Canadian Hollie Naughton is the only non-seeded player to advance through to the quarter finals of the Cleveland Classic.
The World No.36 overcame Nadine Shahin in the second round, winning out against the tournament’s No.8 seed in five, coming from behind after losing the first game.
Shahin was the only Egyptian to lose, with three players making it through to the last eight from the country.
Mayar Hany and Mariam Metwally both won their games in four, against Amanda Landers-Murphy and Coline Aumard respectively.
Meanwhile, it was much easier for World No.4 Nour El Tayeb, who took less than 20 minutes to beat Malaysian Rachel Arnold.
The other four players through to the last eight of the Cleveland Classic are all from Great Britain.
Tesni Evans (l) in action against Danielle Letourneau
Tesni Evans, the World No.11, and lone Welshwoman in the tournament, eased past Danielle Letourneau in four to book her place in the quarter finals.
Joining her are three women from England. Alison Waters also overcame Canadian opposition, in the form of Samantha Cornett.
Elsewhere, Victoria Lust beat Lisa Aitken in a five-game battle of Britain, while Emily Whitlock defeated Nele Gilis in straight games.
None of the Brits will meet in the quarter finals, with Waters up against the non-seeded Naughton. El Tayeb will face Whitlock, Lust will play Metwally, and Evans will go up against Hany.
