Andy Murray earned the win that ensured Britain would return to the World Group in 2014 for the first time since 2008, when he defeated Croatia's Ivan Dodig last weekend.
That saw Britain take an unassailable 3-1 lead in the World Group play-off clash with Croatia, a day after Murray and Colin Fleming had put Britain back in front in the doubles.
They defeated Mate Pavic and Dodig in their doubles tie for a 2-1 lead following Murray's win over 16-year-old Berna Coric and Dan Evans' defeat to Dodig on day one. Evans beat Pavic in the dead rubber to secure a 4-1 victory.
Murray was playing his first Davis Cup tie for two years against the Croatians in Umag but hinted that he will be a regular for Britain in the World Group.
American reached the quarter-finals of this year's Davis Cup before losing to Serbia in Washington DC.
For that match-up they played Sam Querrey and John Isner in the singles with the Bryan brothers playing in the doubles. Captain Jim Courier selected a hard indoor court for that fixture.
The winner of the tie between USA and Britain will face either Italy or Argentina in the quarter-final.
Amongst the other first round highlights, Novak Djokovic could come against Roger Federer and/or Stanislas Wawrinka as Serbia take on Switzerland in Belgrade; while the current champions, the Czech Republic, who will face Serbia in this year's final, will open against the Netherlands at home.
The first round is due to be played between 31 January-2 February next year.
