Jordan Spieth capped an unforgettable season in fitting style with victory in the Tour Championship to secure the FedEx Cup title and a massive payday in Atlanta.
Spieth carded a 69 at East Lake to finish nine under par, four shots clear of Henrik Stenson, Justin Rose and Danny Lee.
The first prize of £977,000 and bonus of £6.5 million took Spieth’s earnings for the season to more than £14 million, and with Jason Day finishing joint 10th, it also took the 22-year-old above the Australian and Rory McIlroy to the top of the world rankings.
England’s Justin Rose was within two of the lead when his fourth birdie of the day took him out in 31, but hooked his tee shot out of bounds on the 10th.
Rose finished with a 66 for a total of five under, alongside Danny Lee.
Masters and US Open champion Spieth took a one-shot lead over Henrik Stenson into the final round.
He three-putted for a bogey on the sixth, but quickly regained his composure and holed from 20 feet on the eighth.
It looked as though Stenson would cut the gap to a shot after leaving himself a tap-in for birdie on the par-five ninth, only for Spieth to hole from 18 feet.
The Swede paid for a shank on the 17th, costing him a double bogey, and could only manage a 72 to finish tied for second with Rose and Lee.
Paul Casey suffered a bogey on the 16th after birdies on the previous three holes had moved him into joint second.
His final round of 70 left him tied at four under with Dustin Johnson, who shot a fine 64, and Bubba Watson.
Meanwhile, Rory McIlroy came to grief with a triple bogey seven on the 17th, finishing tied 16th.
