Anna Nordqvist beat unheralded American Brittany Altomare in a playoff under driving rain and hail at the first extra hole to win the Evian Championship on Sunday.
Nordqvist sank a 4-foot putt for bogey 5 on the soaked 18th hole while 102nd-ranked Altomare had a six.
Nordqvist, 30, earned $547,500 for winning her first major since the 2009 LPGA Championship.
Altomare got $340,000 for only her second career top-10 finish.
Nordqvist and Altomare both shot 66 for nine-under totals of 204. It was a 54-hole event after weather-affected play Thursday was scrapped.
Second-round leader Moriya Jutanugarn of Thailand and two-time major winner Lydia Ko of New Zealand fell out of the playoff by dropping shots on the 18th.
Nordqvist's victory ensured 10 different major winners in the last two seasons.
