Luke Littler appeared to break a deal he made earlier this week where he promised to cheekily troll Ricardo Pietreczko if he beat Luke Humphries in the Premier League.
The teenager is bidding to win his first Premier League night and faced a tough task in the opening match in Belfast.
Humphries had won the three previous nights and was looking to become the first player in the history of the competition to win four in a row.
Much like the other matches between them both, the players immediately found a high standard of darts with Littler landing some important darts to stay in control of the match.

And he held his nerve when it mattered most as the match went to a deciding leg as he landed his favoured double-10 to beat Humphries.
Littler celebrated wildly as he jumped around the stage before sharing a warm embrace with Humphries.
He shook hands with the officials before returning to his table, puffing out his cheeks to express his relief.
But Littler didn't appear to do the 'finger wag' celebration he promised he would do in reference to his tetchy match against Pietreczko at the Belgian Darts Open earlier this month.
Pietreczko felt Littler disrespected him during their match and called the teenager 'arrogant'.
The teenager appeared on the Happy Hour podcast earlier this week and spoke about the incident.
Host Jack Dean cheekily asked Littler to repeat the winger fag he received from Pietreczko as part of his celebration if he ended up being Humphries.
Littler accepted the challenge and shook hands with the podcast host, but didn't appear to make the gesture after the match against Humphries.

Sky Sports cameras turned away from Littler while he was standing at his table as the focus turned to the next match.
It's not the only deal Littler appeared to break as he revealed on the podcast he was also asked to do a 'little 'w' for my next win'.
The win over Humphries gives Littler a chance to return to the top four in the Premier League table after a disappointing result last week.
