give it all on Friday night. This is my first fight in the United States and I have been waiting my whole life for this.”

“Fundora is very different to the guys that I’ve fought before. He’s a tall lefty, so I had to make a lot of changes to how I normally do things.

“I have been sparring with lefties and tall guys like Antonio DeMarco and Julio Cesar Chavez Jr. I’ve been working hard. I’m ready for him. I’m confident I’ll get the win.”
