Collin Morikawa is back inside the top 5 in the world rankings.

The 25-year-old Morikawa moved up two spots to fourth in the latest Official World Golf Ranking after winning the WGC-Workday Championship, his fourth career PGA Tour win, on Sunday at The Concession Golf Club. Morikawa, who sits behind only Justin Thomas, Jon Rahm and world No. 1 Dustin Johnson, has previously been No. 4 in the world on a few occasions, including most recently after his T-7 showing at the Sony Open earlier this year.

Speaking with the media after Sunday’s triumph, Morikawa said he had to “reset” before November’s Masters, which capped a fall stretch that included missed cuts at the U.S. Open and Shriners Open and no top-10s in five starts.

“It wasn't like, ‘Oh, man, I should be winning every single week,’ but it just almost in that kind of fall portion, it was like, ‘Oh, I should be playing good golf, or on my bad days I should still be contending,’” Morikawa said. “When I sat down after my last event on the Tour, which was the Masters … I sat down with Rick, my coach, and I told him the honest truth, that I got complacent. I was getting lazy. I was getting a sense of where I didn't want to just be the best every single week. And that doesn't mean I wasn't practicing right … it was just a mental state of coming out and being ready to play great golf Thursday through Sunday.

“So, I kind of reset that before the Masters, I was able to work on that throughout December, a couple times on the European Tour. By the time this year started, my game felt really, really good.”

Morikawa now has three top-7s, including a victory, in four Tour starts this year.

With Morikawa’s rise, Xander Schauffele and Tyrrell Hatton each dropped a spot, to Nos. 5 and 6, respectively. Patrick Reed also moved up two spots, to No. 9, knocking Bryson DeChambeau outside of the top 10. DeChambeau, now No. 11, tied for 22^nd at Concession after missing the Genesis Invitational cut.
