Brendan Dolan smashed his way into the last 32 of the World Darts Championship with a stunning 3-0 win over Joe Cullen at Alexandra Palace.
The Fermanagh man dropped just one leg while averaging 92.72 against 'Rock Star' Cullen, who stood 31 places higher in the PDC's order of merit.
The History Maker will face either Holland's Jan Dekker or England's Mervyn King on Sunday.
"I went out to do my best," the world number 45 told RTÉ Sport.
"I improved on my finishing but I still believe there is more scoring power in the tank. Hopefully I'm saving it for the next round.
"I've been practicing a lot more than I have before.
"I think my timing was better."
The afternoon session also saw wins for Kim Huybrechts, Noel Malicdem and Nathan Aspinall.
Limerick's William O'Connor also moved into the third round following his win in a five-set thriller with James Wilson at Ally Pally.
In what was one of the best displays of his career, Ireland’s the joiner from Cappamore came from behind to win 3-2 against world number 26 James Wilson in the second round in London.
World number nine James Wade survived a major scare as he twice battled back from a set down to overcome Japanese qualifier Seigo Asada.
Wade, who won the European Championship in October, was given a stern test by the Asian Tour number two player and appeared to be feeling the pressure as he behaved demonstratively on stage, including shouting in the direction of his opponent having levelled at 1-1.
He eventually progressed 3-2 and will face Jelle Klaasen or Keegan Brown in the next round.
Wade said he "wanted to hurt" his opponent with his aggressive behaviour.
"I dug in deep there. It's a magnificent feeling. I could have easily lost that. I've done it for my son, for my country, so it's good," he told Sky Sports.
"I kept giving it to him, I wanted to hurt him, I wanted to really hurt him in his face.
"It wasn't a great game but I wanted to hurt him and I wanted to progress. That's for my son, and also for the UK."
Former player Wayne Mardle, working as a pundit, described Wade's behaviour as "thuggish" and said there was no place in darts for it.
"Does he mean he wanted to punch him in his face? What does he mean? I'm absolutely lost for words," Mardle told Sky Sports.
"That's just not on. The intimidation, overly aggressive, I hope he wakes up in the morning and thinks, 'I've made a mistake there'.
"He can't think that's right and no-one watching it can think it's right. That's thuggish behaviour, there's no place in darts for that."
