Brooke Henderson shoots final round 67, ties for 4th in Thailand

Nanna Koerstz Madsen became the first Danish player to win an LPGA Tour title after a dramatic second-hole playoff victory over Lin Xiyu of China at the Honda LPGA Thailand on Sunday.

Both players set a new tournament record of 26-under-par 262 in regulation, and then birdied the par-5 18th in the first extra hole before the Dane sealed the win with a 7-foot eagle putt in the next to secure her biggest career victory.

"It's amazing. I don't know how to put it into words," said Madsen from Chonburi. "It's something I've dreamed of for a very long time."

Celine Boutier of France finished a shot behind the leaders in third after a final-round 67. Three-time champion Amy Yang (64) of South Korea and Canadian Brooke Henderson (67) finished another two shots back.

The 27-year-old Madsen, who shot a final-round 5-under 67, also became the third European to win the event after Suzann Pettersen of Norway in 2007 and Anna Nordqvist of Sweden in 2014.

Madsen had started her final round at the Siam Country Club Old Course at Pattaya the way she ended her third. Even better, on the way to her first LPGA Tour victory.

And she needed every one of those early breaks to put herself in a position to secure the win.

After making birdie on her final two holes in the third round to take a one stroke lead into Sunday, the two-time Olympian from Denmark eagled her first hole and birdied the second to increase her lead. After a bogey on the seventh, she came back with birdies on the eighth and ninth for a three-stroke lead at the turn.

Then, after rain suspended play for two-and-a-half hours, the Dane blew a four-stroke lead with three holes to go.

Madsen still had a two-shot
