Justin Thomas ended his record-breaking week in style as he bettered the previous best 72-hole score on the PGA Tour to claim a seven-shot victory at the Sony Open in Hawaii.
Thomas started the event by becoming the youngest man to register a sub-60 round on the PGA Tour with an opening 59 in Honolulu, and he followed that up by setting the lowest 36-hole total before equalling the record for the 54-hole mark.
That gave the 23-year-old a seven-shot lead heading into the final day and it was one he did not surrender as a closing 65 took him to 27 under par overall which secured back-to-back victories on the PGA Tour.
After backing up his win at last week's SBS Tournament of Champions, Thomas told the PGA Tour's website: "It's awesome, it's been an unbelievable week, unforgettable.
"I was really nervous (before the round). I just had a hard time getting in a comfortable mindframe. I felt like I was doing what I needed to do and making some pars, besides that bad bogey on four, but that par putt I made on six was huge."
Thomas did bogey the fourth hole but four birdies in the space of five holes from the eighth dampened any hope the chasing pack had of catching up with the American.
He picked up another shot at the 14th and tapped in for a birdie on the last to ensure his name would go in the record books once more after carding a score of 253 this week.
The previous lowest 72-hole score was 254, made by Tommy Armour III as he clinched victory in the Valero Texas Open in September 2003.
Justin Rose finished runner-up following a score of 20 under par, with a closing 64 enough to finish above Jordan Spieth, who finished with a 63.
