The Aces started the game in hot form as utility Scott Wearne led off with a triple and they never looked back after taking the lead in the first inning.
Backed by a strong performance from import Hirotaka Koishi, who pitched a complete game, the result was never in doubt as he restricted the visitors to just five hits as he struck out nine.
Elliot Biddle and Jarryd Rogers both picked up multiple hits in the first game of the double header, as the home side showed great efficiency, collecting their 5 runs on just 8 hits.
Melbourne was unable to pick up where it left off as Canberra scored twice in the opening frame of the second game of the day.
The man of the hour for the Aces appeared to be Brad Harman, who homered in both the fifth and the ninth, to keep the Aces in touch with the Cavalry, who had a comfortable four run lead coming into the final inning.
The comfort was shattered when Josh Davies stepped up to the plate and put a no-doubter over the left field fence to ensure that at worst the game would head to extra innings.
Speaking post-game, Davies stressed the importance of getting consecutive hits.
"We've had a couple of times where the timely hitting hasn't been there, but the fact it is shows that there is a positive for us to look forward to tomorrow."
It wasn't enough for the Aces as Jeremy Barnes crunched a solo shot in the top of the tenth, handing the visitors a 9-8 lead, a lead they would not relinquish.
Despite the loss Davies was adamant that it wasn't all doom and gloom in the Aces camp.
"It was a good fightback, we did well just to get back, but one of their guys got a hold of one in the top of the tenth and that's just how it goes."
