Germany's Martin Kaymer has won the WGC-HSBC Champions event in Shanghai by three shots from overnight leader Fredrik Jacobsen.
After a par start, the world number six carded nine birdies in his final 12 holes to take the title.
Swede Jacobsen stuck with the 26-year-old for much of the day but could not match the birdie efforts of Kaymer.
Graeme McDowell finished a further shot back in third, one clear of compatriot Rory McIlroy, who was in a tie for fourth with Masters champion Charl Schwartzel and England's Paul Casey.
The victory is Kaymer's 11th on tour.
