Lawrence took a three-shot lead into the final round on Sunday and was still two clear with five holes remaining after recovering from a double bogey on the 5th with birdies on the 6th, 9th and 12th.

Wallace closed the gap with his fourth birdie of the day on the 14th and found himself in a tie for the lead when Lawrence was unable to save par from a greenside bunker on the 16th.

Both men then parred the last two holes to finish tied on 18-under-par, but Wallace three-putted the first extra hole – the 18th – from the back of the green to hand Lawrence the title.

"It's a privilege to be able to take this victory," Lawrence, who won the Joburg Open in November after the event was reduced to 36 holes, told Sky Sports.

"There's so much history going around this event, all the past champions, so can't wait to get my hands on that trophy.

"I was happy with my patience this week and just so pleased to be able to win."

The victory will take Lawrence from 131st in the world rankings to inside the top-100 and he added: "It's a dream come true.

"Growing up you always want to be in the top-100 in the world and to achieve it is quite emotional. It's awesome."

On a sun-drenched, still day in the scenic Swiss Alps, all the top-20 finishers shot under par rounds in the 60s, including 2016 Masters champion Danny Willett, whose 66 left him tied for ninth at 13-under.

England's Richard Mansell finished two shots outside the play-off following a final round of 67, with Scotland's Scott Jamieson, France's Antoine Rozner and Spain's Jorge Campillo sharing fourth place on 15-under.

Leading Australian, tied for 51st, was veteran Scott Hend, who shot a final-round 71 to finish at six-under, one stroke ahead of his compatriot Dimitrios Papadatos, who recorded a concluding 70.
