ÉVIAN-LES-BAINS, France — With two holes left to play at the Evian Championship on Sunday, Lydia Ko stayed as relaxed and composed as a seasoned veteran. Ko, a South Korea-born New Zealander, birdied both holes on the shores of Lake Geneva to reach a new landmark in her short but already storied career.
With a flawless final-round display that featured spectacular approaches and clinical putts among her eight birdies, Ko became the youngest major champion in L.P.G.A. Tour history. She closed with an eight-under-par 63 for a six-stroke victory over Lexi Thompson at the final major of the season.
