A right hook by the Thai world champion dropped Chocolatito hard in round four. He managed to get up but Rungvisai attacked as the right hook found its mark knocking Gonzalez out cold as the referee Thomas Taylor immediately waived the bout at 1:18 of the fourth.
Making his United States debut in the co-feature WBO super flyweight world champion Naoya “The Monster” Inoue (14-0, 12 KOs) of Yokohama, Japan as he stopped top contender Antonio “Carita” Nieves (17-2-2, 9 KOs) of Cleveland. Inoue dropped Nieves with a crunching left hook in the fifth punishing him throughout the fight as his corner had seen enough between the sixth round and seventh round.
Opening up the HBO telecast former WBA and WBO flyweight champion Juan Francisco Estrada (36-2, 25 KOs) won a twelve-round unanimous decision over former WBC super flyweight champion Carlos Cuadras (36-2-1, 27 KOs) after ringside announcer Michael Buffer had his Steve Harvey moment mistakenly announcing the decision for Cuadras.
