Katie Boulter gave Great Britain a 2-1 lead in their Billie Jean King Cup play-off against Sweden with a hard-fought win over Kajsa Rinaldo Persson.
The Swede, ranked 372nd in the world, handed Jodie Burrage a surprise defeat on her debut on Saturday.
However, British number one Boulter avoided the same fate on Sunday with a tricky 6-1 7-6 (7-5) victory.
Boulter's performance means Britain can win the play-off if they claim victory in the next singles rubber.
Burrage had been due to play against Caijsa Hennemann in that match but captain Anne Keothavong has swapped the British number two out for Harriet Dart.
