Raymond van Barneveld will meet James Wade in the semi-finals of the SkyBet World Grand Prix after a thrilling victory over Adrian Lewis in Dublin.
The Dutchman edged out Lewis 4-3 in a thrilling match to stay in the hunt for the title, the world champion prevailing in the deciding last leg.
'It was an amazing match,' said van Barneveld. 'Adrian was fantastic and I had a feeling it would be a great game - he kept coming back at me and I'm so relieved to get through.'
Wade, July's World Matchplay champion, booked his place in the last four with a 4-0 whitewash of 2004 champion Colin Lloyd.
The other semi-final will see John Part face Terry Jenkins. Part came from two sets down to see off Adrian Gray, while Jenkins held off the challenge of Mark Dudbridge with a 4-1 triumph.
