While the top five seeded players in the Delaware Investments U.S. Open all progressed to the quarter-finals, it was the sixth, seventh and eigth seeds who crashed out of the World Series event at Drexel University, Philadelphia yesterday.
Number seven seed Nour El Sherbini was the first player to fall foul in round one, as qualifier and world No.12 Joelle King fought through a tough first game to close out a three-game win over the sixteen-year-old teenager.
In a similar contest, No.6 seed Annie Au also crashed out of proceedings, falling to last year’s U.S. Open runner-up Kasey Brown of Australia. Brown led after a first game tiebreak went in her favour and continued to stay ahead of the Hong Kong international to advance to the next round.
Completing the trio of upsets was returning world No.8 Alison Waters who came out on top after a cat-and-mouse affair against experienced Dutch player Natalie Grinham. The five-game encounter was laid to rest by Waters after 53-minutes of play, and the Englishwoman will progress to face top seed Nicol David, whom she beat in the Carol Weymuller Open quarters in New York last month.
David played out a lengthy three-game contest against qualifier Camille Serme of France, and the Malaysian will be ever focussed to claim the title she missed out on last year, more so after failing to win her last two WSA World Tour competitions.
Number two seed Raneem El Weleily put down the spirited efforts of Malaysian Low Wee Wern in four games. The Egyptian, who last month claimed the CIMB Malaysian Open, will face Kasey Brown in the quarter-final round.
Third seed Jenny Duncalf took just over half an hour to dispatch former world No.1 Rachael Grinham in a straight-forward three games. The Englishwoman will now face qualifier Joelle King in the quarters, having never lost the Kiwi.
Completing the last 16, No.4 seed Laura Massaro will face fifth seed Madeline Perry after defeating local wildcard Kristen Lange in a simple three game match. Perry progresses after clinching a four game victory over qualifier Donna Urquhart.
Tonight’s quarter-finals will be aired live on PSASquashTV.com as will the rest of the WSA matches in this event.
