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."
Aiming to improve a disappointing record at the World Championship, world No.6 Wes Newton began his campaign with a 3-0 rout of Swindon debutant Johnny Haines.
Newton, known as 'The Warrior', edged a scrappy opening set before winning six of the last seven legs, sealing victory with a 135 finish, to book a second round duel with either Kim Huybrechts or Scott Rand.
Former champion Steve Beaton set up a second-round showdown with world number three James Wade in the opening match of the night after whitewashing Australian qualifier Kyle Anderson.
Beaton, world champion back in 1996, scored heavily throughout but missed a combined total of 23 darts at doubles before progressing.
Speaking afterwards, Beaton said: "It was a tough game. People don't understand the pressure you're under when you get here. I had to dig in deep. I'll be better prepared for the next game (against Wade). I'll be up for it."
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.
