Nordqvist had three birdies and three bogeys in the second round and is at 6-under 138 halfway through the tournament.
In the race for the world No. 1 ranking in women's golf, top-ranked Inbee Park shot a second consecutive 71 and is tied for 11th at 2-under with six other players, including No. 2-ranked Suzann Pettersen who was 1-over in the second round. Park is the Honda LPGA defending champion.
Nordqvist opened her second round with eight pars but pulled away from the field with birdies at Nos. 9 and 10. She gave back a stroke at the 11th hole but returned to 2-under with a 12th-hole birdie for a three-stroke advantage.
But she had bogeys at 16 and the par-5 18th that tightened the leaderboard going into the weekend.
