Canadian Brooke Henderson remained bogey-free to take the Lotte Championship lead halfway through the second round Thursday.
Henderson, who hails from Smith Falls, Ont., shot a 6-under 66 in 15 mph morning wind at Ko Olina Golf Club to get to 10 under. Ranked 14th in the world, the 20-year-old won twice last year and has five career LPGA Tour victories.
Mo Martin, the 2014 Women’s British Open champion, was two back after a 67.
Pernilla Lindberg and Inbee Park were back together again on the leaderboard at 6 under, two weeks after Lindberg beat Park on the eighth extra hole in the major ANA Inspiration. Lindberg shot 68, and Park had a 69. Lindy Duncan also was 6 under after a 68.
