Thailand's Ariya Jutanugarn triumphed in the CME Group Tour Championship thanks to two late birdies and a missed short putt by Lexi Thompson.
American Thompson looked set for glory at the Tiburon Golf Club in Naples, Florida with a one-shot lead going onto the 18th green.
But a missed a two-foot par putt dropped her into a three-way tie and set up Jutanugarn the chance to grab the headlines.
The 21-year-old world No 9, who started the day among the quartet holding the lead, stayed cool to sink an 18-foot birdie putt for a five-under 67 and a one-shot victory.
Thompson and compatriot Jessica Korda shared second, just one stroke adrift, with Sweden's Pernilla Lindberg and South Korean Ji Eun-Hee tied for fourth a shot further back.
Thompson needed to win to secure the LPGA Tour player of the year award. Her consolation was winning the $1m bonus for the CME Race to the Globe and the Vare Trophy for the lowest scoring average.
"It is very special," Thompson said. "It has just been an incredible week."
The points-based player of the year was a tie between So Yeon Ryu and Sung Hyun Park.
Britain's defending champion Charley Hull finished in a share of 11th.
The 21-year-old from Kettering, last year's champion when winning her maiden LPGA title, was five shots behind after a two-under 70.
