Jonny Clayton ended Luke Littler's challenge at the World Series of Darts Finals in Amsterdam, putting an end to Littler's hopes of a calendar year clean sweep. Clayton will now face fellow Welshman Gerwyn Price in Sunday's second semi-final.
The other semi-final will see Ross Smith take on Gian van Veen.
The defeat for Littler means his bid for a major clean sweep in the calendar year is over.
