Jason Day has won his first WGC title by beating Victor Dubuisson at the fifth extra hole in the Match Play final at Dove Mountain in Arizona.
The Australian overcame a fightback from Frenchman Dubuisson to triumph with a birdie at the 23rd.
Meanwhile, Rickie Fowler beat Ernie Els at the 19th hole in the third-place playoff.
Day's victory earns him around £920,000 in prize money, as well as a three-year exemption on the US PGA Tour.
It is also expected to see him rise from 11th to fourth in the world rankings.
