A number of shock results took the tournament by storm last night including Phil Taylor and Adrian Lewis's singles defeats to Ken MacNeil and John Part of Canada.
The Stoke duo must dust themselves down and win the doubles match at around 4.30pm if they are to stand any chance of progressing.
Scotland, Wales and Australia all hold a commanding 2-0 lead after winning both singles matches and are big favourites to make it through.
Hosts Germany are tied with USA but will be heavily backed in front of their home crowd as they look to set up a potential Quarter-Final showdown with rivals England should Jackpot and The Power rescue the situation.
Northern Ireland open up the day's play against Denmark in another 'winner takes all' encounter, while Belgium and Sweden also level ahead of their all-important pairs showdown.
Reigning champions Holland are all-square at 1-1 going into the decisive doubles game against Austria which will round off the afternoon session.
Two points are awarded for a win in doubles matches. Should the final match score stand at 2-2, a sudden death leg of doubles will decide which team goes through.
Action gets underway at 1.30pm, with selected doubles matches being streamed live from the over the best of nine legs from the Alsterdorfer Stadthalle, Hamburg.
