Brendan Dolan is through to the PDC World Championship quarter-finals for the first time after a 4-1 victory over Benito van de Pas in London.
The 45-year-old from Fermanagh lost just two legs in winning the opening three sets on Friday.
Dutchman Van de Pas showed glimpses of form in pulling a set back before Dolan took the fifth set 3-2 to secure his progress with a 90.04 average.
Dolan faces England's Nathan Aspinall in a last-eight game on Saturday.
Surprise wins over Joe Cullen and Mervyn King helped the 45th-ranked Dolan to the last 16 stage at Alexandra Palace.
An out-of-form Van de Pas struggled to keep pace with Dolan as the Northern Irishman won the opening two sets 3-1 and then 3-0 in the third.
However, Van de Pas clinched a 3-2 win in the fourth set and the 25-year-old, who is ranked 30th, moved 2-1 up in the next set.
The comeback was on but Dolan hit back to take the next two legs and wrap up a victory which included four 180s and a 148 checkout.
Dolan is now guaranteed at least £50,000 prize money and he will take on World Championship debutant Aspinall, who fought back to beat Devon Petersen 4-3 earlier on Friday.
