In winning the Sony Open in Honolulu - he finished seven shots ahead of Olympic gold medallist Justin Rose with world No 5 Jordan Spieth a shot further back - with a 27-under-par 253 aggregate, Thomas set a new 72-hole record for the US circuit.
The wire-to-wire win, which came hot on the heels of an equally impressive success in the SBS Tournament of Champions at Kapalua seven days earlier, saw the 23-year-old become the youngest player to card a 59 with his opening salvo at Waialae Country Club.
Thomas also set the lowest 36-hole total - 123- in PGA Tour history before equalling the record of 188 for the 54-hole mark.
“It’s awesome, it’s been an unbelievable week, unforgettable,” said Thomas after signing off with a 65, which included an early bogey at the fourth before carding birdies at the eighth and ninth to settle any nerves. He then stormed home in 31 after picking up further shots at the 11th, 12th, 14th and 18th.
“I was really nervous (before the round),” added Thomas, who has now won three times in five PGA Tour events this season and four times in total. “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 a par putt I made on six was huge.”
The previous lowest 72-hole score was 254, made by Tommy Armour III as he clinched victory in the 2003 Valero Texas Open.
“I remember someone saying in a press conference I needed 10 under over the weekend, so I told Jimmy (caddie Jimmy Johnson) with two holes left, I was like ‘we need to get one of these last two’. It’s awesome,” admitted Thomas.
Knox tied for 11th after a closing 69 for 14-under. The Scottish No 1 was two-over after 11 before picking up three birdies in the last seven holes

Craig, Paul’s oldest son, came home in 32, having covered the same stretch in just one shot more in the opening round.
“ I got off to poor starts on both days, having been +2 through four then +2 after six,” said Lawrie, who warmed up for the 2017 season with his dad and younger brother, Michael, out in Abu Dhabi over the festive period.
“But I really solid after that and hit an 8-iron to a foot for eagle at the par-5 last to give me second on my own.”
Among those to finish behind Lawrie were Irishman Cormac Sharvin and Englishman Jimmy Mullen, both members of the GB&I winning Walker Cup team in 2014.
“I have two more events out here at Penina and Palmares before heading home,” added Lawrie.
