But the 28-year-old Smith managed to hold on to claim his fourth PGA Tour win, and afterwards, called the challenge of holding off Rahm “intense.”
“I just played really solid the whole week. Obviously, being a leader is not easy. Restless sleeps. I feel like I spent a lot of time looking at the ceiling in bed this week. I haven’t done that before. It was nice to kind of see where my game’s at against some of the best players in the world. I’ve been working hard and it’s paid off early in the season.”
Smith recorded eight birdies during his final round, including four in his last six holes.
In finishing on 34-under, Smith broke the record previously held by Ernie Els, who had shot a 31-under total at the Tournament of Champions in 2003.
The victory — in which he led from start to finish — shoots Smith to 10th in the world rankings and he becomes the fourth Australian to win the tournament.
“I’ll have to sleep on that one, to be honest. I mean, I’m quite content with where I’m at. I know mum’s car’s probably getting four or five years old, so maybe a new car for mum.”
