Phil Taylor has been sent crashing out of the PDC World Championship following a shock 4-1 defeat to Dave Chisnall at Alexandra Palace.
The 15-time world champion was distinctly out-of-sorts against Chisnall, the 2010 Lakeside runner-up averaging 99 to set up a third-round meeting with Andy Hamilton.
Chisnall becomes only the seventh man to knock Taylor out of the World Championship and ensured the Power failed to reach the last 16 of the competition for the first time in his stellar career.
'Chizzy' flew out of the traps, breaking Taylor early and clinching the first set on double eight to send an immediate warning of his intentions.
Both players averaged almost 100 in the early stages, however Chisnall was still prone to the odd stray dart, none more so than in the deciding leg of the third set when the St Helens thrower missed 19 - and as a result the chance of a dart at a 2-0 lead - and Taylor moved in to level matters on double eight.
Taylor broke Chisnall at the start of the third set, however the response from his opponent was stunning - he broke and then took out 119 to edge ahead.
The 31-year-old was a whisker away from wiping out 144 to wrap up the set, but despite Taylor levelling, Chisnall found double four with Taylor lurking to edge 2-1 up.
Taylor was enduring a night to forget on the doubles, in particular double top, and his woes continued when Chisnall fired in a 180 and backed it up with one dart at tops to move two sets clear.
The heat was really getting to Taylor now and a two-dart 67 finish saw Chisnall hold throw at the start of the fifth set. When Taylor missed two darts at tops in the fourth leg, Chisnall hit double six to seal a famous win.
"I don't know how I did that," he told Sky Sports HD2 afterwards.
"I threw well in the game but started getting a little bit nervous towards the end. On double 12 I just pulled it, but he gave me another shot and I took it."
Asked just when he thought he could get the better of Taylor, Chisnall added: "When it started. I always thought I could beat anybody if I play my game and hit my doubles.
"I'd never played him on the big stage, but where else would you want to play him?
"I'm just glad to get through. I thought I could beat him when I came into the Championship.
"On television I've not played my best darts, but I played alright there."
Kim Huybrechts also caused something of a shock in the opening match of the evening, knocking out James Richardson, the conqueror of five-times winner Raymond van Barneveld in the first round.
Huybrechts won the first set but Richardson hit a 140 checkout to take the second. The Belgian edged a narrow third set before whitewashing his opponent in the fourth, twice winning legs against the throw.
Both hit maximums in the fifth leg of the fifth set but it was Huybrechts who took it and the match to set up a last 16 meeting with Paul Nicholson.
The final contest on Tuesday saw Nicholson cruise through to the last 16, dropping just three legs as he quickly whitewashed Alan Tabern 4-0.
'The Asset' took the first six legs on the spin, hitting a 106 finish in the fifth. Tabern did finally get on the scoreboard at the start of the third set, then landed double eight to send it into a deciding leg.
However Nicholson came out on top to go 3-0 ahead and although 'The Saint' managed a 103 finish in the next set, it was only a case of delaying the inevitable.
Double 16 booked the Newcastle-born 32-year-old a place in the third round in a section of the draw that has been blown wide open by Taylor's early departure.
