Kim closed with a 7-under 65 on Sunday for a nine-shot victory, finishing at 31-under 257 to break by four shots to par the record Kim had shared with Annika Sorenstam.
Speaking of her 63-65-64-65 tournament, surpassing Annika Sorenstam's 27-under record from 2001, she told LPGA.com: "After I shot 27-under (at the 2016 JJTBC Founders Cup), I wanted the 72-hole record". For the tournament, she never recorded a bogey, with her only blemish being a double bogey at No.17 on Friday.
Including her final round of 63 at this event past year, Kim has now played her last 72 holes at Thornberry Creek in 33 under par and her 7th LPGA Tour title now appears but a formality.
"Just before I started (the final round), I setting my goal of a bogey-free round", she said afterwards.
"I made a really good up and down on 17 and then to stick it close on 18 to give myself an opportunity was great", said Law. But after the major tournament, I realized, 'OK, I can do that.' If I imagine, it comes true.
Even with an eight shot lead entering the round, Kim never let her foot off the gas pedal.
Carlota Ciganda finished in second at 22-under while Anna Nordqvist, Emma Talley and Amy Yang tied for third at 20-under.
When defending champion Katherine Kirk opened the 2nd annual Thornberry Creek LPGA Classic with a mind blowing 10 under par 62, the question on everyone's mind was how low can these women go?
"Front nine, I just couldn't get one to drop, and back nine, hit lots of good putts and, again, nothing happened", Kirk said.
For all the birdies, Kim set the LPGA Tour record with a par on the final hole to finish at 257.
DONEGAL, Ireland (AP) - Russell Knox of Scotland holed almost identical putts of 40 feet on the 18th hole, first to get into a playoff, and then to beat Ryan Fox and win the Irish Open for his first European Tour victory.
The New Zealander took 33 putts for the round and hit only five of 14 fairways and 14 greens in regulation.
The Thornberry winner's cheque of US$300,000 pushed Kim's career earnings past US$5 million, making her the 61st player to reach that plateau in LPGA history. "It's unbelievable the way she (Sei Young) played".
Her last LPGA victory was in May 2017 when she beat Ariya Jutanugarn at the Citibanamex Lorena Ochoa Match Play.
"I had the double-bogey on 17". "I really feel incredible".
