The surprising result also showed that the India duo's win over the formidable combine in a tri-nation tournament in Malaysia was no fluke.
After their match against Canada, Ghosal, who became the first Indian to reach the semifinals at the Games, said: "It has been decent. Samantha and Shawn are actually really good players so, yes, it's been an impressive win and we were really focused on having a really hard match and I think both of us played quite well. We co-ordinated and adapted the game plan pretty well."
