Henrik Stenson will take a commanding eight-shot lead into the final round of the Nedbank Challenge in Sun City after a superb third round.
The Swede shrugged off a delay for lightning to card a seven-under-par 65 for a 17-under total of 199 at the Gary Player Country Club.
World Cup-winning team-mate Robert Karlsson is Stenson's nearest challenger on nine under after a 67 on Saturday, with South African Rory Sabbatini three shots further back following a 72.
Stenson went to the turn in 34 with two birdies and stormed home in 31 with five birdies in seven holes to leave the field trailing in his wake.
England's Lee Westwood is a distant 13 shots off the pace after a 70 while Luke Donald continued his comeback from a serious wrist injury with a 71 to improve to one over par.
Former European number one Justin Rose is a shot back on two over after a third-round 72, while Spain's Miguel Angel Jimenez - pipped to World Cup glory by Stenson and Karlsson in China on Sunday - continues to prop up the 12-man field on eight over.
