Ko, who stumbled early with bogeys on three of the first six holes, birdied three of the final six - including the 18th after almost pitching in for eagle - for a 71 that tied her with Lee.

For Ko, the friendly confines of Lake Merced Golf Club could be just the place to end her drought.Although Ko had 11 top-10 finishes across the 2017 season but has looked a far cry from the fresh-faced teenager who tore the scene apart back in 2015.
"I knew I needed to hit it actually good to hold the tree and to succeed in the inexperienced, particularly with Minjee being a superb 20 yards in entrance of me and it seemed like she was going to hit an iron", stated Ko, who was born in Seoul, South Korea however moved to New Zealand as an toddler. I think sometimes self pressure is the biggest thing where you kind of put a lot of load on your shoulders.
