South Africa's to win the tournament by two strokes.
Coetzee was playing in his first European Tour event since the Qatar Masters in March.
He played in the opening three Sunshine Tour Rise-Up Series events and entered this week's event hot off the heels of a Sunshine Tour victory where he won the Titleist Championship at Pretoria Country Club.
It was the second win from a South African golfer on the European Tour this year after Branden Grace won the South African Open in January.
