Big-hitting Bryson DeChambeau shot a one under par 71 on Sunday to win the Arnold Palmer Invitational at Bay Hill in Orlando.
DeChambeau finished at 11 under for the week and moved to No 1 in the FedExCup standings. He bogeyed his opening hole on Sunday but never made another. He struck the timely shots when he was asked to, such as splitting the fairway at the par-4 18th with a 303-yard missile while clinging to that slim lead, and converting one last tricky par putt to win.
It was the 27-year-old's eighth PGA Tour title.
England's Lee Westwood finished second one shot back, while South Africa's Christiaan Bezuidenhout was six shots behind in seventh position and Branden Grace, a winner last week in Puerto Rico, 11 behind in a tied fro 26th spot.
