LAURA Massaro produced the form of her life to beat world number one Nicol David in the final of the Cleveland Raquet Classic.

The 27-year-old from Chorley stunned the Malaysian squash star with a four-game victory in the first tournament of the year in Ohio.

Massaro, who lives in Hoghton, had never beaten David – recently voted the world’s best player for the fifth consecutive year – in her nine previous attempts.

But the former Albany High School pupil produced four near perfect games to win 11-9, 11-7, 9-11, 11-8 and scoop the $55,000 prize fund.

“I thought I played the best I have ever played,” said Massaro a member for East Lancashire Squash Club in Blackburn.

“To win a Gold event with Nicol not even in it would have been some achievement.

“But to beat an amazing player who has won so much, it is the best result I have ever had.”

It completed a remarkable week for the world number nine, who pulled off a series of shock results on her way to victory in America.

Having defeated Egyptian Raneem El Weleily in the first round, Massaro beat fellow England international and world number two Jenny Duncalf in the quarter finals and then Ireland’s Madeline Perry, ranked fourth in the world, to reach the final.

It made it back-to-back tournament wins for Massaro, who ended 2010 by winning the Sharm El-Sheikh Classic.

But she ranks her Cleveland triumph as the best yet.

“This is the best achievement of my career,” she said.
