Fans watching Luke Littler's clash against Nathan Aspinall were left stunned after spotting what the 17-year-old did in the first set.
On Wednesday night, the eight remaining players in the 2025 PDC World Darts Championship battled for a semi-final spot at the Alexandra Palace, London.
In the afternoon session, Chris Dobey and Michael van Gerwen sealed their place in the next round after beating Gerwyn Price and Callan Rydz respectively.
Stephen Bunting then kicked off the evening session with a 5-2 win over Peter Wright before tournament favourite Littler went up against Aspinall.

He added: "They've [the crowd] been good for me tonight. They've also been good to Stephen.
