Adrian Lewis suffered one of the biggest shocks in the history of the World Championships, after being beaten in the first round by German qualifier Kevin Munch.
Seventh seed Lewis had never lost in the first round before in 12 years of playing in the event, but it was unlucky number 13 as he came up against Munch.
The two-time winner was unavailable for comment after being knocked out of the tournament, but later tweeted that he was 'gutted' by the result, and vowed to put it right this season.
German left-hander Munch had overcome Russia's Aleksandr Oreshkin in straight sets in the preliminary round to face the Jackpot.
He found seven of his eight 180s in seven legs that took him from a set down to the brink of victory, adding finishes of 158, 118 and 124 for good measure.
The 27-year-old from Bochum recently gave up his job as a landscape gardener to try and make a career in darts.
"I can't believe it," said Munch, who previously qualified for the World Championship six years ago. "It feels so amazing. I will realise what I've done tomorrow. I was so confident in that moment and not scared of him.
"I didn't realise the fans were so loud but I do now! I will relax and practice for the second round now.
"It's the biggest win in my career. I'm very proud "
