Heading into Sunday’s final round, Sei Young Kim shared the record for lowest score to par in a LPGA event with Annika Sorenstam. After her win at the Thornberry Creek LPGA Classic has that distinction all to her self.

“When I warmup in this — not morning, afternoon — I was feel a little bit of different than the third round because a little bit of pressure. And then after that I think about the how do you handle nerves today. Maybe it’s going to be really a hard time or really good time. Yeah, and then I setting my goals just keep relax and then until last hole. Yeah, it did, and then except last three holes I couldn’t control nervous because it’s almost done,” said Sei Young Kim.

Starting the day with an eight shot lead it would likely take a collapse on Sunday for Kim not to bring home the Sky Woman Trophy. Spain’s Carlota Ciganda made a run and nearly tied the tournament single round record before a double bogey on the 18th hole. At the end of the day even carding a 62 wouldn’t help her overcome Kim.

The native of South Korea kept her foot on the gas on the front nine. Passing the four under par needed to get the record all to herself. In the end she carded a seven under 65 in the fourth round, stretching that score to -31.

“I really feel like unreal. I never thought about shot like 31-under. I was like really feel like incredible,” said Kim.

It’s Sei Young Kim’s seventh win on the LPGA tour, and her first in 31 starts.
