The 20-year-old had a topsy turvy day, adding four birdies but also three bogeys and a nasty double-bogey at the short 16th following a four-putt, which significantly impacted her lead.
"Watching Pernilla Lindberg win her first major two weeks ago now, it was actually a lot of motivation and it really inspired me", Henderson described.
Henderson gave herself several chances to run away from the rest of the field at a windy Ko Olina Golf Club on Friday, but in the end had to be content with a one-over-par 73 that nevertheless saw her retain her position at the top of the leaderboard. Sixteen people died when a bus carrying the Humboldt Broncos, a junior team in the Saskatchewan league, crashed last week when a tractor trailer collided with it. Henderson played her rounds with green and yellow ribbon in her hair, the teams colors. "I wake up and I'm like, 'Yeah, it's windy.' That's why in this kind of situation I still stay patient on the course and still stay with my routine". Everybody really took it kind of personally.
Spain's Azahara Munoz had a 67, the low round of the day, to finish second while top-ranked Shanshan Feng (71), third-ranked Inbee Park (72) and sixth-ranked Ariya Jutanugarn (69) tied for third at seven under.

"Mentally I was in a great spot this week", Henderson said. She was two shots back after her fifth birdie of the day, at the 14th, but parred in.
Taiwan's Peiyung Chien (final-round 2 under) and Americans Lindy Duncan (2 under) and Lizette Salas (even) shared sixth place at 6 under par. Defending champion Cristie Kerr also shot 73 and was another shot back.
