It was Johnson’s sixth WGC title overall and his second win in three years at Club De Golf Chapultepec and a far more comprehensive performance than his one-shot victory in 2017.
The former World No. 1 capped a 66-66 weekend for a 21-under total to win by 5 shots from Rory McIlroy and 10 shots from the remainder of the field.
Starting the day with a four-shot lead over McIlroy, Johnson looked slightly vulnerable when the Northern Irishman trimmed his lead to two after only three holes.
But three holes later, with his first birdie of the day at the par-five sixth, the American’s lead had grown to five and an avalanche of birdies would come on the closing nine.
McIlroy put together a six-under seven-hole stretch beginning at the 11th, but it put little pressure on Johnson, who made five birdies of his own from the 10th to the 16th.
A tap-in par at the par-four 18th paved the way for a stern-faced fist pump from Johnson, who is now assured of playing privileges on the PGA Tour for the remainder of his career.

And perhaps an ever more impressive statistic is that Johnson has now produced at least one victory in 12 straight PGA Tour seasons since joining in 2008.
“All week I’ve really had control of the golf ball, I hit a lot of really good golf shots and rolled the putter pretty good,” he told a media conference after his win.
“For me, today was a big day, I knew Rory was going to be coming at me pretty good, I knew I needed to play a really good round if I wanted to win.”
“20 [wins] is nice, I definitely wanted to get to that 20 number and I would have liked to have done it a little bit quicker but I’m pleased with where I’m at.
“And to get 20 wins, obviously it’s a lifetime exemption on [the PGA Tour] so that’s a very big accomplishment and I’m very proud of myself.”
Cameron Smith lead the Australians, adding a final round of 1 under 70 to share sixth, which lifts the Queenslander to 34th in the FedEx Cup standings.
Fellow Queenslander Jake McLeod matched Smith’s final round 70 to share 45th, while it was a forgettable week for Marc Leishman (T62), New Zealander Ryan Fox (T67) and Matt Millar who finished 70th in the 72-man field.
