World champion Luke Littler produced a ruthless display of power scoring and clinical finishing as he swept past Mike De Decker to move into the last 16 of the Poland Darts Open in Krakow.
As one of the top-ranked players handed a first-round bye, world number one Littler wasted little time in seeing off Belgian De Decker 6-1 with a match average of almost 114.
Littler landed three 180s and returned a 100% rate on his doubles, having never looked back after an early break against the Belgian.
Luke Humphries came through a last-leg decider to hold off a fightback from Krzysztof Ratajski, who had been lifted by the home crowd in a first European Tour event to be held in Poland.
World number two Humphries looked in control at 4-1 up, but Ratajski then rallied to break back at 5-3 and again to level the match.
Humphries, though, eventually got over the line when he took out 31 on double four to finally silence the partisan support.
World Championship runner-up Gian van Veen also needed a deciding leg to get past Andrew Gilding 6-5, while Stephen Bunting saw off Niels Zonneveld 6-4 despite having missed 17 darts at doubles.
Jonny Clayton - fresh from his Premier League win in Glasgow on Thursday night - landed six maximums as he beat Adam Gawlas 6-4.
Michael Smith, who was handed a place in the second round after Michael van Gerwen had pulled out due to illness, edged out Joe Cullen in a last-leg decider, while Josh Rock coasted past Limerick's William O'Connor 6-1.
Luke Woodhouse won five successive legs as he came from behind to run out a 6-4 winner over Callan Rydz, who had gone through after Gerwyn Price also withdrew from the trip to Poland.
In Saturday's afternoon session, Cameron Menzies had continued his impressive return to action with a 6-0 demolition of James Wade.
The Scot, whose World Championship had ended in disgrace by punching a table following a first-round defeat which left him with an injured hand, followed up his opening win over Ritchie Edhouse with a fine display, landing 50% on the doubles.
Another Irish competitor Daryl Gurney lost 6-1 to Ross Smith and goes and goes on to play Littler for a place in the quarter-finals, while Wessel Nijman dispatched veteran Gary Anderson 6-2, with a match average of just over 103.
Jermaine Wattimena came through a last-leg decider against fellow Dutchman Danny Noppert, who had missed three match darts, and Chris Dobey coasted to a 6-0 win over Connor Scutt.
World Championship semi-finalist Ryan Searle slipped to a 6-2 defeat by Cristo Reyes, Nathan Aspinall beat Darryl Pilgrim 6-3 and Boris Krcmar saw off Martin Schindler 6-4 which puts him into a last-16 match against Humphries
