Aspinall watched on as Smith spurned eight chances to claim a point; this allowed the former UK Open champion to claim a brilliant win.
"Maybe a draw would have been a fair result, but I'm happy to get the win and I'll take it," said Aspinall. "I feel like I've nicked a point from him but I've been in that position many times.
"It's probably the game I've enjoyed most during the Premier League this season. It was a brilliant game to be involved in - we bring the best out of each other and it was another great game. He threw everything at me but I dug deep.
"I felt for him at the end when he missed those doubles, but it shows that with or without a crowd, you still feel the pressure. I'm loving it though and I'll take confidence from tonight."
