Justin Thomas made history for the second time
in two days as he set a record for the lowest 36-
hole total in PGA Tour history with his score of
123 at the Sony Open in Hawaii.
The American, 23, became the youngest man to
card a sub-60 round with an opening 59 in
Honolulu.
He followed it up with 64 on Friday to move to 17
under par - five shots clear of Gary Woodland at
the halfway point.
England's Justin Rose is among those in a tie for
third on 10 under par.
Thomas, who last week won the Tournament of
Champions , also in Hawaii, had six birdies and
eagled the last for the second day in a row. He told the PGA Tour's official website: "It's cool,
any time you can get your name in the record
books is awesome.
"I had no idea until I finished, until I signed and
[someone in the scoring tent] said '123', and I was
like 'man, I'd love that a couple more times in my
career'."
Olympic champion Rose made seven birdies and
one bogey to move to 10 under alongside
American pair Hudson Swafford and Zach Johnson.
Scotland's Russell Knox is among a group of
players on nine under, with world number five
Jordan Spieth a further shot back.
