Darts commentator Wayne Mardle sarcastically mocked Luke Littler for his "rubbish" throw that wrecked a chance at a nine-darter against Luke Humphries with the crowd also left disappointed.
Matches between Humphries and Littler have been gripping ever since the two met in the World Championship final.
Littler has got the better of Humphries on two occasions since then, including in last week's Darts Premier League season-opener in Cardiff.
It was a much tighter affair this time round though with Humphries on top of his game.

That was on show in the sixth leg with Humphries already a break of throw up as both players started with 180s.
The world No 1 failed to give himself a chance of a nine-darter after missing the triple-20 on his fifth throw.
But Littler then stepped up and gave himself a shot at his second nine-darter of the year after hitting two more triple-20s along with a triple-19 to leave 144.
Humphries piled on the pressure himself though on his next visit with three more brilliant darts to leave himself a chance of a 10-dart leg.
However, Littler ended his run of six-perfect darts on a whimper with a wayward shot landing on five.
The crowd jeered Wayne Mardle then jokingly remarked on commentary: "That is absolutely rubbish."
It proved costly too as Humphries was able to wrap up the leg on his next visit to take a commanding 4-2 lead.
The teenage darts sensation soon levelled up the match though by taking the next two legs.

That gave Littler the advantage as he held the throw for the deciding leg with both players clearly showing signs of nerves when it mattered most.
Humphries left himself with 140, but missed the second triple-20 he needed to give himself a chance of a finish.
Littler left his favoured double-10 and needed just one attempt to wrap up the match and reach his first Premier League final.
Humphries showed his class by applauding Littler on stage before the two embraced.
