Derry's Daryl Gurney fell agonisingly short in his quest to reach the semi-finals of the William Hill World Darts Championships on Friday night.
Gurney had his chances in both the fifth and sixth sets against Gerwyn Price at Alexandra Palace but some missed doubles ultimately proved to be very costly.
He came from 4-2 down to force a sudden death leg but despite having the first chance to take the match, he didn't leave himself a shot and the Welshman showed bottle to advance.
"I bombed a couple of sets where I missed loads of doubles. I was very lucky," admitted Price.
"At 4-2 up I had it in the bag but at four all I had to pull it out of the bag. I was up against it. I've certainly learned a big lesson tonight. I shouldn't be complacent when I am 4-2 up.
"It must have been nerve-wracking for my wife and family to watch. Maybe I wanted it too much but I'm still in the tournament and I'm going to give it my all."
Price will now face Stephen Bunting, who defeated Krzysztof Ratajski 5-3 to move into the semis of the competition for the first time.
Dave Chisnall then sent Michael Van Gerwen crashing out with a shock 5-0 victory over the world number one.
A superb display from Chisnall at Alexandra Palace saw him average 107.34 and hit 14 180s as he whitewashed three-time champion Van Gerwen and moved into the semi-finals of the competition for the first time.
The emphatic win by world number eight Chisnall - who almost registered a nine-dart leg, only missing a double 12 - ended a run of 27 matches without a victory over Van Gerwen.
The 40-year-old Englishman told Sky Sports: "I'm so proud. I've been practising well, I've been playing well I'd say for the last three, four weeks. I have put the effort in. I changed my points to a little bit smaller.
"I was confident against Dimitri (Van Den Burgh in the previous round) and this morning when I woke up I was confident again, just sitting in my hotel room watching the TV.
"I want it (the world title) more than anybody else does. I know my own ability, I know I'm playing well. I can win this."
Chisnall's last-four opponent will be two-time winner Gary Anderson.
Earlier in the day, the Scot made it through to the last-four after coming from behind to beat Dirk Van Duijvenbode.
Anderson, the champion in 2015 and 2016, lost the opening set before surging to a 5-1 victory, averaging 101.07.
Anderson told Sky Sports: "That was good. 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."
He added: "If I wasn't to win this title I'd love to see Chizzy (Chisnall) win it. He's been on the go for years and he is a phenomenal darts player."
