He came up short of the green, chipped too strong and made bogey for a 64, leaving him one shot out of the lead Friday.
Finau, who double bogeyed No. 6 after his five birdies to start, did not have a par in the second round until the 10th hole.
As the final groups teed off Woods was four shots off the lead, but he was far from alone in taking advantage of the ideal conditions, with defending champion Justin Thomas making a birdie at the first and 2015 victor Jason Day picking up shots on the first and third.

The 48-year-old Mickelson, who won the WGC-Mexico in the spring, played on his first U.S. Ryder Cup team in 1995 and has made every team since, including two years ago at Hazeltine, where the Americans won for just the third time in his 11 appearances.

"After the Open I wanted to do something different, just change the way I thought I on the golf course and he's been brilliant so far". "Its soft, it's gettable, and you can't just go out there and make a bunch of pars, you're going to have to make some birdies". And now we're going out on a Saturday afternoon in the mix at the PGA, it's great. I have my dad here to watch.
