Aspinall denied Ryan Meikle who has had a superb weekend his maiden PDC ranking semi-final in a tie which was full of nervy drama as 'The Asp' survived a match dart in the form of a 170 checkout.
The crowd started to get ramped up which frustrated Aspinall who had to recompose himself and pin double 16 to move through.
This in a tie that Meikle looked the favourite in after going 5-3 up but bounceouts proved to be the issue as well as Aspinall getting better pinning a 121 checkout to break and force that decider. He moves through with a 99 average and five 180's.

Next will be O'Connor who moved into his second ever European Tour semi-final after a 6-4 victory over Jose de Sousa in a tie which saw him seal a mammoth comeback in doing so.
O'Connor broke to start the tie at 3-2 down but couldn't consolidate and De Sousa pinned double 12 to move 4-2 ahead only for O'Connor to hit back and pin double 13 for 4-4.
It was three on the spin as he hit 64 to break followed by an 81 checkout to seal it and conclude the comeback.
