Louis Oosthuizen shot 7-under 65 to get to 14-under and held a one-shot lead over the little-known Jacques P De Villiers, who caught the eye with a second-round 67. De Villiers ranked 984th in the world, birdied the 18th to get to 68 in the third round and a total of 13-under.
Sebastian Soderberg, who teed off early on the second day, blazed the spanking new La Reserve Links course with a card of 7-under 65 that took him to the top of the leader board at the Mauritius Open as the event neared the halfway stage.
