Aditi totalled eight-under 208 with rounds of 70, 64 and 71.
It was a highly eventful round for Aditi as she went all out. She had five birdies, three bogeys and a crippling double bogey.
At one stage it was 10-under and within a shout of a top-10 finish. But a double bogey on par-4 12th and a bogey on par-13th dampened her challenge, even though she did manage a closing birdie on 18th.
At the top So Yeon Ryu, the world's third ranked player, captured her fifth career win on the LPGA. With her victory, Ryu ascends to No. 1 in the rankings for the first time in her career.
