Sampson Boxing has announced the signing of Argentinean middleweight Walter Ezequiel Matthysse Jr. to a multi-year co-promotional contract, along with Argentina-based Tello Box.  His father, Walter Matthysse Sr., challenged Kermit Cintron for the IBF welterweight championship. The 21 year-old Matthysse is also the nephew of hard-punching former 140-pound title holder Lucas Matthysse.  A decorated amateur in his native Argentina, Matthysse started boxing at age 11 and has an outstanding amateur record of 59-3-1 (30 KOs). 

 

Matthysse will turn professional in Argentina at the conclusion of the pandemic with the goal of becoming the latest new star on the live-boxing television series Premier Boxing Champions in the United States.  “I’m very happy and proud that a company like Sampson Boxing has noticed me and I promise to give my best in this new stage of my career," said the young Matthysse.

 

Matthysse is trained by his uncle, Mario “Mauko” Narvaez, the brother of two-time world champion Omar Andres Narvaez and husband of two-time female world champion Edith Soledad Matthysse.  “We chose Sampson Boxing and Tello Box because I have known them for a long time and they give tranquility and security in the way they work,” said Narvaez. 

 

New co-promoter Lewkowicz says his newest fighter will be relocating his base of operations after making his high-profile debut at home.  “As soon as the pandemic allows it, Walter Jr. will make his professional debut live on TyC Sports in Argentina,” said Lewkowicz. “He will then be moving to Coachella, California, to train with Freddy Fundora after that, together with our great Uruguayan prospect Amilcar Vidal and one of the world’s best [154 pounders], Sebastian ‘Towering Inferno’ Fundora.”

 

“I am happy that Walter has signed with Sampson and Tello,” sad former middleweight world champion Sergio “Maravilla” Martinez. “Walter can trust his new team because he is surrounded by the best. It was a blessing that god put my career in the hands of Sampson.”

 

“This young fighter is from Argentinean boxing royalty,” continued Lewkowicz. “His father was a boxer. His uncle was a boxer. His grandfather was a boxer. His aunt was a boxer. I am very happy to be working with this future world champion and his family and team. Argentina will soon have another of its sons to fight on PBC and ShoBox and wear the world championship belt.”
