Five-time world champion Raymond van Barneveld hammered fellow Dutchman Dirk van Duijvenbode 3-0 in the World Championship at Alexandra Palace in London - but admitted he must do better.
Barney faces Stephen Bunting in the second round of the £1.5m showpiece next Sunday night.
"It's great to get the win but I have to play better - the way I played would not be good enough to beat Stephen Bunting," he said.
In a close opening set Barney took the decider on double eight.
Van Duijvenbode was punished for a remarkable error when he bust his remaining score of 180 in the second set decider, and Barney completed the whitewash with three straight legs in the next.
There was a whitewash too for Bunting against Jyhan Artut.
The former Lakeside champion wasted no time in taking the first set, scoring a 180 and landing double top, double two and tops again to move ahead.
He continued his dominance despite losing the first leg in the next set, landing double eight before breaking Artut's throw.
The St Helens ace then pegged tops to open up a two-set cushion. The German missed chances to take it to a fourth set, Bunting sinking tops to complete a 3-0 victory.
Andy Hamilton suffered his first ever round one exit, the 2012 runner-up losing a dramatic tie-break to 32-year-old debutant Joe Murnan.
"It's amazing to be through," said Murnan, who will take on Robert Thornton or Alan Norris in the second round.
"I was overwhelmed when I drew Andy because he's an excellent player and to win is incredible. He should've won but I took my chance and I'm really pleased but I do feel bad for him."
Mensur Suljovic produced a classy display to see off Holland's Jermaine Wattimena 3-1.
Jamie Caven claimed a straight sets success against New Zealander Rob Szabo. The world number 23 will take on Ricky Evans in the second round.
"I'm coming back after Christmas and that's the main thing," he said.
