Brooke Henderson shot a 6-under 65 on Friday in the North Texas Shootout, giving the 17-year-old Canadian the lead going into the weekend for the second straight week on the LPGA Tour.
Henderson had a bogey-free round to reach 8-under 134 total at Las Colinas, a stroke ahead of 2013 winner Inbee Park and 54-year-old Juli Inkster.
Denied a waiver to the LPGA Tour's minimum-age requirement of 18 last year, Henderson earned the last spot in the field Tuesday in a playoff in the qualifier. Last week in California in the Swinging Skirts, she led after the second and third rounds, but fell a stroke short of a playoff that Lydia Ko won over Morgan Pressel.
The top-ranked Ko rallied Friday to push her career-long cuts streak to 51, following her opening 75 with a 68 to make it on the number at 1-over 143. The 18-year-old New Zealander was tied for 62nd.
Park had a 66, and Inkster shot 69.
Lexi Thompson, Mi Hyang Lee, Hee Young Park and Karine Icher were tied for fourth at 6 under.
Michelle Wie was four strokes back at 4 under after a 70. She was 7 under through 12 holes, but bogeyed three of the last four holes.
