Jordan Spieth was basking in the Hawaiian sun until his day fell apart in stunning fashion with a late quadruple-bogey to finish six shots back of first round Sony Open leaders Zach Johnson and Chris Kirk on Thursday.
Twice major victor Johnson carded a bogey-free seven-under 63 in the afternoon wave that included a birdie at 18 to grab a share of the lead with early starter Kirk, who stormed into the clubhouse with four birdies over the final six holes.
Kirk and Johnson opened with seven-under 63s to share the overnight lead.
Spieth declined media requests after he signed his card, instead taking 15 minutes to sign autographs.
Spieth hit four trees with four shots on the par-4 eighth hole - his 17th of the round - an episode that began with his tee shot caroming off a trunk and into a ditch.
Thomas, the defending champion who broke the PGA Tour's scoring record previous year, played in the afternoon. The Alabama alumnus won a bet involving the college football national title game that required Georgia graduate Kevin Kisner to wear a Crimson Tide jersey from the tee box to the green. "I really had no expectations whether I was going to play good or bad after having some time off". Johnson countered with four birdies on the front and three on the back. He missed that, though the two-time major champion wasn't too discouraged.
He made eight birdies and shot 69.
But his tee shot pulled left off the tee and collected with a tree, knocking it down into the rough.
He missed two putts inside five feet and needed 30 putts in his round with two three-putts.
