The Canadian followed up her 6-and-5 win with a 5-and-4 domination on Day 2 in Las Vegas, while Rockland's Khang lost but still has a shot to advance out of the group stage.

Brooke Henderson needed only 27 holes to win two matches. The Canadian needs to win one more to be assured of reaching the weekend at the T-Mobile Match Play.

Brooke Henderson won first two matches in routs and then advanced when her third-round round opponent, Jin Young Ko, conceded after nine holes. Henderson, who was 2-up at the time, said Ko did not feel well.
