Gabriel Arges was the man of the hour, looking absolutely untouchable all the way through the event. His semi-final with Jaime Canuto a technical back-and-forth war. He finished the day a savage RNC submission victory over Matheus Souza. Arges' momentum from 2016 is seemingly cruising right through into the new year.
Stand out performances from the day also include Marcio Andre, Xande Riberio and Nathiley de Jesus - all took gold in their respective divisions.
Final note: Paulo Miyao Mysteriously dropped out of competition -we will update when more information a out his departure comes through.
