Dustin Johnson is 15-million dollars richer after landing his maiden FedEx Cup title by easing to victory at the Tour Championship in Atlanta.

The former world number one ended the week at East Lake on 21-under-par, three clear of Justin Thomas and Xander Schauffele. Rory McIlroy finished tied for eighth on 11-under-par.

“It means a lot, obviously it’s a very tough trophy to win,” Johnson said at the presentation ceremony. “I’ve been close several times.

“This time I did control my own destiny, I knew what I had to do. I had a lead but I still had to go out and play well today, I had a lot of great players right behind me and they played some great golf today.

“It got pretty close at the end, I knew I was going to have to come down the stretch and hit some golf shots and I’m very proud of winning the FedEx Cup trophy.

“I’m definitely playing the best I’ve ever played. I feel everything is dialled in pretty well. I’ve got a lot of confidence in every part of my game right now. I’ve got a couple of days off and then got to get ready for the US Open.”
