Mervyn King crashed out of the PDC World Darts Championship at the first hurdle after an epic 3-2 defeat to former BDO runner-up Dean Winstanley at Alexandra Palace.
The unseeded Winstanley eventually came through the deciding set 6-4 to reach the second round in his first appearance at the PDC event.
Both players missed darts for the match in the deciding set but Yorkshireman Winstanley regrouped to win three successive legs and snatch a thrilling victory.
Speaking to Sky Sports afterwards, Winstanley, who fired in ten 180s during the win, said: "That was a battle. I've had battles, why can't I have straightforward matches? I'm totally blown out but I'm really, really happy."
King added: "Dean played better than me today. He didn't play well, I didn't play well and it wasn't the game we were hoping for. But at the end of the day he played better."
Meanwhile Steve Beaton and Wes Newton both won 3-0 to safely progress.
Beaton - the 1996 world champion - will face James Wade in the second round having accounted for Kyle Anderson despite producing a poor strike-rate when it came to hitting doubles.
Beaton's heavy scoring ultimately proved the difference as tournament debutant Anderson - who had darts to win both the first and second sets - struggled to check out.
"I had to dig in deep," said Beaton. "I'll be better prepared for the next game."
Newton also allowed opponent Johnny Haines opportunities but the Swindon man didn't do enough on his own throw to truly threaten.
Fleetwood man Newton warmed to the task and a 135 checkout sealed what in the end was a comfortable victory.
Colin Osborne is also through to the second round after securing a comfortable 3-0 victory over the Philippines' number one Lourence Ilagan, who had earlier beaten Jamie Lewis 4-3 in a preliminary round encounter.
