DURBAN, December 13, 2013 (AFP) - Spain's Campillo and South African Nel both broke the 60 barrier although they will not enter the record books as preferred lies were allowed on Mount Edgecombe's saturated fairways.
Following lengthy delays on both Wednesday and Thursday, organisers were forced to reduce the tournament to 54 holes after another three-hour delay on Friday.
Campillo had two eagles and seven birdies to reach 11 under par for the tournament, while first round leader Brooks was 12 under with seven holes of his second round remaining when darkness brought play to a halt.
England's Matthew Baldwin shot a 62 to share the clubhouse lead with Campillo, with home favourites Branden Grace, Oliver Bekker and Dawie van der Walt on ten under.
"We play other par 70s on Tour, but you still have to shoot 59 and I'm pretty happy with the way I finished," said 27-year-old Campillo.
"I was never close to 59 before, but in the Dutch Open I was eight under with three holes to go on a par 70. Finishing with three birdies would have put me on 59 but I finished par-par-bogey. That helped me a lot today, because finishing well was important and I did it."
Despite his 59, Nel was back on four under for the tournament after an opening 77.
