When Lydia Ko stepped on the tee box at the par-4 18th hole Saturday at Vancouver Golf Club, she hadn't recorded a bogey in 46 holes.
However, after missing a 10-footer for par, Ko bogeyed the closing hole of her third round at the Canadian Pacific Women's Open, and instead of leading outright entering Sunday's final round, a 3-under 69 left her at 12 under and tied with Candie Kung for the 54-hole lead.
Kung, who tied the course record with a second-round 64, shot 71 on Saturday. Alison Lee is third at 10 under, two shots back.
