Unseeded Dane Line Hansen claimed the only upset on the opening day of the Women's Vassar College Class of 1932 Squash Open when she beat Malaysia's No7 seed Sharon Wee to earn a surprise place in the quarter-finals of the WISPA World Tour Silver event in Poughkeepsie in the US state of New York.
The 24-year-old from Odense recovered from a game down to take a 2/1 lead. But Wee fought back to level the match, then saved a match-ball at 8-4 in the decider to close the gap to just a single point.
Hansen held out, however, and clinched the match 6-9, 9-4, 9-7, 5-9, 9-7.
The Dane will now face England's Jenny Duncalf, the third seed from Yorkshire who beat New Zealand's Louise Crome 2-9, 9-2, 9-2, 9-5.
Event favourite Rachael Grinham was given a scare when fellow Australian Amelia Pittock, a qualifier, took the second game to level the score in their first round match. The three-time British Open champion upped the pace, however, and prevented Pittock from scoring a further point, winning 9-4, 7-9, 9-0, 9-0!
