Bryson DeChambeau believes he can carry strong momentum into the majors this year after winning the Rocket Mortgage Classic.

DeChambeau secured a three-stroke victory at the Detroit Golf Club in Michigan on Sunday to continue his good run of form.

The American had six top-10 results heading into the Rocket Mortgage Classic and appears set to contend with three majors to be held before the year's end.

DeChambeau said he was gaining confidence and it would give him momentum ahead of the majors, where he is without a top-10 finish in his career.

"The most important thing is that I played on a golf course that required unbelievable wedging and that's not one of the strong suits of my game, and I was able to win and win by a few, so that's really positive," he said.

"It means my wedge play isn't up to the best in the world, but it's definitely good enough to still compete on Tour. My driving's still good enough to compete on Tour.

"It's really exciting to be able to get the job done here and it's a lot of momentum for the majors. I feel like it's a good test run for me hitting drives in some tight areas. Number seven wasn't easy this week and I hit great drives there all week. I've been hitting a great job at 18 when I had to, absolutely had to. If I hit it in the water or a little left or a little right, I'm struggling to make par, but I was able to give myself a little wedge shot in there.

"It gives me a lot of confidence going forward that I'm heading in the right direction with my driving and my game."

DeChambeau carded a seven-under 65 in the final round on his way to a sixth PGA Tour victory.

The 26-year-old said he was happy with the way he played as he carded the best round on Sunday.

"It's funny, I was kind of in my own world the whole day, I never really thought much about anything outside of me," DeChambeau said.

"Man, I was just focusing on my game, trying to execute every shot to the best of my ability and I did that for quite most of the day."
