In the fifth match, Marrero Gang thrashed Samurai 7 4-1, thus eliminating them from WCT 3. In the last match of the tournament, UGen beat 2-1 Ape Escape in a close match. Since UGen and Marrero Gang were unbeaten in their 2 matches and the top teams on the group table, they qualified for the final. In a closely contested final, Marrero Gang won for a third consecutive year beating U-Gen by two evasions to one.
