May 9 (Reuters) - Former world number one Ariya Jutanugarn hit a flawless nine-under-par 63 in the final round of the Honda LPGA Thailand on Sunday to become the first local winner of the $1.6 million tournament.
The 25-year-old Thai had a nervous wait in the clubhouse before her 11th LPGA title was confirmed when a thunderstorm forced a one-hour suspension of play at the Siam Country Club with six players still on the course.
After play resumed, Thai teenager Atthaya Thitikul, who led by a shot with two holes to play as she chased her maiden LPGA title, was only able to par the 18th for a 68 to fall one stroke short of Ariya's tally of 22-under 266.
South Koreans Ryu So-yeon and three-times tournament champion Amy Yang both shot fourth round 64s to share third place with American Angel Yin (66) and overnight leader Patty Tavatanakit (70) on 20-under.
