Australian Cameron Pilley and Egypt's Hisham Mohd Ashour produced notable upsets in the $192,500 Punj Lloyd PSA Masters to claim unexpected places in the quarter-finals of the tenth and final PSA Super Series squash championship of the year at the Sirifort CWG Block in the Indian capital New Delhi.
Ashour, the 14th seed and older brother of injured world number one Ramy Ashour, twice came from behind to defeat seventh-seeded Dutchman Laurens Jan Anjema, the world No9, 6-11, 11-6, 9-11, 11-8, 11-6 in 59 minutes.
Celebrating his first appearance in a Super Series event quarter-final this year, the world No29 from Cairo will now meet Frenchman Thierry Lincou. The fourth seed from Marseille reached his ninth quarter-final in a row when he beat Finland's 13th seed Olli Tuominen 14-12, 11-8, 11-2.
Tenth seed Pilley dropped the first game to Wael El Hindi, the sixth seed from Egypt who needed a good performance in New Delhi to be sure of a place in next year's ATCO PSA World Series Finals in London.
But the world No15 from New South Wales battled back to take the next game, then survived a close third game in a tie-break before El Hindi conceded the match after pulling a calf muscle.
Pilley's 7-11, 11-3, 14-12 (ret.) win takes him through to a clash with James Willstrop, the second seed from England who dismissed Egypt's No11 seed Omar Mosaad 11-7, 11-6, 11-9.
England's Daryl Selby also gained an unexpected quarter-final berth when his opponent and England team-mate Peter Barker, the fifth seed, was forced to concede the match - without striking a ball - as the result of a back injury.
Selby, the ninth seed, will now face another England team-mate Nick Matthew, the top seed and newly-crowned world champion, in a match which has major significance for both players.
A win for Matthew will ensure his return to the top of the world rankings next month - and success for Selby will signal his first appearance in the World Series Finals.
