The R850,000 Investec Royal Swazi Open will finish on Sunday after a late-afternoon thunderstorm disrupted play on the scheduled final day on Saturday.
The tournament is played on a modified stableford system, with eight points for an albatross, five for an eagle, two for a birdie and none for par. One point is deducted for every bogey and two for double or worse.
Justin Walters and Christiaan Basson were leading on 44 points each at the break, and Divan van den Heever was four points back on 40. That threeball was on the 12th fairway where they will resume at 6.30am on Sunday.
Alex Haindl had made a charge, but a dropped shot on the 13th saw him slip back to 39 points.
Andre Cruse was the leading player to have finished, with 31 points.
