Adrian Lewis, tipped by many as a future world champion, booked his place in the last 16 Ladbrokes.com PDC World Championship in London by seeing off Dutchman Vincent van der Voort 4-2 in a high-quality encounter on Wednesday.
Lewis threw a 10-darter to come from behind to take the first set and Van der Voort also led in the second before falling 2-0 behind.
Van der Voort took the third and the pair then again traded sets for Lewis to lead 3-2.
The scores were locked at 2-2 in the sixth set but Lewis fired a 180 - his seventh of the match - to claim a decisive advantage.
Former world champion John Part eased through with a 4-1 win over German number one Mensur Suljovic.
James Wade also made progress, holding off a spirited comeback from Steve Beaton to win 4-3.
