SUN CITY, South Africa- Zimbabwe's Nick Price fought off an early challenge from countryman Mark McNulty on Saturday and opened a four-stroke lead after the third round of the Dimension Data Pro-Am.
McNulty, who shared second place at the start of play, three shots behind, twice came within one stroke of the defending champion.
Price finished the round with a 4-under-par 68 and a 12-under 204 total. McNulty had a 69 for 208.
American Bruce Vaughan, who began the round tied for second with McNulty, was disqualified on the first hole for using preferred lies instead of adhering to the tournament's temporary rule of lifting, cleaning and replacing a ball on the same spot.
