Natalie Grinham retains her position as World No.2, but her older sister Rachael Grinham slips to four as US star Natalie Grainger rises to third place - her highest position for more than four years. 
Vicky Botwright's remarkable run in Manchester - on her 'home' court at the National Squash Centre in her final event before retiring from the WISPA World Tour - has catapulted the 31-year-old to seventh place in the new list, only two positions lower than her career-best ranking.
Lower in the list, New Zealand's Jaclyn Hawkes celebrates a career-best No.16 ranking. The 25-year-old from Auckland achieved one of the best runs of her career in last month's World Open, dismissing two higher-ranked opponents to reach her maiden quarter-finals.
Hong Kong teenager Annie Au is poised to become the youngest player in the top 20 after leaping seven places to No.21. The 19-year-old became the only qualifier to reach the last sixteen after upsetting Mexico's World No.18 Samantha Teran.
