Scotland suffer early exit
Scotland, Australia and the Netherlands crashed out of the Betfair World Cup of Darts in the second round, while defending champions England were extended to a deciding leg by South Africa.
Antonio Alcinas and Carlos Rodriguez won the final two legs as Spain shocked Scotland's Gary Anderson and Robert Thornton by a 5-4 scoreline at the Alsterdorfer Sporthalle in Hamburg.
"It's great for us," said Rodriguez. "We'll look forward to tomorrow and anything can happen now. It's very important for us both when we're playing for Spain, we are very proud and every time we get results like this it gets more people in Spain playing darts."
