- Lydia Ko wins Evian Championship
- Final round of 63 clinches title
- Youngest winner of women's major
- Lexi Thompson finishes second
Ko finished on 16-under-par 268 -- six shots clear of American Lexi Thompson with China's Feng Shanshan in third place -- a further two strokes adrift.
It was a dominant display from Ko, who aged 18 years and 142 days, takes the record from American Morgan Pressel, who was 171 days older when winning the Kraft Nabisco back in 2007.
Pressel had started the final round tied with Ko on eight under -- two shots adrift of overnight leader Mi-Hyang Lee -- but slumped to a final round 75 as her old record was broken.
"I can leave my name a little bit in the golf history books," said Ko after sealing her victory.
