Tied for the lead overnight with England's Justin Rose in the PGA Tour's final play-off event, Snedeker birdied three of the last six holes on Sunday to clinch his fourth title on the US circuit and his second of the year.

Snedeker, one of five players who came into this week knowing victory would automatically secure him the play-off crown, signed off with a two-under-par 68 at East Lake Golf Club for a 10-under total.

After chipping in from just off the green at the 17th for his fifth birdie of the day, the 31-year-old could afford the luxury of a bogey at the tricky par-three 18th, where his tee shot sailed long into a grandstand.

Rose, playing with Snedeker in the final pairing, finished alone in second after closing with a 71.

Moore, who had surged into a tie for the lead with three holes to play, bogeyed 16, 17 and the last for a 70 to tie for third at six under with England's Luke Donald (67).

World No1 Rory McIlroy and second-ranked Tiger Woods, who, like Snedeker, had victory in their sights to complete the FedEx Cup "double", finished poorly.

Northern Irishman McIlroy, winner of the two previous play-off events, hit only two of 14 fairways on the way to a 74 and a share of 10th place.

Woods, who has twice landed FedEx Cup honours, closed with a 72 to finish joint eighth at two under.
