Van den Bergh 'dreaming' of Grand Slam glory after Clayton win
Van den Bergh spoke afterwards and admitted he is 'dreaming' of adding this title to his World Matchplay triumph earlier this year.
"So far it's going very well and I'm really proud," said Van den Bergh.
"I feel like I played a terrific game from the start until after the second break - I kept Jonny under pressure and I was phenomenal in parts.
"I felt that here and there I could be a little more focused, but I'm really happy to be in another quarter-final. I'm on a winning streak and I want to keep this going.
"I'm buzzing. I'm really happy - inside I'm having explosions of happiness. I'm dreaming about winning this and I hope I can make my dreams come true again."
