As early as the 3rd minute Ademilson struck post with a left foot shot after some good work from Shinya Yajima has helped create the chance and then Yajima himself, exchanging passes with Usami, half volleyed just wide on the follow up attempt, but it was not long before Gamba broke the deadlock, as Onose volleyed home a half-cleared corner to give his team the lead in the 9th minute.
In the 26th minute Ademilson closed down a defender trying to bring the ball out for the back and advanced on goal, getting a blistering shot off from the edge of the area that the 'keeper could only parry away to safety but Gamba did add to their tally just before the break as Yasuhito Endo moved forward, exchanged passes with Usami before the latter sent an unstoppable right foot blast into the top of the net to give the away team a 2-0 half time lead.
Usami then added his second goal of the game just after the restart, when a long ball from the left back position was won by the in-form striker, who strode on and then hit a superb shot past the helpless home goalkeeper to make it it 3-0. The badge was kissed.... game over! But even then Gamba went looking for more goals and substitute Kazuma Watanabe came close just minutes after coming on, seeing his low shot saved at the post for the under fire 'keeper.
And so, that's how it ended, with a clean sheet for the rarely troubled Masaaki Higashiguchi in the Gamba goal, and another three points and adding to a run that has seen them lose just three games in the 19 since mid-May - all of those losses being against teams in the current top five. The future looks bright for Tsueyasu Miyamoto's squad as we start looking to 2020.
