England's James Willstrop marks up his tenth month as world number one according to the new November Dunlop PSA Men's World Squash Rankings, published today by the PSA.

The 29-year-old from Leeds maintains his lead over fellow Englishman Nick Matthew, the world No2 who celebrates his 35th successive month in the world's top three.

Both players bowed out at the semi-final stage of last month's US Open, the fifth PSA World Series event of the year in Philadelphia - where Egypt's Ramy Ashour triumphed to win his second World Series crown of 2012.

The 25-year-old from Cairo moves up to No4 in the new rankings - but Frenchman Gregory Gaultier, the US Open runner-up, holds onto third place.

Egyptian Mohamed El Shorbagy, the youngest player in the top 20, also moves upwards - to No7, just one place below his career-best position. The 21-year-old from Alexandria reached the quarter-finals in Philadelphia before going down to Willstrop (both pictured above) in a 90-minute five-game thriller.

Daryl Selby leapfrogs Egyptian Omar Mosaad to reclaim a place in the world top ten after a six-month absence. Selby's move also restores the balance of the top ten to four of both Englishmen and Egyptians.

But the highest-placed player to boast a career-high ranking is German Simon Rosner. The 24-year-old from Paderborn picked up the sixth PSA World Tour title of his career in last month's Santiago Open in Spain, where he upset local hero and defending champion Borja Golan to reach the final against expectation.

Finland's Olli Tuominen makes a welcome return to the world's top 20 for the first time for over a year following his fourth title success in the Finnish Open earlier in the year.
