Nicol David in cruise control in Glasgow

David, the world's top player since 2006, made it through to the last eight with an 11-7, 11-6, 11-5 win.

"It was good to be out there playing better squash. Megan has been playing well and it was my first time playing her so it's good to just get a feel of how she plays in the first game and then I got my bearings on the court, just feeling the court better as the match went on so I was really pleased with that," David said.

"It's fantastic to see, even from the first round and the crowds just keep getting better and to have the whole Malaysia crew cheering me on is always great.

"You feel that you're part of something special. You definitely grow into the tournament. This is the second round and you just want to be out there after the hype and it's a great feeling to be out there.

"My quarter-final will definitely be a step up and I'll have to bring my A-game."

New Zealander Joelle King secured her place in the quarter-finals with a four-game win over India's Joshana Chinappa.

The world number four took a two-game lead with 11-3 and 11-8 wins but Chinappa, ranked 11 in the world, fought back to win the third 11-8.

But despite some over-zealous support for her opponent from the crowd, King gathered herself to respond and win the fourth game 11-5.

King won gold in the women's doubles and silver in the mixed doubles in

Delhi four years ago and the third seed felt the match was a good test of her game and mental strength.

She said: "I started off really well and had a patch where Joshana really came back and had a bit of momentum but I relaxed again in the fourth and got the win.

"I'm actually really happy about that match. There were a few things that were happening as well as Joshana coming back at me and she started playing some really good squash so I'm just happy I was able to finish well and hopefully I can carry that through to the next round."
