Lewis leads in Thailand
Stacy Lewis could not match her fine form from the first round but still led by three shots after the second round of the Honda LPGA Thailand.
Two bogeys slowed Lewis in a round of 69, three under par, and six shots worse than her first round as she moved to 12 under.
Even so, Lewis retained a healthy advantage as her closest challengers overnight suffered a dismal day.
France's Karine Icher, who had been three behind, had six bogeys and one double bogey in a round of 77 that saw her tumble to a share of 25th place.
Of the players who had been tied for third on five under, only Scotland's Catriona Matthew shot anything under 70 today, with her 69 keeping her in a share of third.
Ariya Jutanugarn is now Lewis' closest challenger after a round of 66 - the best of the day - moved her to nine under, while So Yeon Ryu and Beatriz Recari both went round in 68 to join Matthew on eight under.
