World number one Elshorbagy appears to have put his shock second round defeat at last month’s Hong Kong Open firmly to the back of his mind as he secured a straight games win over Mathieu Castagnet.

The French player gave Elshorbagy a stern challenge in each game but the Egyptian emerged unscathed with an 11-9, 11-8, 11-8 victory.

Elshorbagy will now face Borja Golan in the semi-finals after the Spaniard beat Australia’s Cameron Pilley 11-8, 6-11, 11-8, 11-4.

Reigning world champion Gaultier proved untroubled by Egypt’s Tarek Momen in the first two games of their match, winning 11-3, 11-5.

He was made to work harder in the third, but ultimately took the game 14-12 to seal victory and a semi-final spot.

Gaultier will face another Egyptian, Karim Abdel Gawad, who won the tightest match of the day 11-9, 11-3, 8-11, 5-11, 11-9 against India’s Saurav Ghosal.

"I’m very happy that I managed to win in five after I was 2-0 up and he managed to come back," said Gawad, the world number six.

"He played some unbelievable squash and is such a great player so all credit to him."

Top seed Laura Massaro enjoyed straightforward progression to the women’s semi-finals, the Englishwoman winning 11-7, 11-5, 11-6 against India’s Joshna Chinappa.

Massaro’s compatriot Alison Waters appeared on course for a shock victory when she claimed the opening game of her match against Raneem El Welily.

The second seeded Egyptian hit back to win the next three games and secure a 9-11, 13-11, 11-9, 11-4 victory.

El Welily will face Nouran Gohar, who won an all-Egyptian quarter-final match with Salma Hany Ibrahim by a 9-11, 11-5, 12-10, 11-8 scoreline.

New Zealand’s Joelle King won her quarter-final match with England’s Sarah-Jane Perry by 11-8, 8-11, 11-9, 13-11.

She will now take on Massaro for a place in tomorrow's final.
