The Canary Wharf Classic title success in London last month has extended Englishman Nick Matthew’s (pic, le) lead at the top of the Dunlop PSA Men’s World Squash Rankings, according to the April list published today by the PSA. In an unchanged top ten, Matthew leads Egyptian rival Ramy Ashour, with fellow Egyptian Karim Darwish – winner of last month’s KL Open – in 3rd place, and England’s James Willstrop at No4. The first riser in the new list is David Palmer (pic ri), the illustrious Australian who is a two-time World Open and four-time British Open champion. Hisham Ashour, the 28-year-old Egyptian who beat Palmer to lift the National Bank Financial Group Open title in Canada, rises to a career-high No14. Top-10 (inc. points average): 1. Nick Matthew (ENG, 1,568); 2. Ramy Ashour (EGY, 1,296); 3. Karim Darwish (EGY, 989); 4. James Willstrop (ENG, 897); 5. Amr Shabana (EGY, 832); 6. Greg Gaultier (FRA, 782); 7. Peter Barker (ENG, 618); 8. Thierry Lincou (FRA, 557); 9. Mohamed El Shorbagy (EGY, 527); 10. Azlan Iskandar (MAS, 439).
