Thomas sets PGA Tour 36-hole scoring record with 2nd-round 64

Justin Thomas made history Thursday with a 59, becoming the seventh player in PGA Tour history to achieve the feat. One day later, he set a new 36-hole Tour scoring record, carding a 6-under-par 64 at Waialae Country Club in the second round of the Sony Open.

The 23-year-old arrived at the par-5 9th at 1-under, but proceeded to birdie the next four holes, making several accurate wedge shots, like this one at No. 12:

"Yeah I played great. I really hit a lot of quality shots today," said Thomas after his round. "The three bogeys I made were terrible, they were lack of concentration or just not playing smart."

The world No. 12 sent his tee shot into the greenside bunker at the par-3 17th and failed to make par, meaning he needed a three at the home hole to break the record. He drove his ball into the left rough, then hit his approach from 208 yards to eight feet, before calmly stroking it in for the eagle and the record.

The Kentuckian's two-day total of 123 broke the mark of 124 that was set by Pat Perez in 2009 and then equaled by David Toms in 2011 and Jason Day in 2015.

"Obviously I had a great day out there, to finish with that eagle was huge, the bogeys on 13 and 17 were a bit of a bummer, but I made enough birdies on the back nine to counteract that."

Thomas leads by five over Gary Woodland, who recorded his second straight 64.
