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.

Lydia Ko joined Henderson as the only players who have yet to play the 15th hole in either of the two rounds. The difference is Ko lost her first match (6 and 4) before a 6-and-5 victory Thursday over Gabriela Ruffels. Everyone in Ko's group is 1-1.
