Jason Day will be grouped with his friend Tiger Woods in the first two rounds of the Farmers Insurance Open at Torrey Pines this week.
The Australian tees off at 5.40am (Australian eastern time) Friday with Woods and Dustin Johnson as he continues his return from the back injury that kept him from playing the last few months of 2016.
Day finished tied-12th in the SBS Tournament of Champions in Hawaii earlier this month in his first tournament since resuming.
"I came off three months without touching a club, practically," he told media today at Torrey Pines. ""I've had a lot of good prep; eight straight days of just hard work and the gym. I feel mentally and physically ready to go; the touch is coming back – worked out some of the kinks in the putting overall."
Day, who is still ranked No. 1 in the world, remains mindful of the disc problem in his back, although he has had no major issues with it so far this year.
"I was talking to Tiger about it the other day; I want to win and be successful, but at 40 I don't want to be walking around with a cane," Day said.
"There's nothing like having your health. But once again, if I keep going the way I'm going, I don't even know if I'll make it to 40."
