Louis Oosthuizen insists he will start the South African Open all over again after shooting a brilliant 62 to claim a first-day lead.
The home favourite, bidding to win the tournament for the first time, carded nine birdies on the Bushwillow course in Johannesburg on Thursday.
But he will reload for his second round on the Firethorn course, which will play host to the whole field after the cut.
Oosthuizen told europeantour.com: "Anytime, anywhere, nine-under is always going to feel nice. It was one of those rounds where you don't really look at any scoreboard or your card, you just play.
"There's a long way to go. I've got one of the courses out of the way, so now I just focus on the main course for the week and it feels like a new tournament starting tomorrow for me."
American Kurt Kitayama and Zambia's Madalisto Muthiya are a shot behind on eight-under par with Oosthuizen's compatriot Zander Lombard lying fourth on seven-under.
Irish pair Michael Hoey and Gavin Moynihan are both well off the pace and both signed for rounds of 75, leaving them on +4. Neil O'Briain is a shot further back on +5.
