American world number two Nelly Korda was in a three-way share for fifth after carding 68. After a difficult opening day with the putter, South Korea's reigning champion Ko Jin-young shot eight birdies and a bogey to climb up to tied eighth with a seven-under 65, while top-ranked Lydia Ko (69) was in a share of 16th.
