Josh Rock managed a 104.02 average in his 16-11 win over Gerwyn Price to set up a semi-final against reigning world champion Luke Littler at the World Matchplay in Blackpool.
Antrim native Rock, who had beaten Michael van Gerwen on Wednesday, managed to get the better of 2021 world champion Price in the fourth quarter-final to be played at the Winter Gardens.
"I'm on cloud nine at the minute," Rock said.
"I can’t wait to finally play Luke on the big stage. The darting world will be watching that game tomorrow.
"Luke is one of my close friends behind the scenes. Hopefully we both turn up, but I’m sure it will be a cracking game.
"I’m just so relieved to be in the semi-finals. Gezzy played really well tonight too, he never gave up, but wow – what a game."
Earlier, Littler produced an impressive 11-dart leg to seal a 16-14 victory over Andrew Gilding in their quarter-final.
The world champion never went behind and produced a 103.91 average.
Littler had a five-leg advantage at one point in the contest, during which he produced 18 maximums.
However, Gilding set up a tense finish - with a 160 finish the highlight of a three-leg streak by the former UK Open champion.
While Littler and Rock will now meet for a place in the final, Saturday's other best-of-33 leg semi-final sees James Wade face Jonny Clayton.
