The victory would be even more special for Lee as it came on her 22nd birthday and atones for a playoff loss to Lydia Ko a few weeks ago and her runner-up finish in this same event last year.
Beginning the day with a two-shot lead, Lee moved three clear in the middle stages of her round and looked to be in complete control until a final nine charge by Kim and a three-putt bogey by the Australian at the 17th had the pair tied for the lead as Lee stood on the 18th tee.
Lee would miss the green right at the with a five iron at the reachable par 5 but a fine pitch and run to four feet under pressure set up the birdie putt and the win.
The victory was worth US$195,000 to Lee and takes her earnings for the season to $628,726, to 4th on the money list and to 4th on the CME Globe table.
For Lee the victory could not come at a better time ahead of the second major of the year for women’s golf, the US Women’s Open in Alabama this week but Lee would say that this week has little bearing on next week.
Never one to give much away in interviews Lee played down the significance ahead of next week’s demanding test at Shoal Creek.
“Not really,” Lee responded when asked by on course commentator Gerry Foltz how this win will assist next week. “Next week is going to be a totally different week. I know I am hitting it pretty solid and putting solid so hopefully I will have a great week."
Lee held off not only I.K Kim but also bold challenges from Moriya Jutanugarn and a four-month pregnant Stacy Lewis, Lewis blundering over the final stages with a double bogey and bogey at her final two holes.
Moriya Jutanugarn would finish alone in 3rd place while Australia’s Su Oh produced her best LPGA Tour finish in nearly 12 months and reversed what has been to date a very ordinary season in 2018 when she tied for 5th with American Lindy Duncan.
Of the other Australians aside from Lee and Oh, Sarah Jane Smith was 32nd and Hannah Green 63rd.
Now it's on to Shoal Creek in Alabama for the women's game's greatest event: the US$5 million US Women's Open.
