Day Six of the U.S. Open Squash Championships presented by Macquarie Investment Management saw eight more second round matches on the ASB Glass Court at Philadelphia’s Drexel University as the quarter-finalists in the bottom halves of the Men’s and Women’s PSA World Series draws were decided.

Defending women’s champion Camille Serme crashed out in five games to Joelle King, who found the backwall nick on her fifth match ball. She now meets Alison Waters, the English eighth seed who also needed five games to end home interest as she beat U.S. Champion Olivia Blatchford.

An Egyptian semi-finalist is assured with second and fifth seeds Raneem El Welily and Nouran Gohar through after victories over Tesni Evans and Joshna Chinappa.

The men’s matches started with a big upset as Peru’s Diego Elias beat sixth seed Marwan Elshorbagy in a clash of two double world junior champions. He’ll now meet another Egyptian after 2015 finalist Omar Mosaad beat New Zealand’s Paul Coll in an impressive three games.

As with the women, an Egyptian semi-finalist is guaranteed after Fares Dessouki came from a game down to beat Alan Clyne and fourth seed Ali Farag finished strongly to beat compatriot Mazen Hesham in five games.

Wednesday is the first of two quarterfinal days starting at 4:30pm local time, while the community celebrates Character in Sports Day.
