James Wade and Gary Anderson have booked their places in the World Championship semi-finals.
Wade, the fourth seed, got the action underway on Saturday afternoon against Mervyn King, his opponent kicking off with an authoritative 11-dart leg.
However, that was as good as it got for the veteran, who squandered opportunities in the opening sets and allowed Wade to cruise to a 5-0 win.
Anderson had to work harder to see off the challenge of Luke Humphries, the 19th seed taking a 1-0 lead and pegging Anderson back at 2-2.
Nevertheless, it was two-time world champion Anderson who held his nerve in the key moments, winning four of his five sets in a deciding leg to eventually prevail by a 5-2 scoreline.
Anderson will meet the winner of the match between Peter Wright and Callan Rydz, while Gerwyn Price or Michael Smith will go up against Wade in Sunday's last four.
