Phil Taylor overcame Kevin Painter in the second round of the PDC World Championship despite an unconvincing display on day 10 at the Alexandra Palace.
The 16-time world champion completed a 4-1 win despite an inconsistent performance to set up a last-16 meeting with either Mervyn King or Jelle Klaasen.
Taylor lost the first set and, despite his struggles with scoring and on the doubles, he advanced with a 92.91 average.
Two-time winner Adrian Lewis produced another clinical display to beat Andrew Gilding in the first game of the evening session.
World number five Lewis eased to a straight-sets victory over Jan Dekker in the first round and also made light work of seeing off Gilding 4-0, chalking up eight 180s and losing only two legs in a one-sided encounter.
Peter Wright produced an ominous performance to also go through to the last 16 with a straight-sets triumph over Ronny Huybrechts.
World number four Wright hit a 180 in the opening leg and never looked back, reeling off eight legs in a row to progress at a canter.
Mark Webster had earlier ruthlessly ended Terry Jenkins' participation by coasting to a 4-0 victory over the 2011 semi-finalist.
Jenkins took just for legs off the impressive Webster, who will now face Alexandra Palace debutant Alan Norris after he got the better of Joe Murnan 4-1.
Mensur Suljovic came out on top in a thriller against David Pallett, with both players missing doubles for a nine-dart finish before the Austrian hit the bull to seal a tense 4-3 victory.
