For the first time in eighteen PSA matchups, Annie Au defeated three-time U.S. Open champion Nicol David. The five-game result also marked the Hong Kong international’s first career win on the U.S. Open ASB GlassCourt. The men’s draw included the longest match of the tournament so far in which Daryl Selby upset seven seed Tarek Momen in five games after one hundred and two minutes.

In the women’s draw top seed and World #1 Nour El Sherbini enjoyed a quick win over an injured opponent, setting up an all-Egyptian quarter-final with tenth seed Nour El Tayeb, who beat fellow Egyptian Salma Hany in four tough games.

Two-time champion Laura Massaro won an all-English tussle with Emily Whitlock to reach her 9th straight U.S. Open quarter-final, where she’ll meet unexpected opposition in the form of Au.

Men’s defending champion Mohamed ElShorbagy continued his impressive start to the tournament with an interrupted four-game win over fellow-Egyptian Mohamed Abouelghar, and he’ll meet Simon Rosner for a place in the semis after the German ended the run of Mexico’s Cesar Salazar in four.

Day Six will see the quarter-finalist in the bottom halves of the draws on Tuesday, starting at noon, while the community celebrates Women in Sports Day.

Watch all of the action on SquashTV from noon local time.
