They extended the lead to seven in the sixth, both Jared Cruz and Jarryd Dale bringing home runners.
On a bright note for the Cavalry, Canberra product Logan Kingham's first ABL at-bat produced the visitors' opening run of the game - scoring David Kandilas.
But Melbourne just inflicted more pain on the Cavalry, George hitting a home run to start a three-run Aces inning.
Kandilas added another consolation run for the Cavalry in the eighth, before the Aces added another, and then Kingham crossed the plate himself in the top of the ninth.
Aside from Kent, who starred on Friday night, Canberra's other two starters struggled.
