PDC Darts Championship: Gerwyn Price and Peter Wright into quarter-finals but Adrian Lewis out
Gerwyn Price accused Simon Whitlock of "pathetic" slow play after beating the Australian 4-2 to reach the PDC World Championship quarter-finals.
Third seed Price edged a scrappy match to set up a last-eight tie against three-time BDO champion Glen Durrant.
The Welshman, a former rugby player, was fined for his own behaviour against Whitlock in a match last year.
"The pace of the game wasn't suiting me, I think Simon did that on purpose," said the 34-year-old .
"It was slowed down to a pathetic pace, but I'll learn from it and do better the next time I come up against that situation."
Price and Whitlock clashed at last year's Grand Slam of Darts where the Welsh player was later found to have brought darts into disrepute after also upsetting Gary Anderson in the final over what the Scot viewed as slow play and over-exuberant celebrations by his opponent.
Price was fined a total of £20,000, which was halved on appeal, and after winning that tournament for a second time in November said he wanted to win over his critics.
Scottish seventh seed Peter Wright edged past the Netherlands' Jeffrey de Zwaan 4-3.
But two-time world champion Adrian Lewis is out after a 4-3 defeat by Belgium's Dimitri van den Bergh.
Durrant, champion at the Lakeside in 2017, 2018 and 2019 before switching to the PDC event, beat fellow Englishman Chris Dobey 4-3 earlier on Saturday.

Peter 'Snakebite' Wright came through a thrilling tie-break to beat De Zwaan 4-3 after losing a 3-0 lead.
Wright appeared to be coasting into the last eight but his Dutch opponent capitalised on three lacklustre sets.
After De Zwaan broke in the first leg of the deciding set, Wright broke back and the match went with throw until Wright secured victory in the eighth leg to set up a quarter-final against Luke Humphries.
"I just ran out of energy, I was feeling really bad up there after the first three sets," admitted Wright.
"The good thing is that games under pressure like this can help lift your level to where it needs to be for the rest of the tournament."
England's Humphries eased past Belgium's Kim Huybrechts 4-1 to reach the quarter-finals for a second successive year.
Lewis twice led by two sets at 2-0 and 3-1 but Van den Burgh came back to win 4-3 and will next face 12th seed Nathan Aspinall.
Lithuania's Darius Labanauskas beat former BDO world champion Steve Beaton 4-2 to set up a quarter-final against reigning PDC world champion Michael van Gerwen on Sunday.
