Donna Urquhart is through to her first women's singles quarterfinals after defeating fellow teammate Christine Nunn 3-2 in the Round of 16.
Urquhart has only progressed to the quarterfinals in the mixed and women's doubles in the Commonwealth Games previously
"I've got to pinch myself for a few minutes," she said.
"I'm really looking forward to staying in the tournament and playing in front of a friendly crowd."
It was a tough match between the two Australians as it went down to the wire in the fifth game as it was two apiece for the athletes.
It was even tougher as the two have usually been doubles partners and have never played against each other at a tournament.
"I'd much rather be watching Christine and cheering for her," Urquhart said.
"It's really unfortunate that we have to play each other but I think for both of us we have a mutual understanding that as opponents we put our game face on and just get on with it," she said.
It was only four years ago when Urquhart was dropped from the singles team ahead of Glasgow 2014 and replaced by Sarah Cardwell as Squash Australia believed her best chance of winning a medal was the doubles competition.
Urquhart says the win today means everything after what happened in Glasgow and was happy to have her cheer squad in the crowd.
"More than anything my family and friends are here watching and they don't get to do that very often," she said
"I knew they were here today and I could hear them cheering and I think that helped me a little bit to get over the line."
Urquhart will face world number eight Sarah-Jane Perry tomorrow.
