Former champion Rob Cross and Dave Chisnall have crashed out of the darts world championship as more seeds were scattered at Alexandra Palace.

Fifth seed Cross, the 2018 champion, lost 3-1 to Scott Williams while Ricky Evans survived a match dart against him to upset sixth seed Chisnall in an epic second-round clash on Monday night decided by a sudden death leg.

Evans walked to the oche in his own personalised festive shirt to the Shakin' Stevens hit Merry Christmas Everyone - and the Kettering ace again saved his best for the biggest tournament of the year.

Having beaten world No.6 Nathan Aspinall at Ally Pally 12 months ago, Evans held his nerve to win 3-2 after both players had missed match darts to set up a third round date with Welshman Robert Owen.

"I've played a world class darts player and it's nice to say I've won a game and played well. Normally it's poo," Evans told Sky Sports.

"What am I doing the other 11 months of the year?"

Almost unable to accept his status as a crowd favourite, Evans said: "I don't get this treatment in my household. Why are they cheering me on - 'Ricky Evans, Ricky Evans' - I don't understand it.

"I kept telling them to shut up. I'm trying to win a game here, but they were getting louder and louder. But thank you very much, you've made a fat guy very happy."

Chisnall took the first set in style and seemed on course to maintain his record of having not lost a first round match at the world championship since 2018.

But after Chisnall levelled at 2-2, Evans, throwing first in the sudden-death decider, responded to send the crowd wild.

Cross took the first set against fellow Englishman Williams - a surprise Ally Pally semi-finalist 12 months ago - but 'Voltage' was low on power after that.

Williams rolled off the next three sets as a gruelling evening session finished less than 20 minutes before midnight.

Seventh seed Jonny Clayton won a sudden-death leg in the deciding set to edge past Mickey Mansell and book his place in the third round.

The Welshman will meet 26th-seeded Daryl Gurney next after the Northern Irishman came from behind to beat Florian Hempel 3-2 in a pulsating affair.

Hempel's fellow German Ricardo Pietreczko produced a clinical finishing display - hitting 56 per cent of his doubles - to beat 28th seed Gian van Veen 3-1.

PDC Asian Tour leader Alexis Toylo lost 3-1 to Krzysztof Ratajski, 18th seed Josh Rock coasted to a 3-0 victory over Welsh debutant Rhys Griffin and former UK Open champion Andrew Gilding beat Martin Lukeman 3-1 to reach the third round for the first time.
