WORLD SQUASH NEWS RESULTS: Bright Lights Women's Las Vegas Squash Open, Las Vegas, USA Quarter-finals: [1] Linda Charman (ENG) bt [6] Rebecca Chiu (HKG) 9-4, 9-0, 9-6 Lara Petera (NZL) bt [7] Sharon Wee (MAS) 3-9, 9-7, 9-4, 9-4 [3] Cassie Jackman (ENG) bt [Q] Melanie Jans (CAN) 9-2, 9-7, 9-6 [2] Vanessa Atkinson (NED) bt [8] Nicol David (MAS) 9-6, 8-10, 9-1, 8-10, 9-2 Wee Peters Out To Petera New Zealand's unseeded Lara Petera maintained her good form in the Bright Lights Women's Las Vegas Squash Open in the USA when she despatched seventh-seeded Malaysian Sharon Wee in a four-game quarter-final at ClubSport Green Valley in Nevada. The 24-year-old from Auckland, who knocked out fourth seed Annelize Naude in the opening round, beat Wee 3-9 9-7 9-4 9-4 and now meets England's top seed Linda Charman in the semi-finals Charman, the world No3 from Eastbourne in Sussex, defeated Hong Kong's Asian Games champion Rebecca Chiu 9-4 9-0 9-6. It was a bad day for Malaysia as twice world junior champion Nicol David also made her exit from the WISPA World Tour event, but not before taking her second-seeded opponent Vanessa Atkinson the full distance. David is playing in her first WISPA event since May last year - only two weeks after beginning a new training regime in the Netherlands with Australia's former world No2 Liz Irving, the Dutch national coach. The 19-year-old from Penang twice pegged back the Dutch No1 in a closely-contested tussle in Las Vegas, but Atkinson ultimately prevailed 9-6 8-10 9-1 8-10 9-2 to take her anticipated place in the last four. Her semi-final opponent will be England's British champion Cassie Jackman, the third seed from Norfolk who ended the run of Canadian qualifier Melanie Jans in a 9-2 9-7 9-6 scoreline. Whilst Jackman is seeded below Atkinson, the Englishwoman and former world champion has since risen above her opponent to six in the latest world rankings.
