World champion Adrian Lewis has crashed out of the Grand Slam of Darts after he was defeated 5-2 by John Part.
Both players performed well below par, but it was the Canadian who held his nerve to move on to a winner-takes-all showdown with Tony O'Shea.
O'Shea missed two match darts as he fell to a 5-4 defeat to Gary Anderson, which resulted in the Scot being the first man through to the second round.
Christian Kist won the battle of the Dutch world champions with a 5-4 victory over Raymond van Barneveld, while Mark Walsh edged out local favourite Wayne Jones by the same scoreline.
Wes Newton beat Wesley Harms 5-2 to almost seal his place in the last 16 and Terry Jenkins triumphed over Welshman Martin Phillips to keep his hopes alive in the tournament.
Paul Nicholson recorded an emphatic 5-0 whitewash win over Barrie Bates, while Andy Hamilton clinically saw off Brendan Dolan 5-1.
