"I knew I was playing well and had made a few birdies".
The 42-year-old American, who hasn't won a major title since the 2008 US Open and hasn't won any event in five years, sank a 14-foot birdie putt at the second, a five-footer to birdie the par-3 third and a 10-foot birdie putt at the fifth hole, then dropped in a 15-footer to salvage par after finding a bunker at the par-3 sixth.
Finau was among five players who accompanied Furyk to France this summer for a scouting trip at Le Golf Nacional, the host course of the September 28-30 Ryder Cup matches.
Defending champion Justin Thomas was at 2 under through seven holes, while Rory McIlroy was frustrated with all pars in his seven holes.
"I'm in a lot better position than I was when I came out here this morning, which is great", Thomas said.
He picked up one last birdie when he reached the green in two on the 597-yard 17th hole and two-putted, sending him to a 66. Tiger Woods sits tied for 24th at minus-3. "Everyone is bunched. On top of that, if you hit the ball well enough, you'll leave yourself in the right sections". One more record was set Saturday morning when the cut was at 140, breaking by one shot the lowest score to make the cut. If you do that well, and, obviously, in there you're going to make those putts.More news: Pence, Pentagon promise 'Space Force' by 2020

The PGA have confirmed their third-round tee times, with Woods out on the course at 12:21pm local time.
"Honestly, I haven't hit it great, up to my standards, these first couple days", Finau said.
Woods, a 14-time major champion in the eighth month of his comeback from spinal fusion surgery, was 3-under after seven holes.
Paul Dunne, meanwhile, will also miss the cut as the Greystones native is five over with one to play.
Kisner shot 29 on the back nine - his first nine - and was threatening to shoot a tournament-record 62 but bogeyed the final hole and settled for 64. They have also finished their first two rounds.
Finau, who was doing an audition of sorts for a spot on the Ryder Cup team, being paired with Ryder Cup captain Jim Furyk, impressed the captain by starting out with seven birdies on the first eight holes, including the first five.
Kisner, playing in the same group as Woodland, came up short of the green at No. 9 and made bogey for a 64.
