Sweden's Marcus Kinhult was lost for words after he produced a brilliant finish to claim his first European Tour title in a thrilling climax to the British Masters at Hillside.
Kinhult's chances looked to have gone when he surrendered a one-shot lead with bogeys on the 15th and 16th.
But the 22-year-old birdied the final two holes to card a 70 and get to 16-under 272 – to finish a shot ahead of defending champion Eddie Pepperell (66), Matt Wallace (71) and Scotland's Robert MacIntyre (68).
Pepperell had set the clubhouse target on 15 under after a closing 66 before MacIntyre produced a stunning eagle-birdie finish to join him at the top of the leaderboard.
A four-man play-off looked on the cards when Kinhult birdied the 17th and playing partner Wallace missed from four feet.
But after Wallace also missed for birdie on the last, Kinhult holed from 12 feet to seal a remarkable win and secure the Stg500,000 (AU$930,000) first prize.
"I'm speechless, I don't know what happened the last two holes," Kinhult said.
"I was behind Matt and he looked really solid but I birdied 17 and all of a sudden I had a putt to win; it's incredible.

"I have never felt that pressure before. Richie (Ramsay) gave me a good read so I just tried to do the same thing and holed it."
Tournament host Tommy Fleetwood (73) had an eagle putt on the 11th to get within a shot of the lead but left it short and dropped three shots in the last seven holes to finish in a tie for eighth at 10 under.
The best Australian was Dimi Papadatos, who shot a one-under 71 to be tied for 15th at nine under, while Scott Hend (73) and Lucas Herbert (69) finished in a share of 35th at five under.
Pepperell began the day five shots off the lead shared by Kinhult and Wallace but carded six birdies in a flawless 66 – the joint-lowest score of the day.
"I kind of set myself a target of 17 under at the turn and was not far off that," he said.
"But fair play to Marcus. He's been a good player for a while, so it's good to see."
