Adrian Lewis and Dave Chisnall avoided any upsets as the holders England comfortably beat South Africa at the World Cup of Darts.
Lewis coasted past Devon Petersen recording a 4-0 win in the first game to set them on their way.
South Africa had an early chance to break the throw in the first leg but Petersen failed to take it and Lewis took full advantage before then breaking his opponent to make it 2-0. The Englishman was untroubled from then on, reeling off a further two legs to make it 4-0.
Chisnall never needed to get out of second gear as he raced into a 2-0 lead over Deon Oliver in the second tie.
The South African looked like taking a scrappy third leg but missed four darts at a double before Chisnall hit double five for a 3-0 lead.
The St Helens man ensured England didn't drop a leg on the night by winning the final leg to set up a quarter-final with Austria.
"It's a great thrill to play for your country and I have got a great partner which makes it easy for me," said Chisnall.
"I'm enjoying it and we are relaxed and can go far in the tournament. It's Austria next and they are a tough team who played well tonight but we are both good enough to beat them."
Lewis added: "We didn’t want it to go to doubles tonight, so I had to get the job done to start and then Dave had to finish it off.
"It’s a massive bonus for us that we get on so well, we’re up there and have a good laugh and just relax. We’re here as a team and I really do think we’ve got a great chance of winning this."
