Lydia Ko became the youngest major champion in LPGA Tour history at the Evian Championship on Sunday in Evian-Les-Bains, France.

The South Korean-born New Zealander closed with an 8-under 63 for a six-stroke victory over Lexi Thompson at the final major of the season for her ninth LPGA victory.

Ko is 18 years, 4 months and 20 days old. She eclipsed the previous record set by American Morgan Pressel, who was 18 years, 10 months and nine days old when she won the 2007 Kraft Nabisco Championship.

Ko finished with a 16-under total of 268. Mi Hyang Lee, who had an overnight lead of one stroke over Thompson, crumbled under pressure and finished tied for fourth place, nine back. Shanshan Feng was third with an 8-under total of 276.

"To say that I'm the youngest in history for now, it's so cool," Ko said. "To finish with two birdies, finish on the last 72nd hole, with a birdie, it doesn't happen often, so it's definitely one of the top rounds of my whole entire life, and I'm sure it will be in my career."

Ko, Thompson and Lee were grouped together after organizers decided players would tee off on the first and 10th tees in threesomes fearing expected bad weather would play havoc with the schedule. Thompson set a tremendous early pace with four birdies in her first seven holes. She couldn't stay bogey-free on the front nine, though, missing a putt from close range on the par-3 8th.

Ko, who started two strokes off the lead, was a shot behind Thompson at the turn, with three birdies on Nos. 3, 7 and 9. Ko then hit a second shot on the par-4 11th that landed on the edge of the green and rolled to within 10 feet of the cup. Her next shot — a gutsy downhill birdie putt — went in and tied Thompson at 12 under.
