Clayton first of all came through a tough tie with Ian White.
He saw him off in a 6-3 win with a 97 average as two of the most consistent players on the Pro Tour battled it out.
He will face Adrian Lewis who once again wasn’t really troubled as he eased past Vincent van der Voort in a 6-2 win.
Keegan Brown was probably the most impressive as he smashed through Andy Boulton in a 6-1 win with a 102 average.
He will face Raymond van Barneveld who continues to make progress. ‘Barney’ showed flashes of brilliance against Jan Dekker and will now hope to go all the way.
