Luke Humphries has made it through to the World Grand Prix quarter-finals, along with James Wade, Gian van Veen and Niels Zonneveld.
World number two Humphries, who won the tournament in 2023 and was beaten by the eliminated Luke Littler in last year's final, was a comfortable 3-0 winner against Jermaine Wattimena in Leicester.
The Englishman will play the Netherlands' Zonneveld, who beat Gary Anderson 3-1, in the last eight.
Wade has won the World Grand Prix twice - in 2007 and 2010 - and kept his hopes of a third title intact with a 3-1 win against Stephen Bunting.
In a tournament where you have to start and finish each leg with a double, Wade took the first two sets and, despite losing the next, won the fourth to secure victory.
Van Veen, who was beaten by Littler in the PDC World Championship final in January, won the first set against Ryan Searle but then found himself 2-1 down.
He recovered to level before taking the decider to set up a quarter-final against Wade.
