The first man to shoot a round under 60 on the PGA Tour was Al Geiberger on 10th June 1977 when he carded a 59 in the second round of the Danny Thomas Memphis Classic. He eventually won by two shots from South Africa’s Gary Player.

After Geiberger’s record-breaking round, five men also shot rounds of 59 on the Tour:

The only official round under 60 on the PGA European Tour is 59 by Oliver Fisher (England) in the 2018 Portugal Masters at Villamoura, Portugal.

Jorge Campillo (Spain) and Colin Nel (South Africa) both recorded rounds of 59 in the 2013 Nelson Mandela Championship at Durban. A joint Sunshine Tour/European PGA Tour event, the scores were not ratified as official because preferred lies were in operation at the time due to the bad weather conditions.
