Genesis Open champion and new world number one Dustin Johnson poses after winning the trophy.

Dustin Johnson likes the sound of being world number one after dethroning Jason Day on Sunday as the U.S. Open champion said he always believed in himself.

Johnson grabbed golf's top ranking after winning the Genesis Open by five strokes at 17 under at Riviera Country Club.

It was a tireless day for Johnson, who played 36 holes due to weather interruptions, as the American closed out the PGA Tour tournament with a final-round 71, having carded a seven-under-par 64 earlier in the day.

And Johnson revelled in his achievements after adding a 13th Tour title to his collection to leapfrog Australian Day, who finished two over the card.

"It sounds good [world number one]. It was a long day but I played really great all day," Johnson told reporters. "I really drove it well, had that new M1 driver and I couldn't have driven it any better. That was a big key for me today.

"It gives me a lot of confidence, it's going to push me to work even harder, try to get even better.

"I didn't finish the last 10 holes the way I would have liked to do. But I had a pretty big lead there with 10 holes to go, so I was kind of on cruise control. I still would have liked to play a little better the last 10 holes."

Asked what meant more to him - winning the tournament or becoming the new number one - Johnson replied: "Winning the golf tournament is most important right now. That's what I was here to do.

"I wasn't really thinking about my world ranking. I was thinking about winning this golf tournament."

As for his self-belief, Johnson said: "I think I'm a good player. But everybody has their own opinion. I believe in myself. I think I'm a great player. Before, I wouldn't have thought I was the best player in the world, but now I can say it."

Winning the Genesis Open - formerly known as the Northern Trust Open - had been a long time coming for Johnson. The 32-year-old was a two-time runner-up at Riviera without success, until Sunday.

"Feels good. I finished second here a couple of times, lost in a play-off," he said. "Came close some other times. It finally feels nice to win on a golf course I really enjoy playing."
