The United States grabbed a commanding 3-1 lead in their City Final in Sydney, eliminating Great Britain from the inaugural United Cup.
Frances Tiafoe defeated British No. 2 Dan Evans 3-6 7-5 6-3 to advance the US to the semifinals of the United Cup.
After Katie Swan of the Great Britain team had lost to Madison Keys 2-6 6-3 6-4 earlier, Cameron Norrie defeated Taylor Fritz 6-4 5-7 6-4.
The third-ranked Jessica Pegula defeated Harriet Dart 6-2, 6-0.
Despite losing, Dart and Evans will compete together in the mixed doubles match at the Ken Rosewall Arena with Pegula and Fritz.
The Sydney City Final is one of three City Finals taking place across Australia, which acts as a play-off for the semi-finals.
The winners in Sydney, Perth, and Brisbane will progress, as will the runners-up with the best record – but this will not be Great Britain.
Captained by Tim Henman, GB had been the surprise package at the inaugural mixed team United Cup, having upset Australia and Rafael Nadal’s Spain in the group stage.
However, of the six teams who reached the City Finals, GB possessed the joint worst match win-loss record of the group stage, and the lowest set win percentage.
Elsewhere, Jack Draper is out of Adelaide International after being beaten in straight sets by Karen Khachanov.
The eighth seed won 6-4 6-2 and will play third seed and fellow Russian Daniil Medvedev in the quarter-finals.
