LPGA: Thai women shine at home
Three local golfers starred in the first round of the Honda LPGA Championship in Chonburi, Thailand, and sat at the top of the standings.
Thai Patti Tavatanakit and Athaya Thetikul led, both with 64 points (-8). Tavatanakit made no fewer than nine birds and made an insect. For his part, Theicool equipped two eagles and five birds, and registered a ghost.
For her part, Ariya Jutanugarn finished third, along with Danish Nanna Koerstz Madsen, after wrapping up the inaugural round with a score of 65 (-7). It came very close to catching up with its fellow countrymen in the lead, but a mistake in the 18th Banner prevented it from doing so.
New Zealander Lydia Coe, German Caroline Mason and Australian Hannah Green came in fifth after two shots from the header.
Lone Canadian Alina Sharp cut the par to finish with a 71 (-1) card. Ontario had six birds, but its three chariots and double wagons in the eighth hole laid them down. She is 33, seven hits behind the leaders.
