FINAL LEADERBOARD:Richard Sterne claimed victory at the second extra hole of a three-way play-off to capture the Joburg Open.
Sterne fired seven birdies in a final round 65 to finish on 18-under with Magnus Carlsson and Garth Mulroy.
Northern Ireland's Darren Clarke, who began the final round three shots back tied for fifth, had five birdies in a 68 to finish fourth three shots adrift.
Overnight leader Mark Murless, who held a two-shot advantage, ran up five bogeys and was tied for fifth place.
Mulroy was in sole possession of the lead with two holes to play after a birdie on the par-three 16th, but could only par the last two holes.
Carlsson and Sterne, however, birdied both the 17th and 18th holes to secure their places in the sudden-death play-off.
All three players in the play-off birdied the par-five 18th first time around, Sterne securing his four after a marvellous shot into the green with a four-iron from the fairway bunker.
Sterne found the putting surface in two once more when it was played again, and safely two-putted for victory, his opponents unable to match him having found the fairway trap.
It capped a remarkable day for the 26-year-old, who bogeyed the first hole but played the last nine of regulation play in a mere 31 strokes having begun the day four shots behind the leader in a share of 11th.
Sterne, the highest-ranked player in the event, was three-over after three holes of the opening round.
"Any time you're favourite to win or anything like that, I think it's a little bit more pressure.
"I didn't get off to a good start at all. I think I was three over at some stage, but I came back strong and that's what it's about."
