England's Sam Horsfield galloped around Streamsong Black in the United States with a round of 14-under 59 last week.
Horsfield, 23, posted 10 birdies and two eagles on the Gil Hanse-designed course in Florida. He went out in 29 shots before returning in 30.
The Manchester-born player is currently ranked 222nd in the world right now, but if his current game is anything to go by then that ranking could be whittled down to the top 100 soon enough when golf returns on the PGA Tour next week, and on the European Tour from July 22.
Horsfield's playing partners were also on fire, judging by the scorecard posted on social media, with 'Sierra' shooting a 5-under 68 and 'Gordo' with a 4-under 69... yes, just the 23-under par for the three players.
The Englishman, who has gone as low as 62 on the European Tour before, has only made three cuts in seven starts on the European Tour this season.
Horsfield has lived in the United States since he was five years old.
He was selected to play at the 2015 Walker Cup at Royal Lytham & St Annes Golf Club but then later withdrew before the event as he thought he may not have the correct visa and was worried about being allowed back into the United States after the event.
Horsfield, who was mentored by Ian Poulter back in the day, was runner-up at the 2016 Western Amateur and then turned professional the year after in 2017.
