In-form Clarke outdone by local lad
The 40-year-old Ulsterman shot an eight-under-par 63 over the easier West Course at Royal Johannesburg and Kensington, but little-known South African Neil Schietekat then went one better.
Ranked only 1,074th in the world, Schietekat turned his form in the event on its head. He missed the halfway cut the last two years after opening with scores of 79 and 77.
