Hideki Matsuyama of Japan became the first Asian winner of the World Golf Championship as Britain’s Rory McIlroy finished fourth.
Matsuyama carded a six-under-par 66 in the final round in Shanghai to finish seven shots clear of Sweden’s Henrik Stenson and American Daniel Berger.
His 29 birdies at Sheshan International was three short of the PGA Tour record.
Finishing on 23 under par, his total was also just one shot off the 72-hole record score at the Chinese course.
The win lifts Matsuyama to a career-high sixth in the world rankings.
Northern Irishman McIlroy carded a 66 to finish tied with American Bill Haas in fourth and move him up one place to second in the world rankings.
Scotland’s defending champion Russell Knox fell away in the final round, shooting a two-over-par 74 to end up ninth alongside Spaniard Sergio Garcia.
Englishmen Ross Fisher, Paul Casey and Matthew Fitzpatrick all posted final rounds of under 70 to finish seventh, 12th and 16th respectively.
