Glen Durrant, Nathan Aspinall, Dave Chisnall and Jermaine Wattimena were all victorious in Dublin on Wednesday to complete the quarter-final line-up at the 2019 BoyleSports World Grand Prix.
Day Four of the double-start event saw the final four last 16 ties take place at the Citywest Convention Centre as three players won through to the quarter-finals for the first time.
Durrant and Wattimena will meet in Thursday's quarter-finals after the Lakeside Champion performed under pressure in a five-set thriller with Rob Cross and the Dutchman knocked out Peter Wright.
After a staccato start, the first ever meeting between former World Champion Cross and Lakeside Champion Durrant blossomed into one of the most memorable matches of the tournament so far this year.
The opening set's decider was won by debutant Durrant, before the second set saw Cross land finishes of 144 and 134 to level with a 3-0 scoreline.
With Durrant being outscored, he relied on missed finishing doubles from Cross to stay ahead in the third set before a 109 checkout saw him regain his one-set lead.Set four went to a deciding leg, but after Durrant took eight darts to get away, Cross landed a 138 checkout to keep his hopes alive at two-all in sets.
The deciding set began with both players hitting their stride as they exchanged 180s before Durrant found double 16 with his last dart in hand to go 1-0 up.
The third leg saw Cross miss three darts at double, before Durrant found double five to go within a leg of the match once again and this time he drove home the advantage, kicking off with a 152 and taking out 54 to bring the curtain down on a dramatic affair.
Meanwhile, Wattimena was left in tears after beating Wright 3-1 to reach his first individual televised quarter-final - following June's run to the World Cup semi-finals for the Netherlands.
UK Open champion Nathan Aspinall will face 2013 World Grand Prix finalist Dave Chisnall in the quarter-finals after Dublin debutant Aspinall twice came from behind to claim a 3-2 win over Danny Noppert.
It was a simpler passage into the last eight for Chisnall, who won in straight sets against Stephen Bunting.
Thursday's quarter-finals will begin with the tie between Ian White and Chris Dobey, while reigning champion Michael van Gerwen continues his bid to win a fifth Dublin title against Mervyn King in a repeat of the 2012 decider.
