The 25-year-old has strung together 502 points over the course of the season, beginning with a share of third at the Golden Pilsener Zimbabwe Open.
The Chase to the Investec Cup offers up points based on the prize fund of each tournament and last week’s Lion of Africa Cape Town Open carried a total of 3000 points.
That was good news for Van Rooyen, who picked up enough points to rise into the top 10 in the Chase to the Investec Cup ahead of the this week’s Alfred Dunhill Championship.
Brandon Stone picked up 250 points for his victory at Royal Cape Golf Club, which rocketed the 22-year-old to 38th in the standings.
Meanwhile, points leader Dean Burmester was away competing at the European Tour’s final stage of qualifying school and gained no further ground. He remained in pole position with a total of 1,096 points.
Van Rooyen has finished outside the points just once in his 10 starts during the Chase to the Investec Cup and will be keen to add to his tally, especially after making the top 10 last week.
