Indeed, Rose carded bogeys on three of his first five holes Sunday and saw his lead evaporate to a mere shot.
His three-shot lead was down to one through six holes of the Farmers Insurance Open, and the biggest battle was trying not to panic.
But the birdie on the sixth hole would prove to be Rahm's last.
Rose began rebuilding his lead with birdies on the seventh, ninth and 10th holes.
Quiros had an ugly end to his round, making double-bogey at the par-5 last after finding the water surrounding the green off his second shot, hitting his fourth shot into thick rough at the back of the green, and then duffing his chip.
Rose birdied the par-five 13th and rolled in a 24-footer for birdie at 16 to pad his lead.
"I can't believe how well I've driven the ball this week on a tough test".
"Man, I'm just not 100 percent with my golf game right now", DeChambeau said after his 4-under 68 in the third round Saturday, which gave him a one-shot lead over defending champion Li Haotong of China.
"He's the No. 1 player in the world and he's showing why right now, " said Scott, whose 19-under-par effort would have won the past nine Farmers tournaments. Rose dedicated the victory to his caddie, Mark Fulcher, who had a heart procedure last week and was watching from home. Nick Faldo had nine from 1984 to 1997.
But new world No.30 Scott downplayed his accolade, given the vast increase in PGA Tour purses in the Tiger Woods era.
Pelicans star Anthony Davis wants out of New Orleans, requests trade
According to Chris Haynes of Yahoo Sports , the Lakers, as expected are going to be one of those interested teams. In that time , the Pelicans have only made the playoffs twice, and have advanced past the first round once.
The Englishman dedicated his victory to his regular caddie, Mark Fulcher, who underwent heart surgery on January 17 in New York City. Rose used Gareth Lord, who previously caddied for Henrik Stenson and knows Rose well from Ryder Cup partnerships. "This one's for him".
It might have gone the other way after Rose lost the 2017 Masters in a playoff to Sergio Garcia.
"Anything before that would be a bonus", Rose said. I'm feeling good and my body's feeling really good. "He never really was under much pressure". "I was a little bit sharper each and every day".
Japan's Hideki Matsuyama (67) and American Talor Gooch (68) tied for third, five strokes behind Rose.
"Well it was nice to shake off some rust", the 14-time major victor said. "By the time I got it sorted out, it was a bit too late".
"This week wasn't as good as I would like to have it". Today, I tried to at that point. "I feel like I played solid in the final round and that's what you need going down the back nine". I struggled on my own, I brought Joey in, we struggled together. "Everything has worked out better than I would have hoped, for sure, the first couple weeks".
Woods will next play in the Genesis Open, which begins February 14 at The Riviera Country Club in Pacific Palisades. "He's a grinder", said Rory McIlroy of Rose. "People, rightfully so, they don't understand why I would make that change, but I made the change hopefully to get better as a golfer. It's hard to beat that when you're three [shots] back around this course".
Rose also received a trophy and a surfboard for the victory. "Twenty-one under around Torrey Pines is great golf", Rose said. "It's going to look fun somewhere in the house".
