She managed to keep a break on her rivals throughout the round with American Auston Kim and Thailand’s Chanettee Wannasaen both shooting 68 to finish equal second on -1, three shots behind Lee. Her main challenger leading into the final round, Jeeno Thitikul, dropped away with a 75 on the final round. “I just said ‘just stick to my gameplan’. It’s a battle against myself pretty much especially with how tough the conditions were this whole week,” Lee said. “I really played within myself today.” With the $1.8million first prize in her sights, the normally composed Lee began shakily after a birdie at the first, with bogeys at the third, fifth and sixth holes, but she steadied and was on track to victory after a long par-saving putt at the 13th, and was never challenged. Her stoic demeanour never changed despite the pressure. She dropped a shot at the 16th to make the lead just three shots with two holes to play but settled with par at the par-three 17th to enjoy her walk down the final fairway. A perfect tee shot on the final hole with a seven wood allowed her to breathe easier.
