No stopping Pattersen in Canada

Suzann Pettersen defied windy conditions to maintain her good form and take a five-stroke lead in the CN Canadian Women's Open.

The Norwegian started the day in a tie for first with Song-Hee Kim but her five-under-par 66 and a shocking six-over-par 77 by the South Korean saw Pettersen take an outright lead.

Pettersen had just one bogey but shot six birdies despite the gusty conditions to stand five shots ahead of Angela Stanford in second place.

Pettersen told www.lpga.com: "It seems like the harder conditions, the more creative I get with my shots and kind of trying to take control of the ball flight, and I keep rolling the putts in.

"So you have got to take the chances when you have them."

Pettersen dismissed the notion she would take a conservative approach with such a healthy advantage.

"That's not really my personality, to be honest," she added.

"I have a number in my head.

"I'm not there yet, so I have got to make some birdies tomorrow to get there, and we'll see what that brings me."

Stanford began the day in a tie for fifth but rose to second after a two-under-par 69 with Karrie Webb one place back with a three-under-par 68 and Lorena Ochoa and In-Kyung Kim in a tie for fourth.

Great Britain's Catriona Matthew, third after the second round, could only muster a four-over-par 75 to drop to a tie for 12th.
