What it means: This is Park's sixth major victory and her fifth in the last three seasons. She is just the second woman to win the same LPGA major three years in a row, joining Annika Sorenstam who also did it at the Women's PGA (then-LPGA Championship) from 2003-05. Park made five birdies in a bogey-free round, played her last 57 holes on the West Course without a dropped shot and tied the tournament scoring record in relation to par. With the win, Park also takes back the Rolex No. 1 ranking from Lydia Ko, to whom she forfeited the top spot in February. With Ko missing the cut earlier this week, Park needed only a finish of 29th or better to pass the 18-year-old. This is the third time Park has ascended to No. 1 in the world.
Round of the day: Lexi Thompson and Sandra Gal turned in rounds of 7-under 66 to tie for the low round of the week. Thompson was actually 8 under through 15 holes before a bogey at 16 proved her only dropped shot of the day. Gal, somewhat incredibly, finished both the round and the tournament 7 under after opening rounds 70-74-75. She, too, made just a single bogey Sunday.
Best of the rest: Henderson did not charge from six back to become the youngest winner in major championship history, but she did help her chances of securing LPGA membership next season. The 17-year-old shot 71 to finish in a tie for fifth in just her third major start. Henderson is trying to earn LPGA membership through top-40 money equivalency and came into this week 33rd. A top-five finish in a major will help her cause as she may only be eligible for three more LPGA starts this year. Separately, Lincicome followed up her ANA win with a solo fourth. She's finished in the top eight in each of the last four majors, going 2-8-1-4.
Biggest disappointment: Runner-up Sei Young Kim posted a final-round 71 but proved unable to pressure Park thanks in part to a double bogey on the par-5 ninth. After reaching the green in four, Kim three-putted from roughly 4 feet, running her first try past hole the and lipping out her comeback attempt. Nevertheless, the LPGA rookie earned her highest finish in a major and her second top-five in four tries after a T-4 at the ANA Inspiration earlier this year.
Shot of the day: Hyo Joo Kim made an ace at the par-3 14th en route to a closing 71 and a T-9.
