Rico Vonck, a 19-year-old from Holland, set up a third-round clash with compatriot Raymond van Barneveld at the PDC World Championship courtesy of a 4-2 victory against Canadian champion Brian Cyr.
And in another close encounter in the afternoon session, Terry Jenkins resisted a comeback from Steve Beaton.
The final set was a close one, and sixth seed Jenkins needed a 101 checkout to finally end the challenge of the 1996 Embassy world champion with a 4-3 success.
"I went 2-0 up but then the doubles just wouldn't go in for me," said Herefordshire's Jenkins, runner-up in the last televised tournament, the Skybet World Grand Prix in Dublin.
"I lost my way a bit and let it get to me, but I held my own in the end.
"I knew I had to play well because Steve has been coming back to his old form and his finishing is brilliant."
