Scott has also improved his Fedex Cup standing from 21st to 14th as the series heads to Chicago for next week’s BMW Championship.
Scott had won at Liberty National previously when successful in this event’s equivalent in 2013 and again displayed his liking for the layout with four rounds in the 60’s including his round of 6 under today.
Scott heads to the BMW Championship with his game in great shape with the chance to stake his claim for even higher honours in the FedEx Cup.
"I hit the ball well today. Much better than the first three days," said Scott.
I worked on a couple things in the warm-up today and that worked out nicely. It was a good day to hit it well because the greens, the pins were a little tougher, and you didn't want to have to be scrambling too much.
"I kind of took advantage of most of the good shots, but a couple on 14 and 15 that I might regret missing, but all in all, it was really good, and now I'm going to go into next week kind of knowing that I'm probably at East Lake and have a crack next week."
Scott finished as the leading Australian by some margin this week, Matt Jones the next best when he finished 30th and Cameron Smith 59th.
Scott, along Jason Day and Marc Leishman, who both missed the cut this week, are the only three Australians who get to play the BMW Championship, Smith dropping to 84th and Jones 91st in the standings with only the top 70 heading to Chicago.
