Egypt's Ramy Ashour upset the seedings for the second time in 24 hours when he beat world No3 Gregory Gaultier in the final of the Delaware Investments US Open to win the PSA World Series event at Drexel University in Philadelphia for the first time.

The straight games triumph also marks the 25th PSA Tour title of the 25-year-old's career - a remarkable 17 of which have been World Series events.

World No4 Ashour reached his 40th Tour final after beating English rival Nick Matthew, the world No2 - while Frenchman Gaultier also took out an Englishman, James Willstrop, the world No1, in the other semi.

Ashour, playing with the speed and control with which he wrapped up his semi-final, was quickly 6-3 up in the opening game of the final, and took it after just six minutes.

Gaultier fought back from 1-6 down in the second to draw level at nine-all - but Ashour found two winners to extend his lead.

After an even start to the third, Ashour raced from five-all to 9-5, and although Gaultier again pulled back - going on to save two match-balls - it was a Gaultier volley into the tin that gave the Egyptian the title for the first time.

"I lost in this final three years ago so to win a prestigious title like this against such a great player as Greg feels just unbelievable," said Ashour, the fourth successive Egyptian winner of the title. "I felt good on court tonight but I had to fight really hard to win.

"It's been a great week, everyone here does a tremendous job and makes us all feel so welcome, so thanks to everyone involved and we're all looking forward to next year already!"

Ashour's 11-4, 11-9, 11-9 victory also takes him to the top of the 2012 Dunlop PSA World Series Standings - 10 points ahead of Matthew. Both have won two World Series titles in 2012, but Ashour has made the final in all of the four in which he has competed. Willstrop slips down to third place - again only 10 points behind Matthew - while Gaultier strengthens his grip on fourth place.

[4] Ramy Ashour (EGY) bt [3] Gregory Gaultier (FRA) 11-4, 11-9, 11-9 (43m)
