Dustin delivers his dream

Johnson vaults to world No 1 while playing on 'cruise control'

Dustin Johnson's raw talent and a trophy case that keeps expanding allowed him to dream of being the best player in golf.

Now he can say it - even if he doesn't understand the math involved with being No 1.

With his five-shot victory at the Genesis Open on Sunday, Johnson extended a remarkable run that began with his first major at the US Open last summer, elevating the 32-year-old American to No 1 in the world for the first time.

Johnson doesn't spend a lot of time crunching numbers, especially the computations for the world rankings. But he said he would look at it first thing in the morning.

"I don't really understand it," he said. "But I can read 1-2-3. I guess that's all that matters."

In a 36-hole Sunday brought on by weather delays at Riviera, all it took was five holes to put Johnson in charge.

He finished the third round in the morning with three straight birdies for a 7-under 64 to build a five-shot lead. He started the final round with two straight birdies and eventually stretched his lead to nine shots.

He went 49 straight holes without a bogey.

Johnson didn't know he was in range of the 72-hole scoring record at Riviera that dates to 1985, the longest standing on the PGA Tour schedule.

He wasn't thinking about reaching No 1 in the world. All he cared about was winning at Riviera, one of his favorite courses.

"Winning the tournament ... that's what I was here to do," he said.

Johnson, who made three meaningless bogeys over the last 10 holes for an even-par 71, became the 20th player to reach No 1 since the world rankings began in 1986. He ended Jason Day's 47-week stay at the top.

"He deserves it because he's been playing great golf," Day said.

Johnson won for the fourth time in the past eight months against some of golf's strongest fields - the US Open at Oakmont, a World Golf Championship at Firestone, a FedEx Cup playoff event at Crooked Stick and the best field so far this year at Riviera.

He has finished no worse than third in eight of his past 16 tournaments.

"No surprise to us players, and I don't think too much surprise to many others," said former No 1 Jordan Spieth.

And it's not a surprise to Johnson.

Asked if he ever looked at himself as the best in the world even without the No 1 ranking, Johnson smiled and said, "All the time."

"I mean, I think I'm a good player. Everybody has their own opinion," he added.

"I believe in myself. I think I'm a great player. The best in the world? I mean, until now I probably wouldn't have said I was the best in the world. But now I can say it."

He heard it, too, as the gallery on the hill surrounding the 18th green began chanting, "No 1! No 1!"

Johnson finished at 17-under 267. Lanny Wadkins won at Riviera in 1985 at 20-under 264.

Johnson said he didn't know what the record was, and once he made the turn with a seven-shot lead, he started playing away from trouble to the middle of the greens.

"I didn't finish the last 10 holes the way I'd like to, but I had a pretty good lead. I was on cruise control," Johnson said.

Thomas Pieters of Belgium and Scott Brown tied for second.

No one had a chance to win as soon as Johnson began the final round with two straight birdies, but Pieters closed with a 63 and Brown shot a 68 to share the runner-up spot at 12-under 272.

That's a big step for Pieters to earn a PGA Tour card, and it assured him a spot in the next two World Golf Championships.

Cameron Tringale, who played the final 36 holes with Johnson, was 12 under until a double bogey on the final hole dropped him to a tie for eighth.

PGA Tour rookie Wesley Bryan shot a 63 in the third round on Sunday morning and got within two shots of Johnson, but only until Johnson finished off the third round with his stretch of birdies.

Bryan shot 72 in the afternoon to tie for fourth.

Bryan went to the same high school as Johnson - Dutch Fork in South Carolina - although he played most of his golf with Johnson's younger brother. But he's seen enough of Johnson to realize this was inevitable.

"Honestly, I'm surprised it took so long for him to get to No 1 in the world," Bryan said. "He's got all the talent that you could ever want in a golfer."

Rumford takes first Super 6 championship

Brett Rumford beat Phachara Khongwatmai of Thailand 2 and 1 in the final round of match play on Sunday to claim the first World Super 6 title near where he grew up in Western Australia.

Rumford led by five strokes at 17-under 199 after 54 holes of stroke play in the experimental tournament at Lake Karrinyup Country Club in Western Australia, sanctioned by the European, Asian and Australasian tours.

Eliminations during three rounds of stroke play whittled the field down to 24 for five six-hole rounds of match play on Sunday. The top eight seeded players, led by Rumford, had a first-round bye.

Favorite Louis Oosthuizen, who had a share of second spot at 12-under going into the match play, lost to Adam Bland in the quarterfinals after hitting his tee shot into a bunker on the third shootout hole and then missing a long par putt.

Rumford beat Bland in the semifinals and then was too consistent against 17-year-old Khongwatmai.

The 39-year-old Rumford underwent surgery in 2015 to have a section of his small intestine removed after falling ill in South Africa and lost his European Tour card last year during a long winless stretch, but he has earned back full status with his first win on the tour since 2013.

"All I can say is that it has been a really, really tough week," Rumford said. "You're looking at the last six holes pretty much to win a 72-hole golf tournament, so it comes down to the nitty gritty of that same feeling of trying to win a golf tournament.

"It was a unique challenge in trying to win a championship and feeling that same emotion, tension and pressure for six holes in four straight matches."
