Woods is on the verge of returning to the winner’s circle for the first time at a PGA Tour event since 2013.
The 42-year-old carded a 65 on Saturday to give him a three-shot lead heading into Sunday with Rory McIlroy and Justin Rose in close contention.
All eyes will be on the American to see whether he can complete his remarkable 2018 comeback campaign at the Tour Championship.
He has remained calm throughout the weekend having been at the top of the leaderboard since the first round.
However, speaking yesterday, Woods admitted he is still surprised at how far he has come in such a short space of time.
“In March, I didn’t really have a golf swing yet,” Woods said.
“I was still trying to figure out how to play.
“My body is so different than it was then, and my equipment is so different than it was then, too, as well, because of my body and because of my swing.
“I’ve gone through a lot this year to get myself to this point.”
