American Billy Horschel backed up his win at the BMW Championship last week by recording a three-shot victory in the Tour Championship in Atlanta on Sunday.
Horschel shared the lead with Rory McIlroy going into the final round of the tournament, but the 27-year-old pulled away from the world number one and rest of the chasing pack on day four.
The American shot a two-under par round of 68 to finish on 11-under for the tournament to claim his victory at East Lake, and the £7m cash prize which comes with his FedEx Cup triumph.
McIlroy finished in a tie for second place with Jim Furyk, as the Northern Irishman posted a one-over round of 71 to finish on eight-under.
Chris Kirk, Jason Day and England's Justin Rose placed in tied-fourth on seven-under for the tournament.
