Final round

Sunday, September 13, 2020

Overnight leaders Brooke Henderson and Nelly Korda shared and alternated the lead for much of the final round, with neither able to stretch their lead beyond one stroke until a double-bogey on the 13th hole by Henderson was followed by a birdie on the 14th hole by Korda, which moved her to 15 under par. Mirim Lee closed to within one stroke of Korda with a chip-in for birdie on the 16th hole, her second hole-out of the day after chipping in on the 6th hole. Henderson also made a birdie on the 16th to move back to 14 under par as Lee dropped back to 13 under par with a bogey on the 17th.

On the par-5 closing hole, Lee hit her second shot over the green and, after taking a free drop from against the blue wall, proceeded to chip-in for an eagle, her third hole-out of the day, to tie Korda at 15 under par. Playing behind Lee, Korda drove into the rough and had to lay-up short of the water guarding the front of the final green. Henderson was able to go for the green and, like Lee, went over the back with her ball finishing inside the blue wall. Korda could only make par after missing the green with her approach, and Henderson, having taken a free drop, was able to get up-and-down for birdie to tie Korda and Lee and force a three-way playoff for the title.^[6][7][8]

Rose Zhang, the 2020 U.S. Women's Amateur champion, finish tied for 11th with an 8-under-par 280, taking low-amateur honors. Her 72-hole score of 280 was the lowest amateur score in the tournament's history.^[15] Her finish allowed her to reach number 1 in the World Amateur Golf Ranking.^[16]
