Egypt's Karim Darwish moves into his eight month as World No.1, according to the new August Dunlop PSA Men's World Squash Rankings, published by the Professional Squash Association.
The 27-year-old from Cairo maintains his lead ahead of Frenchman Gregory Gaultier, who holds onto his career-best position of number two.
In an unchanged top eight, Egypt's 21-year-old World Open champion Ramy Ashour remains in third place - with compatriot Amr Shabana, the three-time world champion, at No4.
But Londoner Adrian Grant is one of two Englishmen celebrating career-best rankings in the new list: The 28-year-old left-hander, who boasts more PSA World Tour titles than any other current compatriots on the Tour, rises to No9 - his first ever single-figure ranking.
Grant won his 16th Tour title at the Indian Challenger No2 in Kolkata in March - but was forced to withdraw from this month's CIMB Malaysian Open due to a calf injury.
Alister Walker, the Botswana-born 26-year-old who made his England senior international debut in April, jumps two places to a career-high world No14. Walker claimed his third Tour title at the Midtown Sanctuaire Open in Montreal in February.
Dutchman Laurens Jan Anjema is also celebrating a career-best ranking after a two-place jump. The 26-year-old from The Hague reached his 21st PSA Tour final at the Internationaux de la Reunion in France in June - a week after claiming his eighth title at the Toulouse Open.
Two players also mark their return to the world top 20: Australian Cameron Pilley, out of the elite group for four months, secured an unexpected berth in last month's final of the Australian Open - and leaps three places to 19.
Olli Tuominen, the highest-ranked Finn throughout this decade, slips back into the top 20 at No20 after a three-month absence. The 30-year-old from Helsinki delighted local fans in February when he upset favourite Stewart Boswell to win the Savcor Finnish Open for the second year in a row.
