Fresh off his best tournament result in almost two years, Jason Day feels ready to turn around his poor run of results at Los Angeles' Riviera Country Club.
Day finished near the bottom of the field in all four previous appearances but ends a three-year absence this week now the US PGA Tour has rebranded the tournament as Tiger Woods' invitational tournament.
The former world No.1 is coming off a fourth placing at the Pebble Beach Pro-Am on Sunday, his best result worldwide since winning the Wells Fargo Championship in May 2018.
That lifted him to No.35 in the world rankings and ensured he avoided dropping out of the top 50 for the first time since he broke into it 10 years ago.
The 12-time US Tour winner says his confidence has returned.
"Coming off a good finish last week is nice because I'm feeling good about my game and I'll need that this week at a demanding course like Riviera," Day told AAP.
"I think overall, I'm most excited about the way I'm striking the ball and the way I'm putting."
Day missed the cut in his first two appearances at Riviera.
The difficult course near Santa Monica is known for demanding iron shots and quick and bumpy Poa Annua greens.
It is why Day, who owns one of the best short games in golf, has been practising his chipping and pitching even more in the lead up.
"You have to have great touch around the greens here because there are some really tough shots if you miss the green," Day said.
"I know I haven't had greatest results here but I'm ready to turn that around."
Day said part of the reason for returning to Riviera for the first time since 2017 was because the Genesis Invitational has been elevated to the same prestige as tournaments hosted by golf greats Jack Nicklaus (Ohio) and the late Arnold Palmer (Florida).
The Genesis Invitational will now offer the winner a three-year exemption on the PGA Tour, one more than regular events, and a $US1.674 million ($A2.49m) winner's prize.
"I think it's only right for Tiger to have his own event; it's good for the game of golf to reward him for his legacy in the sport," Day said of 15-time major winner Woods.
"It's great to be here in LA because he grew up around here and began his career at Riviera."
Nine of the world's top 10 golfers will tee up this week.
Australians in the field are Day, former winners Adam Scott and Aaron Baddeley, as well as Marc Leishman, Cameron Smith and Matt Jones.
