The top eight seeds in both the men's and women's draws will contest the quarter-finals at the Professional Squash Association (PSA) World Championships.

Third round matches concluded today at the University of Chicago with the flagship tournament so far producing no major upsets.

In the men's draw, Egypt's second seed Mohamed ElShorbagy marched through to the last eight after a 11-4, 11-7, 11-7 victory over Joel Makin of Wales.

The 2017 world champion knows that he will become world number one if he reaches the final in Chicago, regardless of what current rankings topper Ali Farag does.

ElShorbagy and Makin practice together regularly so know each other's games well.

"I definitely stayed away from him yesterday, I ran away from our practice together," said ElShorbagy. 

"We practiced together today and he was literally volleying everything, he was playing together so fast, and I didn't want to play that fast. 

"You have to do what you have to do to play tournaments right now."

ElShorbagy will now play seventh seed and compatriot Fares Dessouky in the quarter-finals after he beat another Egyptian, Mohamed Abouelghar, 11-6, 11-13, 11-7, 12-10.

New Zealand's fourth seed Paul Coll, the runner-up at the 2019-2020 edition in Doha, defeated India's Saurav Ghosal 11-3, 7-11, 11-5, 11-5 to advance.

He will play Egypt's sixth seed Karim Abdel Gawad, the 2016 world champion who came from behind to knock out France's Baptiste Masotti 8-11, 11-0, 11-7, 11-4.

In the women's draw, Egypt's second seed Nouran Gohar continued her progression by beating Tesni Evans of Wales 12-10, 11-4, 11-8.

"Tesni is a very tricky player and it is never easy to play against her," said Gohar.

"She is relaxed but very eager to win so it is tricky."

Gohar will play New Zealand's Joelle King, the seventh seed who beat Nadine Shahin of Egypt 11-8, 11-3, 11-5.

French third seed Camille Serme ended the hopes of home American player Olivia Clyne with a 11-8, 11-7, 9-11, 11-8 success.

Her reward is a date in the quarter-finals with eighth seed Salma Hany, who won an all-Egyptian contest against Rowan Elaraby, 8-11, 11-4, 11-4, 11-6.

The last eight matches begin tomorrow.
