Ted Potter Jr. outplayed the world's No. 1 player and held off everyone else to win the AT&T Pebble Beach National for his first victory since a broken ankle almost ended his career.
World number one Johnson fired an eagle and four birdies in his two-under par 70 at Pebble Beach Golf Links, one of three tournaments in use for the first three rounds of the PGA Tour event.
After flirting with a 59 on Saturday, Potter got off to another hot start in the fourth round, birdieing four of his first seven holes.
It's the second victory of his career, the first coming almost six years ago at the 2012 Greenbrier Classic. The Florida native closed it out in veteran fashion, making 11 straight pars to hold off the likes of Johnson, Jason Day and Phil Mickelson.
"It's great but I'm just hoping moving forward we don't have to talk about color anymore", Fitzgerald said.
Winter Olympics: NBC Apologizes For Analyst's Remarks on Korea
NBC issued an apology for Ramo's comment before later announcing his assignment at the Olympics is now over. His incorrect and insensitive comment about Korea's history has enraged many of its people.
"Just back from my mini-tour days, tournaments I've won in the past, just drawing back from past experience of winning golf tournaments", he said. "Going back to the Masters, it'll definitely be another dream come true". "I get my second career win after five years away from it".
Johnson started the day tied for the lead, but he floundered Sunday.
"I felt like I played OK", Johnson said. The Australian has not finished outside the top 25 since the 2017 Open Championship.
American Kevin Streelman (68) finished alone in sixth and Scott Stallings (66) was seventh at 12-under 275, five shots adrift of Potter. The 36-year-old improves to 9-for-9 on the season with a TOUR-leading eight top 25s and posts his second top 10 and second straight after P2 last week in Scottsdale.
