Egypt’s world number one Mohamed ElShorbagy and world number two Ali Farag both reached the quarter-finals of the CIB Black Ball Squash Open along with the other top seeds on day four in Cairo.

Reigning world champion El Shorbagy comfortably dispatched rising Malaysian star Eain Yow Ng in straight-games in this Professional Squash Association Platinum tournament at the Black Ball Sporting Club.

He will now face compatriot and former world number one Karim Abdel Gawad in the last eight after the latter overcame Peru’s Diego Elias.

“He’s 20-years-old and has potential to be a world number one one day and a world champion,” said ElShorbagy.

“This is the first time we play, but I told him we are going to play many times in the future.”

Farag continued with the impressive form that has seen him claim two titles so far this season as he beat world junior champion Mostafa Asal 11-4, 13-11, 11-3.

“Mostafa is such a great prospect for Egyptian squash,” said 26-year-old Farag.

Farag will now face India’s world number 12 Saurav Ghosal after he beat Egypt’s former world number three Omar Mosaad to reach his first quarter-final at a PSA Platinum event this season.

Germany’s world number three Simon Rösner survived a scare to reach the quarter-finals.

He faced defeat against Gregoire Marche after the Frenchman had built up a two-game lead.

However, Rösner’s class allowed him to come through 5-11, 9-11, 11-8, 11-5, 11-5.

He will now face New Zealand’s Paul Coll, who comfortably dispatched England’s Chris Simpson in straight-games.

The final quarter-final fixture will see an all-Egyptian battle between world number four Tarek Momen and world number 10 Mohamed Abouelghar.

Momen defeated Germany’s Raphael Kandra in straight-games, while Abouelghar overcame a resilient George Parker of England.
