Two-time champion Adrian Lewis and tournament favourite Michael van Gerwen set up a mouthwatering semi-final at the PDC World Cham­pionship with wins last night.

Lewis crushed James Wade 5-1 in an encounter which failed to match the drama of last year's semi-final.

Van Gerwen, meanwhile. beat Welshman Mark Webster 5-3 after coming through a mid-match wobble.

Lewis was rarely troubled by Wade, racing to a 3-0 lead before his opponent even got on the board. But Wade would only win one more leg as Stoke-based Lewis cruised through.

"I took my chances but it wasn't a great game," said Lewis. "The key thing was keeping concentration.

"I am looking forward to it [facing van Gerwen]," he said. "He's hitting big scores. I have been there and done it so let's see what he's got. Let the best man win."

Earlier van Gerwen had started superbly against Webster before limping over the line. The Dutchman was brilliant in the opening set, winning the first three legs with checkouts of 121, 124 and 139.

He cruised through the next two sets before Webster finally got on the board in the fourth, taking it 3-1 courtesy of a 102 checkout.

Van Gerwen swiftly reasserted his authority with a 180 and then a 144 shot to move 4-1 up. But, having played so brilliantly, his level dipped and Webster started to make inroads into his opponent's advantage.

He pulled it back to 4-3 before van Gerwen finally woke from his slumber to clinch a place in the last four. Despite the achievement, van Gerwen was not happy with his performance. "I didn't play well at all," he said. "I played well at the start but then I was over-confident. I lost my focus and my concentration.

"I am gutted about that, not happy.You don't do it on purpose but you know it's happening and it makes it even more difficult. I have something to work on now in the 24 hours leading up to my semi-final game, but I still fully believe I will be World Champion on January 1."
