In her first ever victory over the world number two, England's Laura Lengthorn-Massaro today (Thursday) beat second seed Natalie Grinham in the CIMB KL Open to claim an unexpected berth in the semi-finals of the $53,000 WISPA World Tour Gold squash event in the Malaysian capital Kuala Lumpur.
Only days after celebrating a career-high world No7 ranking, the 25-year-old from Lancashire beat Grinham junior, now representing the Netherlands, 11-6, 11-9, 11-6 to record one of the finest wins of her career.
Grinham, runner-up for the past two years, was still suffering the after-effects of whooping cough - and had only recently returned to full-time training.
The win takes the eighth seed through to a clash with another Natalie - Pan American Games gold medallist Natalie Grainger. The fourth seed from the USA took four games to overcome Egyptian star Omneya Abdel Kawy 11-5, 11-5, 9-11, 11-9.
Local heroine Nicol David did not have it all her own way at the top of the draw. The top-seeded Malaysian, going for her sixth title, won the first game against Jenny Duncalf and led 10-6 in the second. But the fifth seed from England held her nerve to level the match before David raised her game to record an 11-1, 10-12, 11-7, 11-9 victory after 46 minutes.
World number one David will now take on Rachael Grinham for a place in the final. The third seed from Australia was taken the full distance by Alison Waters before ultimately beating the sixth seed from England 11-9, 4-11, 10-12, 11-8, 12-10 after 63 minutes.
