Double-defending champion Gary Anderson and Adrian Lewis romped into the third round of the PDC World Darts Championship, but former runner-up Simon Whitlock was stunned by Darren Webster.
Lewis outclassed Joe Cullen, who had won his first match in this tournament at the seventh attempt in the previous round against Corey Cadby, and eased to a 4-0 victory.
The two-time world champion was too good, however, with Lewis racking up an impressive three-dart average of 102.65 and registering five 180s to set up a potential meeting with Raymond van Barneveld after Christmas.
Anderson was another whitewash winner, beating Andrew Gilding at Alexandra Palace.
Gilding was impressive when looking for doubles, hitting 80 per cent of his checkouts, but they came few and far between as the champion moved through the gears.
Whitlock was unceremoniously dumped out by a brilliant Webster, who had a checkout percentage of 60 and averaged 104.64 in a surprise straight-set victory over the 2010 runner-up from Australia.
Michael Smith, the 11th seed, came up with 14 180s as he beat Mervyn King in a seven-leg thriller before Benito van de Pas ousted Terry Jenkins in another afternoon contest which ended 4-3, while Ian White ousted Jonny Clayton.
