St Helens darts ace Michael Smith
Smith, one of the favourites to lift his first major TV title, crashed to an 11-7 defeat at the hands of Dirk van Duijvenbode and Chizzy went down to Welshman and former world champion Gerwyn Price 11-8.
Dutchman Van Duijvenbode came flying out of the starting block against Bully Boy and soon established a commanding 4-0 advantage, which included a 170 check-out.
Smith rallied to move within one leg of his rival but fluffed a couple of darts to level at 5-5 while his finishing woes continued in the next session as Van Duijvenbode opened up a 9-5 lead.
This year’s PDC World Championship runner-up missed double 12 for a nine-darter in the 15th leg before reducing arrears to 9-7 but Van Duijvenbode held his nerve to progress into the last eight.
He will next face Gerwyn Price, who has an opportunity to advance beyond the quarter-finals for the first time after battling back from 6-4 down to overcome Chisnall 11-8.
The turning point came following Chizzy’s unsuccessful attempt at 76 - the Welsh wizard landing an 124 check-out on the bull and never looking back.
