World No.1 Michael Van Gerwen has crashed out of the PDC World Championship with a 5-0 quarter-final loss to Dave Chisnall.
A superb display from Chisnall saw him average 107.34 as he whitewashed three-time champion Van Gerwen and moved into the semi-finals of the competition for the first time on Friday.
Chisnall's last-four opponent will be two-time winner Gary Anderson, who earlier beat Dirk Van Duijvenbode 5-1.
Anderson, the champion in 2015 and 2016, lost the opening set before surging to a 5-1 victory, averaging 101.07.
"That was good," Anderson told Sky Sports.
"First set Dirk went off like he did, and I played actually alright - I went 'here we go'. But I stuck in."
Asked if we were seeing the Anderson of 2015 and 2016, the 50-year-old said: "Not quite yet. It's getting there.
"The 140s are coming good now. Still a few mistakes, but happy."
The other match of the afternoon session saw Stephen Bunting defeat Krzysztof Ratajski 5-3 to move into the last four of the competition for the first time.
Bunting's opponent in the last four will be either Gerwyn Price or Daryl Gurney.
