Hoping to become the next Dominican world champion in boxing, undefeated Luis “The Twist” Nunez continues to up his competition as he takes on Argentina's Hector Sosa in a ten-round junior lightweight duel. Nunez-Sosa takes place on Saturday, October 25th at the MGM Grand Garden Arena in Las Vegas. It will be shown on PBC on Prime Video lineup  and leading up to the PBC Pay-Per-View event on Prime Video prior to a PBC pay-per-view headlined by WBC 154-pound champion Sebastian “The Towering Inferno” Fundora defending against former unified welterweight champion Keith “One Time” Thurman.

 

Nunez (21-0, 14 KOs) can take another step closer to a 130-pound title shot with a victory on October 25th. Originally from Puerto Plata, Dominican Republic and now being guided by trainer Bob Santos in Las Vegas, Nunez kicked off his 2025 campaign in June by dispatching of Daniel Ramirez in the fourth round. The 25 year-old had previously shown his bona fides with a run that saw him best four previously undefeated fighters in a stretch of five outings. He followed up that run in December 2024 by earning a dominant ten-round unanimous decision over gatekeeper Leonardo Baez ahead of the Ramirez fight. 

 

“I’m excited to be fighting a tough Argentinian at the MGM on a Sebastian Fundora undercard,” said Nunez. “It’s a blessing that this fight will be on Prime Video, because I’ve been working so hard with my trainer Bob Santos and I know that I’ll be ending the night in spectacular fashion. I’m going for fight of the night, so make sure you tune in early!”

 

The 29 year-old Sosa (18-3, 9 KOs) is no stranger to springing upsets on unsuspecting foes as he showed his power carry into the later rounds when he knocked out top U.K. fighter James Dickens in July 2023. Overall, Sosa has won four of his last five bouts, including most recently earning a unanimous decision over Liborio Solis in May. The Buenos Aires native has previously fought stateside three times, including a twelve-round decision over Keenan Carbajal in June 2024.

 

“I love to be the underdog because it makes it even sweeter when they announce me as the winner,” said Sosa. “I’ve been training hard and I’ll be ready to give Nunez everything he can handle. Don’t miss this fight, because I’m coming to show what Argentinian fighters are made of!”
