"It was windy today," Henderson said. "I feel like overall Britt (caddie and sister) and I did a really good job again just calculating numbers and negotiating the wind as best we could. There was a couple of bogeys I would like to take back, but having four birdies is really good."
Feng had nine holes left when play was suspended because of darkness. On her last hole, the Chinese star birdied the 18th.
"I know this is only the first tournament of the year, but normally I'm pretty good in the wind," Feng said. "Actually, I get more excited in the wind. It's not really bothering me."
Henderson began the second round with a bogey Friday morning just before play was called for the day. The 20-year-old Canadian dropped another stroke on the par-3 third, birdied the par-4 sixth and played the back nine in 1 under with birdies on the three par 5s.
"I'm try to hit as many low shots as possible, not just into the wind, but also when it's across and sometimes even down," Henderson said. "And just play in the back of my stance, keep my hands low."
Lexi Thompson was 3 under along with Ryann O'Toole, Danielle Kang, Luna Sobron Galmes and Wei-Ling Hsu. Thompson and Sobron Galmes had 10 holes to play in the second round, and Hsu had nine left. O'Toole had a 69, and Kang shot 73.
Brittany Lincicome, the winner last year in a playoff over Thompson, was 2 under with nine holes left. Michelle Wie was even par for the week with nine holes to go.
