Jenaya Wade-Fray and her Standard Life Great Britain Women's teammates defeated world ranked number 11 side, Canada, 70-57 at Edinburgh's Meadowbank Sports Centre in their first appearance on home soil this summer.
Wade-Fray played only 1:28, going 0 for 2 from the Free Throw Line, she grabbed 1 Rebound and committed 1 Foul in her time on the Court.
Natalie Stafford hit a team-high 16 points as the hosts rallied from 28-24 behind at half-time to deliver their most impressive performance so far of their Olympic build-up.
Standard Life Great Britain head coach, Tom Maher, admitted he would settle for a similar showing when the sides meet again tomorrow: "I am delighted, I won't lie. Our performance was terrific against a team we need to be able to cope with. When you look at world rankings, they're in the mix for the Olympics. These are the kind of teams you want to compete against."
Great Britain made an early impression, leading for much of the opening quarter but the Canadians used a 7-0 run to move ahead early in the second period.
However, Maher's side raised their game after the break, with young internationals Temi Fagbenle and Dominique Allen impressing defensively as Allen grabbed a team-high seven rebounds. Familiar faces Jo Leedham, who added 15 points and six rebounds, and Stafford also shone as they sparked Britain's scoring surge.
An 11-2 run midway through the third pushed GB ahead for good as they surged 52-43 in front with eight minutes left.
Canada, paced by 19 points from ex-WNBA forward Kim Smith, used an 8-2 flurry to come within three but their revival ended there.
In the final minutes the hosts went clear as ten consecutive free throws from Great Britain propelled them away.
Lead scorer, Stafford commented on the win: "Today was much much better. We came out and had a fantastic start, it was our defense that got it. We knuckled down and communicated well. We switched well and we played more consistently than in the first few games.
"We won, but there is always room for improvement. We got caught up at times when they were running their offense and getting easy baskets. For us, it's about getting that consistency now."
Edinburgh's own Rose Anderson added four points and two rebounds while Fagbenle had 11 points.
