DAVE CHISNALL eased through to the quarter-finals of the William Hill World Championship with a straight sets victory over Jamie Lewis.
Chisnall won 4-0 for the second consecutive match as he dumped out Welshman Lewis, who reached the semi-finals at Alexandra Palace 12 months ago.
A 118 checkout helped Lewis move two legs clear in the first set but Chisnall overturned the deficit before winning the second set 3-1.
Chisnall defied a second 118 finish from his opponent to edge set three in a deciding leg, before taking the fourth set 3-1.
Chisnall has now won 11 consecutive sets since going 2-0 behind against Josh Payne in round two. He will take on Gary Anderson on Saturday.
