He gave his challengers a glimmer of hope when he dropped a shot at the short 11th hole when his tee shot found the bunker, but recovered strongly at the next, nearly holing his tee shot at the 433-yard par four 12th hole.
Johnson ended up taking out the Kapula Resort PGA contest by eight shots, pocketing a cool $6,300,000 United States dollars for his efforts. Seconds earlier, on-course reporter Jim "Bones" Mackay was saying that with the wind, Johnson might have too much power for the hole and could overshoot the green.
The way he played the Plantation Course, it was hard to tell.
Well, the PGA Tour's Twitter account on Monday posted a video of a number of near-hits that other players - from the legendary Nick Taylor to two-time major champion Zach Johnson - have enjoyed over the past several years. "If I keep playing good, keep working, keep learning about myself, I just need to keep getting better scores without my A game like I have this week", Rahm said of trying to push even higher. He had a pair of double bogeys over the last four holes, sandwiched between birdies, shot 75 and was 18 shots behind.
He did most of his damage on the three-hole stretch on the back nine where birdies are available.
"So I knew it was going to be pretty good I just didn't think I was going to have a tap-in".More news: Two injured after fire at Trump Tower in NY
Spain's Jon Rahm was second after a 69 for 276 and is set to rise from No. 4 to No. 3 in the world.
Halfway leader Marc Leishman recovered from his disappointing third-round 76 with a 67 to tie for seventh place alongside Colombia's Jhonattan Vegas on 13 under, while Open champion Jordan Spieth was one shot further back on 12 under after carding a 69. Johnson went low on Saturday with a blistering 66.
"After China where I didn't...where I struggled a little bit on Sunday, I didn't want that to happen again", Johnson said with a wry smile.
"But everything's going in the right direction".
