Luke Littler came close to reaching the Premier League final on his debut, but his night was ruined by the Welsh whistler.
The Tungsten teenager missed a double 15 by a millimeter in the final leg shootout after losing 6-5 to Michael Smith in the semi-final in Cardiff.
But Bully Boy was the target of audible whistles every time he threw for a crucial double on night one.
Angry Smith, 33, made his feelings known to the fools after beating the Boy Wonder to reach the £10,000 final, defeating home favorite Gerwyn Price 6-2.
The former world champion made an aggressive neck-slashing gesture towards the audience and told them to be quiet.
PDC security attempted to track down the person making the disturbing noise inside the Utilita Arena, which continued into the final match.
Littler, a 17-year-old rookie, averaged 105.31 points in the loss, showing once again that he can match the Arrows’ nobility at the highest level.
Early in the evening, Littler’s first competitive appearance was overshadowed by the venue’s noisy fans.
Current world champion and world number one Luke Humphries was looking to make it 2-2 after throwing a double eight in leg four.
However, as I was going through the motions, I was distracted by the sound of a whistle and turned around to see if I could identify the nuisance punter.
Littler won the throw, advanced 3-1, and never looked back in his second match since the world finals.
The same thing happened in the final leg, with Humphries trying to stay but missing the mark, before Littler won 6-2.
Darts Stars don’t have a problem with crowds singing and making noise, but the whistles often get in their heads and become a distraction.
Smith, who defeated Michael van Gerwen 6-5 in the quarter-finals, celebrated his win by wearing a £700 Valentino sweatshirt.
The world No.3 said: “The easiest fight was against Van Gerwen when there was a crowd. It was okay.
“There were some whistles in Luke’s case. It happened against Gaethje. I don’t blame them because they want to root for their hometown guy. That’s why they’re here. You expects it.
“I feel sorry for everyone because I had to win. Last week, I threw too slow and got a warning from my wife.
“All I did tonight was my throw. I was lucky enough to kick off in the 180s in the final. I just focused on my darts.”
The £1 million 17-week Premier League roadshow is set to move to Berlin next Thursday.
