Heavy rain and a series of delays could not stand in the way of South Korean Amy Yang coasting to a five-stroke, record-breaking win on a marathon final day at the Honda LPGA Thailand.
The 27-year-old was forced to play the final 23 holes on Sunday after bad weather struck the Siam Country Club's Pattaya Old Course earlier during the tournament, but she wasn’t troubled in securing victory on the back of a closing round 68.
The round saw her reach 22 under and set a new tournament record, one shot better than 2007 winner Suzann Pettersen and 2010 champion Ai Miyazato.
Yang, the 2015 champion, led by five strokes heading into the final round, having added a single birdie in her last five holes of the third round.
She saw her lead reduced to just three shots several times during the final round but birdies at the par-4 15th and the par-5 18th pushed her winning margin to five strokes.
"I am beyond happy, I had so many early wake-up calls this week," said Yang, who had to play 31 holes on Saturday as well as the 23 on Sunday.
"I had to stay patient out there.
"I love this place, I love the people here and I always seem to play well. It's a great start to the year and I am really looking forward to the rest of the season."
It was a South Korean trifecta with So Yeon Ryu (68) finishing second on 17 under, and Sei Young Kim (68) outright third, a further two strokes back.
Of the Australians, Minjee Lee bounced back from two ordinary rounds to fire a closing three under 69 and claim a share of 25th place.
