Choi is early leader at Canadian Women's Open

LONDON, Ontario (AP) Na Yeon Choi of South Korea chipped in for three of her nine birdies and tied the course record at 8-under 64 for the early lead at the Canadian Women's Open.

She is two strokes ahead of Danielle Kang, LPGA Championship winner Inbee Park and Xi Yu Lin following the completion of morning groups at London Hunt and Country Club.

Choi, the 2012 U.S. Women's Open champion, birdied five straight holes. She finished one stroke short of her career-best of 9 under, which she shot in Waterloo, Ontario, last year.

She lipped out on a birdie putt on the ninth hole - her final one Thursday - with a chance to break the course record.
