Dave Chisnall lost out in a thriller to Raymond van Barneveld in Cardiff on Thursday night.
The Morecambe ace, second in the table, led for most of the Betway Premier League contest at the Motorpoint Arena only for the Dutch great to produce some fine finishing to win 7-5.
Chisnall led 2-0 before finishes of 96, 90 - on the bull - and 76 saw reigning champion van Barneveld reduce the gap to 4-3 before he levelled by taking out double six to break in leg eight.
Chisnall immediately broke back as he traded 180s with the Dutchman before posting double eight to lead 5-4, but a brilliant 132 bullseye finish saw van Barneveld square the game.
He then finished 85 to win the 11th leg to lead for the first time, before Chisnall - for a second successive leg - traded 180s with his rival in the decider only to miss two darts to claim a draw, as another 90 finish on the bull gave van Barneveld both points.
The result saw van Barneveld win for the third successive match while Chisnall lost for the second straight week.
Van Barneveld said: “It was an unreal win.
“The 132 was amazing and the three bull finishes were extremely important.
“I’m playing extremely well and feeling confident, and I’m happy and enjoying myself - because I’m winning.
“The crowds are behind me and I still believe that I can make the top four.”
Elsehwere, Michael van Gerwen secured his place in the play-offs with a whitewash of James Wade before the world number one was edged out 7-5 by Gary Anderson in his second match of the night.
Anderson’s win saw him bounce back from a disappointing defeat earlier in the night - where he went down 7-1 to Stephen Bunting.
Phil Taylor and Adrian Lewis also shared the spoils in a 6-6 draw.
The Premier League moves onto the Barclaycard Arena in Birmingham next Thursday when Chisnall takes on Lewis in the night’s opening match.
