CHONBURI, Thailand — Stacy Lewis shot a 3-under 69 Friday to keep her three-stroke lead after the second round of the LPGA Thailand.

Lewis had five birdies and two bogeys to follow up her 63 Thursday for a 12-under 132 total at the Siam Country Club Pattaya Old Course, replicating her 2012 form that made her the first American to win the LPGA Player of the Year award since Beth Daniel in 1994.

Thai teenager Ariya Jutanugarn shot a bogey-free 66 in windy and humid conditions to move into second place.
