It marked the perfect end to an incredible week for the 32-year-old after wife Paulina Gretzky announced on Instagram on Saturday that the pair were expecting their second child.
It’s definitely nice to win on a golf course that I really enjoy playing
Johnson hardly played his best stuff during a level par 71 in the final round but it was enough to see off Thomas Pieters and Scott Brown by five shots as he ended the Aussie’s run of 47 weeks at the summit of the Official World Golf Ranking.

“To finally get a win at the Genesis Open feels good because I’ve finished second here a couple times, lost in a play-off, felt like I should have won a couple other times,” said Johnson, whose record at the tournament since 2009 now reads: T10, T3, T4, 2, P2, 4, 1.
“It’s definitely nice to win on a golf course that I really enjoy playing and a golf tournament I really enjoy playing.”
And speaking about reaching world No.1, the American said: “I don’t really understand it [the formula], but I can read the 1, 2, 3. I guess that’s all that matters.”
The win was Johnson’s 13th of his career and means he has won at least once in each of his first ten seasons on the PGA Tour, a feat bettered only by Arnold Palmer, Jack Nicklaus and Tiger Woods.
