Brittany Lincicome produced one of the putts of the day to card an eagle on the ninth to finish in a four way tie for sixth two shots off the pace at five under.

So Yeon Ryu, the Toledo Classic winner last week, was judging the greens nicely as she drained a length putt on the 11th to finish alongside Lincicome , Alison Walshe and Jee Young Lee after shooting rounds of 67.

Top-ranked Yani Tseng carded a two under 70 as the Taiwanese player had an up and down round but her tee shot here at the 16th was a highlight leading to one of her four birdies.

Cristie Kerr, Inbee Park and Pornanong Phatlum were a stroke behind the leaders at 6-under par after their opening rounds.

The leaders Japan's Mika Miyazato and America's Sydnee Michaels each had eight birdies and a bogey during their rounds of 65.
