Jordan Spieth believes his victory at the Dean and DeLuca Invitational can prove a turning point in his season ahead of a busy summer.

After leading overnight, the 22-year-old reached the turn at level par for his round but then found his touch, with six birdies on the back nine and just a single dropped shot to finish with a 65.

His tally of 17-under was enough to give him a three-stroke win over Harris English, while Ryan Palmer and Webb Simpson tied for third on -13.

Spieth’s maiden win in his home state of Texas was his first since collapsing on the back nine at last month’s Masters and will help rebuild his confidence ahead of his US Open defence in June.

The world number two is currently the 7.50 joint favourite to win at Oakmont, with both Jason Day and Rory McIlory tied alongside him at the same price.

His victory at Colonial will certainly come as a timely boost and Spieth admits his success on Sunday could prove hugely significant.

“I am already looking back thinking that this will be a very important day that I’ll never forget, to get back on top and be in the winner’s circle,” he said.

“As a golfer, as a person, I can always look back on this experience and say we were strong through tough times just given the position we’re in, and that creates noise.

“It’s great when you’re on top, and it’s not fun on the other side of it, but it makes me really enjoy a moment like this even more. It really does.”
