Day Seven of the U.S. Open Squash Championships presented by Macquarie Investment Management saw four quarterfinal matches on the ASB Glass Court at Philadelphia’s Drexel University as the semifinalists in the top halves of the Men’s and Women’s PSA World Series draws were decided.

The first match of the day produced a big upset as Nour El Tayeb beat top seed and world No. 1 Nour El Sherbini in a four-game all-Egyptian clash.

Two time champion Laura Massaro made it five U.S. Open semi-finals in seven years as she came from a game down to beat Annie Au, setting up a semifinal with Tayeb.

Nick Matthew’s impressive U.S. Open form continued as he reached a seventh consecutive final with a tough three-game win over fellow Englishman Daryl Selby.

Matthew will meet defending champion Mohamed Elshorbagy in a repeat of last year’s final after the Egyptian maintained his unbeaten record against Simon Rosner, although the second seed was taken to extra points in both the first two games.

Thursday is the second of two quarterfinal days starting at 4:30pm local time.
