Cristobal del Solar carded one of the lowest scores in the history of professional golf with a 13-under-par 57 in the Astara Championship.
The Chilean made two eagles and nine birdies in the event in Colombia on the Korn Ferry Tour, the developmental circuit that sits below the PGA Tour.
The 30-year-old shot his 57 on the Pacos course, the shortest on the tour and almost 9,000ft above sea level.
Ireland’s David Carey carded the only other 57 on a professional tour.
That was at the Cervino Open in 2019 on the Alps Tour, the third tier in Europe below the European Tour.
Jim Furyk’s 58 at the Travelers Championship in 2016 is the lowest round on the PGA Tour.
It was matched last year by Bryson DeChambeau in a LIV Golf event while Ryo Ishikawa and Kim Seong-hyeon have made 58s on the Japan Tour.
Del Solar’s round at the Bogota course – which sits at high altitude, where the ball flies about six per cent further because of the thinner air – is the best in a PGA Tour-sanctioned event.
The world number 259 could have gone even lower but missed a 15-foot putt for birdie on the par-four 18th that meant he made par on his final three holes.
