SHOOTO continues its tradition of major Summer cards on August 20 when American Gilbert Melendez (pictures) fights Japanese icon Rumina Sato (pictures) in the main event at the Yokohama Cultural Gymnasium.

Sato, the SHOOTO 143-lb. Pacific Rim champion, specifically requested a fight versus Melendez and the Cesar Gracie-trained fighter happily accepted. The winner will likely earn the right to fight champion Alexandre Franca Nogueira (pictures) later this year.
