Alexandra Palace debutant Nathan Aspinall says he is getting "better and better" after booking his place in the PDC World Darts Championship semi-finals.

The 27-year-old from Stockport beat Brendan Dolan 5-1 on Saturday afternoon to become the first man in the last four, with two-time winner Gary Anderson joining him later.

"It went well, I played really well today, I felt so confident and relaxed, no nerves whatsoever. Everything was flowing and happy days, in the semi-final," Aspinall told Tungsten Tales.

"I'm the first one through, I'm getting better and better. Whoever I play, it'll be a cracking game, one of us is going to be in the final."

Anderson did well to see off the heavy-scoring Dave Chisnall with relative ease.

He led 3-1 and 4-2 before booking a fourth semis appearance with a 5-2 win.
