Justin Rose soared back to the top of the world rankings after edging out Haotong Li in a thrilling finish at the Turkish Airlines Open.
Brandon Stone is the home hero at South African Open
Brandon Stone ticked off his first European Tour victory with a topsy-turvy final round at Glendower to beat his compatriot Christian Bezuidenhout by two shots.
England's Daniel Brooks was a shot behind in third after a bogey on the 18th.
South African Stone led by five after two early birdies but six bogeys (and a birdie) in the next seven holes meant he was two behind Brooks.
But four birdies in the next five turned the tables again and he held on with two pars, of just five in total, for victory.
Stone only got through the Challenge Tour in 14th spot after a closing 68 in the final event in Oman.
Before that he studied at the University of Texas, as Jordan Spieth did, and is thought to be a brilliant ball-striker.
What Stone said: "I don't have the vocab to describe how I feel right now. That round was the most up-and-down round that I've ever had in my life, without a doubt in my mind.
"After making that bogey on the 11th I said to myself, 'You're still right there, you've been playing great for three days now. Let's just keep it going, just hit the fairway on 12. I hit a great one down 12, left myself my favourite yardage. I made an incredible shot and it just swung from there."
