Spain’s Jorge Campillo and South African Colin Nell shot stunning 11 under par 59s on the second round of The Nelson Mandela Championship presented by ISPS Handa.
However the two rounds will not enter the record books due to a preferred lie rule in effect allowed on the rain-softened Mount Edgecombe fairways.
Campillo posted seven birdies and two eagles to join England’s Matthew Baldwin with the clubhouse lead on 11 under par but one shot behind England’s Daniel Brooks who leads on 12-under par after 11 holes of his second round.
Nell went from shooting a first round 77 to improve by 18 shots with his round of 59 that left him in a share of 27th place at four under par.
While there has been a number of 59s on the |PGA Tour the European Tour still awaits for its first official 59.
Another three hours of play was lost to rain on Friday morning, which added to the lengthy delays on Wednesday and Thursday forced organisers to reduce the event to 54 holes.
Several players had to finish their first rounds when play did resume at 09:00, but nobody was able to surpass Daniel Brooks eight under par 62 from the opening day.
However, first South African Oliver Bekker and then Campillo soon raced past the Englishman when they went out for their second rounds for a quick turnaround.
Bekker birdied the tenth – his first – then leapt into the lead with an eagle at the long 12th.
Another birdie followed at the 13th, and a fine approach to five feet at the 14th saw him go five under through five holes and 11 under for the week.
However, the 29 year old faded slightly with three bogeys and two birdies from that point leaving him with a 66 and share of third place alongside compatriot Branden Grace.
Campillo pitched in for a second eagle of the day at the fourth – like Bekker he made a three at the long 12th – and added seven birdies as he chases a first European Tour title.
Baldwin has never finished higher than fifth, but made six birdies and an eagle on the 12th in his second round 62.
Qualifying School graduate Brooks had not begun his second round when the leaders reached the clubhouse, and was likely to have to return early on Saturday morning to complete his second round.
