Haydn Porteous won his first European Tour event at the Joburg Open on Sunday, firing a bogey-free 69 for a two-shot victory.

The 21-year-old's win was the second straight for a South African on home soil following Brandon Stone's victory in the SA Open last week.

It also makes it three South African wins out of five this season after Charl Schwartzel's victory at the Alfred Dunhill Championship.
