Malaysia's world number two Datuk Nicol David advanced to the quarterfinals of the 2015 US Open Squash championship held at the Drexel University Daskalakis Athletic Center in Philadelphia Tuesday.

According to the competition's official website, www.usopensquash.com, the three-time defending champion is on track to retaining her title after making up for the September China Open defeat to world junior champion Nouran Gohar.

Nicol took just 34 minutes to beat her Egyptian adversary 11-6, 11-7 and 11-7.

"She's certainly a strong competitor and she's been doing really well the past few months," Nicol was quoted as saying by the website.

Nicol has set up a repeat of the 2013 US Open final against England's Laura Massaro in the quarterfinal on Oct 15. Such quarterfinal matchups are testament to the strength of the tour.

"It's great. As you can see, everybody is really picking up their game. Facing Laura in the quarterfinals is a treat for the crowd," said Nicol.

Laura booked her berth in the last eight after defeating homester Amanda Sobhy 11-8, 7-11, 11-4 and 11-9 in a 49-minute match.
