USA qualified for the Final Four of the United Cup by beating Great Britain 3-1 in the tie that takes place in sydney.
The crossing began tied, after the victories of the North American Madison Keys on Kate Swan by 2-6, 6-3, 6-4 and the British Cameron Norrie on Taylor Fritz by 6-4, 5-7 and 6-4.
But the next two points went to the US team: Jessica Pegual defeated Harriet Dart by 6-2 and 6-0 and Frances Tiafoe a Daniel Evans by 3-6, 7-5 and 6-3, after a laborious comeback.
The quinto point, the mixed doubles, will be played anyway, because the best among the three losing teams will also go to the final phase.
In Perth the tie is played Greece-Croatia and in Brisbane the one that faces Italy and Poland. Both also started 1-1, but the Italians then provisionally gained the advantage.
