Michael Smith secured a hat-trick of Premier League Darts nightly wins by defeating Michael van Gerwen, Jonny Clayton and Gerwyn Price en route to more stunning success in Sheffield.
Price could have guaranteed top spot with victory in the Night 15 showpiece, but the St Helens star cut the Welshman's lead at the summit to just three points after claiming the spoils in the Steel City.

Smith began his campaign with a 6-4 win over reigning champion Van Gerwen, converting a stunning 130 checkout on the bull to defeat the Dutchman for a second week in succession.
The world No 1 continued his charge to defeat Clayton in a repeat of last week's decider, averaging almost 108 and sealing the deal with a superb 11-darter.
Smith then capped off a terrific night of action by claiming the £10,000 winner's bonus, extending his winning Premier League run to nine matches in the process.
"Three in a row, it took me 15 weeks to win one night last year and now I've won four," reflected Smith, who has leapfrogged Van Gerwen into second spot after his fourth nightly win overall. "I am still in with a chance of finishing top.
"Me and Gez spoke about it backstage before the match, if it's me and him in the final next week he finishes top. Hopefully I can be top.
"I know you get nothing out of finishing top but it is the prestige. I have qualified last week and I could have just laid down and let anyone beat me. But I still need to go to The O2 playing well and winning."
Price - who was victorious in Sheffield 12 months ago - retained top spot after storming through to his eighth nightly final of 2023 with 6-2 wins over Nathan Aspinall and Chris Dobey.
In the evening's other quarter-finals, Clayton moved two points clear of Aspinall ahead of their decisive Night 16 showdown, courtesy of a battling 6-4 victory against Dimitri Van den Bergh.
The 2021 champion conjured up a spectacular 170 checkout midway through the tie, and registered his sixth ton-plus average of the campaign to see off the Belgian.
'The Ferret' is in a straight shootout with Aspinall for the final spot, with the pair going head-to-head in the quarter-final next week in Aberdeen.
Victory will assure the Welshman another appearance at The O2 while even if Aspinall wins the quarter-final he also has to win his semi-final.
"It's massive," Clayton said. "All the pressure is on Nathan next week. He has to win, the ball is in my court because if I win I am through. I am going to try and relax and play my game.
"I was shaking like hell up there. It's two points that are going to be massive."
Meanwhile, Dobey cemented sixth spot in the table with an impressive 6-4 success against Peter Wright, crashing in six 180s and reeling off four straight legs from 4-2 down to advance.
