An array of talented fighters from the Los-Angeles area round out the evening as Oxnard’s Hugo “The Boss” Centeno Jr. (24-1, 12 KOs) competes in a middleweight attraction, former title challenger Josesito Lopez (33-7, 19 KOs) of Riverside in a six-round welterweight fight and Abner Mares’ younger brother, Adan Mares (14-1-3, 3 KOs) enters the ring in a lightweight bout.

An accomplished amateur who was born in Kazakhstan but fights out of Russia, Lipinets turned pro in April of 2014 with a decision victory over Franklin Varela. The 27-year-old recorded six knockouts in a row before stepping up in competition and impressing with a victory over Haskell Lydell Rhodes in March 2015 and a knockout of Levan Ghvamichava in March. He kept the momentum going in July when he stopped established contender Walter Castillo in the seventh round. He will challenge the 29-year-old Zappavigna out of New South Wales, Australia. He enters this fight the winner of his last 10 contests, including his most recent triumph, a sixth-round stoppage of Ik Yang in July.

A highly regarded prospect with an exciting style, the 21-year-old Lubin burst onto the scene looking to finish opponents early as he cements his status as an elite contender. Fighting out of Orlando, he has already taken down experienced veterans including Orlando Lora, Ayi Bruce, Michael Finney and Norberto Gonzalez. He was sensational in November 2015 when he knocked out Alexis Camacho and in January he headlined his first card and dominated Jose De Jesus Macias in his first 10-round bout. He has kept the hot streak going in June by stopping veteran Daniel Sandoval in the third round and dominating veteran Ivan Montero in July.

A tall junior lightweight at more than six feet, the 21-year-old Barrios picked up seven victories in a jam-packed 2015 in which he stopped five opponents inside the distance, including an uppercut left hook combo that ended the night for Manuel Vides last December. The San Antonio-native turned pro in 2013 and is on the fast track towards a world title shot as he most recently defeated Devis Boschiero in a title eliminator in July. Now he looks to stay unbeaten in a matchup against Tapia out of Mendoza, Argentina.
