Whilst Malaysia's Nicol David continues to head the Women's World Squash Rankings by more than a one thousand point margin, Ireland's Madeline Perry celebrates a career-high world No5 ranking in the September list published by the Women's International Squash Players' Association (WISPA).

Perry, the 33-year-old from Belfast who boasts 11 national titles, enjoyed the best month of her international career in August when she scored her biggest success at the Australian Open, winning the WISPA Gold title in Canberra in stunning style.

The triumph, bringing her Tour title total to eight, takes Perry to her highest ranking since April 2006.

Kasey Brown consolidated her status as Australia's No2 by leaping two places to a best-ever eighth place. The 25-year-old from New South Wales was a quarter-finalist in the latest two WISPA Gold events, the Singapore Masters in July and Australian Open in August.

Egypt's Raneem El Weleily also has cause for celebration after making her top ten debut at No10. The 21-year-old from Alexandria recorded her best ever run in a WISPA Gold event in July when she reached the Malaysian Open semi-finals - as a qualifier!

And Nicol David is joined in the top 20 by a fellow Malaysian for the first time for more than two years as a result of Low Wee Wern making her debut in the elite group at No20.

Also from Penang, 20-year-old Low Wee Wern was an unexpected quarter-finalist in the Malaysian Open and qualified to make the main draw of the Singapore Masters.
