Luke Littler insisted he must block out the hostile reception from crowds after securing another Premier League triumph.
The 19-year-old world champion faced jeers throughout the evening on Merseyside but refused to let it affect his performance.
Littler overcame Luke Humphries 6-2 in the last eight before narrowly battling past Michael van Gerwen.
He then ruthlessly dispatched Jonny Clayton 6-1 in the final, though his rival continues to occupy the summit with a three-point advantage.

He's seemingly learning to adjust to the experience, however, and addressed his relationship with spectators after his win.
"Rotterdam was way louder than this tonight," he said.

Humphries finds himself in an increasingly precarious position, sitting sixth in the table and facing the genuine prospect of missing the play-offs entirely.
The defending champion, who lifted the trophy last May, has managed only seven match victories through 12 weeks and is yet to claim a single nightly win this season.
His struggles were evident against Littler, where despite posting a higher average of 99.39, his finishing proved costly. Humphries converted just 18 per cent of his doubles compared to Littler's 46 per cent.
The No 2 now trails Van Gerwen in fourth by five points with only four nights remaining to rescue his title defence.
