World No 5 So Yeon Ryu is one shot back, after a storming eight-under through 17 holes, with world No 3 Stacy Lewis of the US a greater danger on the same score, as she has five holes to play.
She’s only the third player to win such a title before turning 18 and she is the first Canadian, regardless of age, to win an LPGA Tour event since Lorie Kane of Charlottetown won the Takefuji Classic in 2001 – when Henderson was a three-year-old.
Canadian teen Brooke Henderson won the LPGA Tour’s Cambia Portland Classic last Sunday, but that didn’t guarantee her the two-season exemption that comes with a victory.
