Great Britain trail the USA in their United Cup tie despite Cameron Norrie’s win over Taylor Fritz in Sydney.
After the ‘city final’ had begun with Katie Swan being defeated by Madison Keys, Norrie got the better of Fritz across three sets over two hours and 15 minutes at Ken Rosewall Arena.
The British number one made the decisive break in the ninth game of the third set as he triumphed 6-4 5-7 6-4.
GB had earlier gone 1-0 down as Keys came from behind to beat Swan 2-6 6-3 6-4.
Harriet Dart was later beaten 6-2 6-0 by world number three Jessica Pegula before Dan Evans takes on Frances Tiafoe.
If that leaves the score at 2-2, it will go down to a mixed doubles contest, with Dart and Evans set to play Pegula and Tiafoe.
The winner advances to the semi-finals that start on Friday, as will the best runner-up from the three city finals.
