Mathieu Castagnet produced his second successive upset at the Professional Squash Association (PSA) Canary Wharf Classic in London today as he beat seventh seed Fares Dessouky of Egypt 5-11, 11-7, 11-7 to earn a place in tomorrow's semi-finals.
This tournament has been a happy hunting ground at times for the 32-year-old Castagnet in the past, with victory over Egypt's Omar Mosaad in the 2016 final seeing him win his biggest title on the PSA Tour.
A string of injuries have seen the Frenchman slide down the rankings from a career-high world number six, but he rolled back the years at East Wintergarden yesterday to earn his first win in seven attempts against the German second seed Simon Rösner.
The best of three games format - which is being trialled in Canary Wharf for a second successive year - looks as if it is suiting him very well.
Castagnet will next meet New Zealand's fourth seed Paul Coll, who beat Joel Makin of Wales 11-9, 12-10 in the last of today's quarter-finals.
On the other side of the draw, defending champion and top seed Mohamed Elshorbagy of Egypt, the former world champion, moved imperiously through to the semi-finals with an 11-9, 11-2 win over home player Declan James that took two minutes short of half an hour.
Elshorbagy will next meet his compatriot Tarek Momen, who lived up to his third seeding as he won his quarter-final against the eighth-seeded Ryan Cuskelly, although the Australian made him work hard for an 8-11, 13-11, 11-5 win.
