Seventh seed Peter 'Snakebite' Wright survived a major scare to beat Noel Malicdem 3-2 in a sudden-death shootout at the PDC World Championship.
The Scottish 2014 runner-up and 2017 semi-finalist won 6-5 in the fifth set of a dramatic second-round match.
Englishman Nathan Aspinall and Germans Max Hopp and Nico Kurz also made it through to the third round.
On Saturday night, Fallon Sherrock - the first woman to beat a man at the tournament - faces Mensur Suljovic.
Wright, wearing a green elf-style shirt, looked set to deliver a straightforward victory as he cruised to the first set.
But his opponent, from the Philippines, rallied and at one stage had a dart at bullseye to triumph.
He missed to leave an opening for Wright, who hit 162 followed by a 140 checkout to save the match, before edging to victory in a tense sudden-death leg,
Wright plays Keegan Brown or Seigo Asada next.
