Hannah Green had both momentum and luck on her side as she extended her lead at the Women’s P.G.A. Championship to three shots on Friday.
Green, a 22-year-old Australian, maintained her momentum from a superb opening round in which she needed just 23 putts. On Friday, she had 27 putts on the way to a three-under-par 69 and a seven-under total of 137.
Ariya Jutanugarn, the two-time major winner from Thailand, was alone in second after shooting 70 at the Hazeltine National Golf Club in Chaska, Minn.
Lydia Ko of New Zealand, who shot 70, and the defending champion, Park Sung-hyun, who shot 71, were tied for third at 141.
