The 14-time major winner will make his eighth Ryder Cup appearance – and first since 2012 – later this month after being named as a wild card by US captain Jim Furyk.
And the PGA Championship runner-up continued his good form with an eight-under-par 62, which was later matched by Ryder Cup rival Rory McIlroy.
The 42-year-old’s lowest opening round since 1999 would have been bettered by McIlroy had the Northern Irishman not bogeyed two of his last three holes.
Woods was using the 19-year-old putter which earned him 13 of his 14 major titles, having taken the decision to try a third different flat stick in as many weeks.
He told tigerwoods.com: “It feels good. I know the release point and I know how it swings.
“And my body morphed into a position where it understands where it needs to be to release the putter.”
Xander Schauffele is a shot off the lead while Billy Horschel, Peter Uihlein, Justin Thomas and Alex Noren all carded a six-under 64.
Rickie Fowler is in a four-man group on five under on his first appearance of the FedEx Cup play-offs.
Golf legend Tiger Woods cannot wait to make his playing return at the Ryder Cup.
United States captain Jim Furyk named Woods, Phil Mickelson and Bryson DeChambeau in his team on Tuesday – with Woods moving to the playing side. Furyk named David Duval, Zach Johnson and Matt Kuchar new vice captains.
“I haven’t been part of the team playing-wise for six years,” Woods said. “This year to have the honour of being able to play again is beyond special.”

Tiger Woods‘ children are much older now than they were the last time he was seriously competing in majors.
As such, they know what their dad is going through as he tries to get back to being a force in the game.
Woods showed plenty of promise at The Open this past weekend, when he was in contention for the Claret Jug in the final round before settling for a top-10 finish.
Afterward, he spoke about how much it means to him to be able to compete in front of his kids.
“I told them I tried and I said hopefully you’re proud of your pops for trying as hard as I did,” Woods said.
