Dan Bradbury kept his cool to secure his second Joburg Open title after a hectic final round in South Africa.
Hennie du Plessis looked in pole position for victory when he reached the turn with a three-shot lead but just as the chasing pack closed in, he dropped three shots at the 15th and 16th to fade out of contention.
Casey Jarvis, who was looking to join an elite group of players with three consecutive DP World Tour event wins, surged into the lead late on, but bogeyed the 17th before missing a birdie putt at the last which would have extended the tournament.
Brandon Robinson Thompson had gone down the final hole with a one-shot lead, but three-putted to finish alongside Jarvis at 16 under.
Bradbury was standing in the 18th fairway as his fellow Englishman bogeyed the last to give him a one-shot advantage, only to overshoot the last green.
However, he produced a stunning recovery shot for a tap-in par which sealed his third DP World Tour success and second at Houghton Golf Club.
"It sounds pretty good," Bradbury said. "I thought I lost it on front nine, I had so many chances and I just didn't take anything.
"It feels really good to put it together on the back nine, probably wasn't expecting it as Hennie was playing so well, but yeah, feels amazing.
"Casey and Brandon were obviously playing amazing because I saw their names on the leaderboard all the way round - it was tight all the way round wasn't it - but I somehow managed to get it done in the end.
"It's probably similar to Wakefield where I grew up. It's quite tight, tree-lined and got to drive it well. I did that and putted pretty solid this week, although it didn't feel amazing, but got the result and that's all that matters."
Du Plessis opened up with a birdie, but his two-stroke overnight lead still remained after Bradbury and Robinson Thompson had also picked up a shot at the first.
He improved his advantage to three with a lovely 15-foot putt at the fourth as he became the first person to reach 16 under.
His momentum did not stop there and when he rolled in his third birdie of the day at the next, Du Plessis was four clear.
Alex Fitzpatrick made his move with birdies at the third, fifth and eighth helping him climb to 15 under before he was joined at that mark by Robinson Thompson.
Fitzpatrick's double bogey at the ninth saw his challenge fade, but Du Plessis reached the turn with his three-shot lead restored thanks to a birdie at the same hole.
Robinson Thompson birdied the tenth and 11th to trim the leader's advantage to one and he soon moved into the joint lead at 17 under when Du Plessis dropped his first shot at the 12th.
The Englishman nudged ahead with a birdie at the 14th, the same hole where Jarvis had rolled in his sixth birdie of the day from long range to sit ominously one behind.
Jarvis, Du Plessis and Robinson Thompson shared the lead at 17 under after the latter bogeyed the 15th, before Du Plessis slipped down the leaderboard.
It was advantage Robinson Thompson when Jarvis missed his par putt from six feet at the 17th, but he was not alone at the summit.
Bradbury was quietly going about his business and when he rolled in his seventh birdie at the penultimate hole, he was at 17 under.
Jarvis narrowly missed a birdie putt to join the pair at the top before Robinson Thompson bogeyed the last to hand Bradbury the initiative.
He only needed a par to secure his third DP World Tour win and his brilliant recovery shot meant he did just that for a final-round 65 and a 17-under-par total.
Jarvis and Robinson Thompson both carded 66s to share second, while Du Plessis was two shots further back at 14 under.
Frenchman David Ravetto finish in solo fifth at 13 under, while Fitzpatrick, Emirati Adrian Otaegui and South African pair Daniel van Tonder and Loius Albertse finished one shot further adrift.
