South Africa's Jbe Kruger shot a 5-under 67 on Friday at Leopard Creek to take a four-stroke lead in the Alfred Dunhill Championship.
Kruger was 13 under in the event sanctioned by the European and Sunshine tours. Seeking his first European tour title, Kruger had an eagle, five birdies and two bogeys.
He followed his eagle on the par-5 second with consecutive bogeys, but recovered to string together four birdies without dropping a shot coming in.
''I didn't have fun in the early part of my round, but later I did have fun,'' Kruger said. ''I think you should have fun, otherwise, why play? If you enjoy it you tend to play better.''
Chile's Felipe Aguilar (64), Scotland's George Murray (69) and England's Seve Benson (71) were tied for second.
Kruger took advantage of a late slip-up by countryman George Coetzee, who led by four strokes but dropped five shots on his last three holes for a 71 that left him six shots behind at 7 under.
Two-time defending champion Pablo Martin of Spain missed the cut with rounds of 81 and 82. He was trying to become the fifth player in European Tour history to win an event three times in a row.
