NATHAN Aspinall ended Gerwyn Price's reign as BoyleSports Grand Slam of Darts champion in a second round classic in Coventry on Saturday.

Price had been aiming to lift the Eric Bristow Trophy for a third successive year.

However, Aspinall regained his composure to win the next two legs, and when Price missed two darts at double four to take the game into a deciding leg, he took out 92 on the bull to claim a memorable win.

"It's a massive win for me," said Aspinall.

"He brings the best out of me and I knew I had to score well tonight and finish well.

"I missed six darts to go 8-7 up and to not let that affect me, and to come back the way I did to win the last three legs I'm very happy and proud of myself."

After Price had taken out 110 to level in leg four, Aspinall took command with four straight legs and finished 94 for a 7-3 cushion.

The Welshman dug deep in his quest to retain the title, finishing 70, 87, 105 and 75 in his five-leg burst to move ahead for the first time since the opening leg.

However, it was Aspinall who had the final say as he moved through to set up a quarter-final tie with World Matchplay champion Dimitri Van den Bergh on Sunday evening.

"I owe him one because he's won our last two games on TV, in the World Matchplay and in the Group Stage earlier this week," added Aspinall.

"He's a different player now than he was six months ago, and the last two times I've played him I struggled to get any kind of adrenaline going. He's very tough for me to play against."

Michael van Gerwen powered into the quarter-finals with a 10-2 defeat of Gary Anderson to continue his bid for a fourth Grand Slam title.

The world number one's return to top form continued as he averaged 102 and defied six 180s from long-standing rival Anderson to clinically set up a quarter-final against Simon Whitlock on Sunday evening.

Going into Sunday's quarter-finals, Van Gerwen is now the 5/4 tournament favourite with sponsors BoyleSports to claim the title on Tuesday evening.
