Brendan Dolan and Raymond van Barneveld eased into the second round of the PDC World Championship at the Alexandra Palace.
Dolan proved too good for Colin Osborne, who had won his preliminary match against Dennis Lindskjold 4-1, but the Middlesbrough man quickly exited as he suffered a 3-0 defeat to the County Fermanagh man.
Van Barneveld also progressed without any trouble after a comfortable 3-0 win over Jamie Lewis.
The five-time world champion took just 28 minutes to beat the Welshman who won only three legs in the match.
"I feel fortunate to have won in straight sets as Jamie played some good stuff," the Dutchman told www.pdc.tv.
"Jamie did have a quite a few chances to win legs and I was to take the opportunities on offer.
"The 141 to win the match was pretty crucial as Jamie was in control of the leg and had the throw in the fifth leg."
He added: "I still feel I have another World Championship title in me. I wouldn't be here competing if I didn't have that belief."
The first match on stage was a much more dramatic affair with John Henderson claiming a 3-2 win over Dave Chisnall.
Henderson raced into a two-set lead but Chisnall fought back to take the third 3-2 on a 121 finish and then claimed the fourth 3-0.
The world number seven had a dart at the bullseye to claim the match at 3-2 in the final set but missed and Henderson checked out 113 on double top to level things up.
The Scotsman then took the next two legs to seal his place in round two.
In the day's final game, Jamie Caven beat former BDO world champion Jelle Klaasen 3-1 to set up a second round clash with Van Barneveld.
