Home favourite Brandon Stone concluded a stunning four days with a final-round 67 to win the Alfred Dunhill Championship by seven strokes.
The South African finished 22 under for the tournament at Leopard Creek, leaving compatriot Richard Sterne as his nearest rival.
Having started Sunday's round three shots ahead, Stone maintained his fine form on home soil, with a run of four birdies in five holes after the turn cementing his spot at the top of the leaderboard.
The 23-year-old, who won his first European Tour title in South Africa in January, was even relaxed enough to take the time to do some wildlife watching, as a bathing hippopotamus caught his attention.
Stone finished with a birdie following a superb approach to the par-five 18th to match his first-round score, having made 66s on Friday and Saturday.
"I knew I could score and I holed some great putts at the first three holes on that back nine which really got the momentum going," he said.
"I just played some incredible golf the whole week to be fair.
"I think my ball striking this week was superb from the first hole to the last.
"That score that I shot this week - 22 under par around here is not a simple task - to do that is obviously quite something."
Sterne did all he could to apply pressure, matching Stone's total with a blemish-free scorecard, while Thomas Detry was a further two shots back in third.
Englishman Paul Maddy's 65 was the lowest score of the day, while David Drysdale - whose 64 on Saturday was the best of the tournament - faded badly with a last-round 73.
