American John Hahn recorded a stunning 12-under-par round of 58 at the European Tour's qualifying school this afternoon.
The 25-year-old recorded six pars and 12 birdies at the PGA Catalunya Resort in Girona, Spain, going out in 30 before coming home in 28 at the par-70 course.
Although a fabulous score, Hahn's achievement won't go down in official records because preferred lies are being used in the event.
Hahn began the day 104th out of 150 players but shot up the rankings thanks to his low score.
The top 70 after four rounds make it to the final two rounds, where the top 25 are then awarded with cards for next season's Tour.
