Dave Chisnall thrashed Robert Thornton 11-2 to set up a BetVictor World Matchplay quarter-final against Michael van Gerwen.
The Morecambe ace raced to victory at the Winter Gardens in Blackpool on Tuesday to reach the last eight for the fourth successive year.
Scotland’s Thornton had won his first ever game at the World Matchplay in his seventh appearance when he defeated Josh Payne on Saturday, but never recovered from seeing Chisnall open up an early 7-1 lead, with a 132 bull finish the stand-out moment of some fine darts.
Thornton took out 130 on the bull to respond briefly in leg nine, but Chisnall landed a 180 in the next, two double top finishes to move 10-2 up and double 10 to complete a big win.
“It went well tonight and the week is looking good so far,” said Chisnall, who beat Benito van de Pas in round one.
“Robert missed a few doubles for big checkouts and I took my doubles and punished him.
“The scoreline could have been closer but I played well enough to win the game and I think I deserved it.
“This is the second biggest competition on the calendar and I’m hoping to do well.
“I’m playing steady darts but I want to past the quarter-finals now and I’ll be trying my hardest on Thursday.”
Chisnall and van Gerwen meet in the last eight on Thursday after the reigning champion beat Kyle Anderson 11-3.
