Adrian Lewis started his quest for a third PDC World Darts Championship title with a straightforward victory over Magnus Caris and Mervyn King was in tears after a thrilling tie-break win over Steve West on Monday.
Lewis was beaten by Gary Anderson in the 2016 final and is aiming to go one better this time around at Alexandra Palace.
The fifth seed had no trouble in reaching round two, storming to a 3-0 win over Swede Caris after throwing five 180s and averaging 93.25 on the fifth night of the tournament.
Lewis, nicknamed 'Jackpot', had never lost in the first round in his 11 previous World Championship appearances and Caris never looked like ending that record.
There was plenty of drama in the previous match, with 22nd seed King coming from two sets down to dump West out in a gripping contest.
Two-time BDO World Championship runner-up King looked set to be heading for an early exit, but rallied from the brink of defeat and won a deciding final set 6-4.
Corey Cadby beat Qiang Sun in a preliminary contest in the first match of the evening, only to go down 3-1 to Joe Cullen later on.
