Jon Rahm, who won last week is the defending champion this week at the Farmer's Insurance Open. Yet the focus this week when action gets underway at Torrey Pines, will be Tiger Woods.
Woods, the 14-time Major winner, is playing his first competitive event since the Hero World Challenge in the first week of December.
It will be his first PGA Tour event in a year, and this return is buoyed by his optimism about a successful back fusion surgery.
In the first round, Woods will play with Patrick Reed and Charley Hoffman.
The other big stars in the field are Rickie Fowler, Jason Day, Justin Rose, Reed, Hideki Matsuyama, and Phil Mickelson among others.
Lahiri has already played most of the golf courses on the PGA TOUR.
"It definitely helps when you're going back to a venue for the second or third time. I'm also feeling more at home with everything else, with the players and how things work," he said.
