The Netherlands became the first country to reach the knockout rounds of the Davis Cup Finals undefeated, beating the United States in Glasgow, while Serbia pulled out a clutch win over Canada.

Canada advance despite the loss and the same can be said for the US.

Back-to-back singles wins set up a Dutch win at Glasgow's Emirates Arena.

Tallon Griekspoor beat Tommy Paul 7-5, 7-6, before Botic van de Zandschulp defeated Taylor Fritz 6-4, 7-6.

Rajeev Ram and Jack Sock won the doubles to add some respectability to the score for the US, who will finish second in Group D.

In Group B, being played at Valenica's Pavelló Municipal Font de Sant Lluís, Canadian Vasek Pospisil was forced to retire hurt in the deciding doubles match.

That gave Serbia a 2-1 win and keeps their hopes of qualification alive, while Canada are through.

Laslo Đere defeated Gabriel Diallo 6-2, 6-2 to give Serbia the advantage, but Felix Auger-Aliassime saw off Miomir Kecmanović 6-3, 6-4.

Canada top the group as things stand, but are set to finish second.

If South Korea beat Spain, Serbia will go top; the host nation will win the group should they defeat South Korea.
