Denmark's Morten Orum Madsen and England's Chris Lloyd both have a chance to win on the European Tour less than two weeks after coming through the qualifying school.
After two washed-out days at Royal Durban in South Africa the inaugural Nelson Mandela Championship was cut to 36 holes.
Madsen birdied three of his last five holes for a 60 (par is 65) and shares the lead with local hope Tim Clark, while 20-year-old Lloyd is only one behind along with another of the home contingent, Lindani Ndwandwe.
Former Players Championship winner Clark set the target earlier in the day and said: "It wasn't that easy out there, but I was amazed at how good the greens were with all the rain they had.
"I made some good putts and obviously gave myself a lot of chances.
"If it is going to be a two round tournament you've got to go low. Normally you can sort of pace yourself, but right now you've got to be aggressive.
"I was hitting a lot of drivers. I was certainly not trying to play it safe.
"We obviously can't tell what the future holds, but I do hope we get to play some more golf."
After the disruption on Thursday and Friday the objective is to get 36 holes played by Sunday evening, but if there are any more delays and it is possible to finish the second round on Monday then that will be done.
"If it is going to be a two round tournament you've got to go low" - Tim Clark
Clark's card included three successive birdie twos on the back nine. That was because the 13th and 14th were among four holes made into par threes because of the conditions.
English pair David Horsey and Matthew Southgate were among those who came in with 62s to be in joint fifth place.
