France — Angela Stanford ended her long wait for a first major title when her 3-under 68 was enough to win the Evian Championship by one shot Sunday after long-time leader Amy Olson made double bogey on the 18th.

At age 40, and 15 years after she was runner-up at the US Women's Open, Stanford's wild final few holes gave her a 12-under total of 272.

Olson missed a six-foot putt for bogey on the 18th to force a playoff, while Stanford waited near the green signing autographs for dozens of young spectators.

Stanford, who got the last of her five LPGA Tour titles in 2012, put her hands to her mouth on hearing she had won, and was in tears during television interviews.

Stanford earned a $577,500 check for making her 14th career top-10 finish in majors a winning one.

Olson carded a 74 to fall into a four-way tie for second place with fellow Americans Austin Ernst (68) and Mo Martin (70), and Sei Young Kim (72). Martin barely missed with a birdie chance on the 18th to face Stanford in a playoff.

After Olson was outright or joint leader all day — briefly with Stanford at 13 under with four holes to play — she three-putted to end the week with a career-best result.

The 26-year-old Olson's best finish in an LPGA event was tied for seventh in 2014.
