Thriston Lawrence claimed his second DP World Tour title at the European Masters after edging out Matt Wallace in a play-off at Crans-sur-Sierre.
The 25-year-old climbed into the world's top 100 for the first time as he held his nerve to earn a maiden European Tour success over four rounds.
Lawrence, who triumphed at the 36-hole Joburg Open last November, also became the first South African winner of the title since Ernie Els in 2003.
Following a stunning 67 on Saturday, the world number 129 held a three-shot lead over Wallace heading into the final round of his first European Masters appearance.
He appeared to pick up from where he left off with a magnificent 32-foot birdie on the third hole. However, a double-bogey on the fifth enabled Wallace to close the gap.
The Englishman carded an impressive 66 as he sought a first European Tour victory in nearly four years, while Lawrence's bogey on the 16th culminated in the sixth play-off in 10 editions of this event.
As both players returned to the 18th, Wallace was aiming to maintain his perfect play-off record, having prevailed at the Hero Indian Open and Made in Denmark in 2018.
But there was to be no joy for the 32-year-old this time around. Indeed, a sloppy approach culminated in him pulling a tricky five-foot par putt to tie, handing Lawrence the title.
"It's a privilege to be able to take this victory," the South African said. "There's so much history going around this event and all the past champions, so I can't wait to get my hands on this trophy.
"I was actually quite fine [with going to a play-off]. It's a tricky golf course; you can lose a few shots, especially around [holes] 14 and 15. On the par-fives, you can make a silly mistake and another guy can make birdies.
"I'm just happy with my patience around this weekend; I'm just so pleased to be able to win this.
"Growing up, you always want to be in the top 100 in the world, and to achieve it is quite emotional."
