OTTAWA, Ontario (AP) Marina Alex shot a 5-under 66 on Thursday to take the lead in the Canadian Pacific Women's Open, while Canadian star Brooke Henderson was in danger of missing the cut after a 74.

Alex had four birdies on her opening nine - the back nine at Ottawa Hunt - and added two birdies and a bogey on her second nine. The American is winless on the PGA Tour.

Henderson, from nearby Smiths Falls, struggled on the greens. The 19-year-old Canadian has four LPGA Tour victories, winning the major KPMG Women's PGA last year and the Meijer LPGA Classic in June.

South Korea's In Gee Chun and England's Holly Clyburn were a stroke back at 67.

Angel Yin and Brittany Lincicome, coming off the United States' Solheim Cup victory Sunday in Iowa, were at 68 along with Shanshan Feng, Sei Young Kim, Pavarisa Yoktuan and Sherman Santiwiwatthanaphong.
