John Part sent out a warning to his rivals with a ruthless 4-1 win over Richie Burnett in the second round of the PDC World Championship, while Andy Hamilton won a seven-set thriller.
Terry Jenkins also booked his place in the last 16 as action resumed at Alexandra Palace on Tuesday following the Christmas break.
In a fine performance, three-time world champion Part took nine out of the first 10 legs and Burnett's brief rally was soon stopped in its tracks.
Part racked up the first two legs and Burnett's checkout of 136 failed to unsettle the Canadian, who nailed double 16 to secure the set.
There was no let-up from Part as two maximums helped him forge a 2-0 lead in the second and poor finishing from Burnett allowed him to close it out with double four.
'Darth Maple' appeared to be cruising when he swiftly added the third set, but Burnett fought back in the fourth when 13 and 14 dart finishes helped him cut the deficit.
But Part was not about to let Burnett back into the match and his superior finishing paved the way for him to clinch victory with double 16. Part will face in-form Kevin Painter in the last 16.
In the opening match of the day, Jenkins booked his place in the last 16 with a 4-1 victory over Co Stompe.
The Dutchman came into the match hampered by an injury to his right hand, after being bitten by a dog owned by former international footballer Aron Winter back in Holland.
'The Bull' Jenkins produced some superb darts in the early stages of the match - averaging almost 120 in the first two sets, losing just two legs in the process of taking a 3-0 lead.
Stompe nicked the fourth set and had chances to extend the contest but six missed darts at doubles in deciding leg of set five proved costly, allowing Jenkins to close out the match.
"In the early part of the match I produced the kind form I was showing in the practice room," said Jenkins, who now plays Justin Pipe for a place in the quarter-finals.
"I didn't get too worried when Co started to play better, as I had established that three set cushion. Although, I will admit it, was tough to cross that finishing line!"
In the last game of the afternoon session, Hamilton fought back to claim a deciding-set victory over Vincent van der Voort.
Hamilton won the seventh set by three legs to one, taking one dart to hit double 18 where earlier in the contest he had struggled with his finishing.
But he kept his cool to win 4-3 and set up a potential clash with Phil Taylor, who faces Dave Chisnall on Tuesday evening.
