Then 23-year-old Michael Smith claimed the biggest win of his career in incredible fashion, knocking reigning champion Phil Taylor out of the 2013/14 World Championship in the second round.

Smith capitalised on errors from 16-time champion Taylor, producing 11 and 13-dart legs in the deciding set before taking out a 128 finish on the bullseye to secure a memorable 4-3 victory.

4. South African rookie's incredible comeback KO's Manley

South Africa's Wynand Havenga made a name for himself at the 2006/07 World Championship by knocking out three-time runner-up Peter Manley in round two.

On the back of his dream debut win over Steve Maish, one-hit wonder Havenga found himself 3-0 down to Manley before a sensational comeback saw him win 4-3 in only his second TV appearance.

3. Lewis blows away Wright with career-best performance

Jamie Lewis produced the performance of his career to blow away number two seed Peter Wright 4-1 in the second round of the 2018 World Championship.

With 11 titles to his name in 2017, many fans and pundits were tipping Wright to land a first World Championship title ahead of the event, but Lewis tore up the form book with a spectacular 107.27 average.

The Welshman had only qualified for the tournament following a third-place play-off at the PDPA qualifier, but made up for a nightmare year on the circuit by dropping just two sets en route to the semi-finals, where he became Phil Taylor's last victim in professional darts.

2. Ruthless Richardson dumps out Barney

Unknown bricklayer James Richardson shocked five-time World Champion Raymond van Barneveld with a 3-0 demolition in the first round of the 2011/12 World Championship.

Ranked 85th in the world, inspired debutant Richardson romped to a convincing victory to inflict a first ever opening round defeat on Van Barneveld.

1. Shepherd shocks the world

The story of Kirk Shepherd's fairytale run to the final of the 2007/08 World Championship remains one of the most heralded in darts history.

A 21-year-old sheet metal worker from Ramsgate, qualifier Shepherd took to the oche in his first round game against Terry Jenkins with few people giving him a chance of progressing to the second round.

But after Jenkins missed seven match darts, Shepherd battled his way to a surprise 3-2 victory, and went on to survive more match darts to edge past Mick McGowan and Peter Manley, while also defeating Barrie Bates to reach the semi-finals.

There, he stunned Phil Taylor's conqueror Wayne Mardle to become the highest priced outsider in World Championship history to reach the final as a pre-tournament 1000/1 shot.

John Part ended his World Championship dreams in the final with a 7-2 success, bringing the curtain down on an incredible tournament.

The 2019/2020 William Hill World Darts Championship will be held from December 13-January 1 at Alexandra Palace in London.
