Harriet Dart secured victory for Great Britain in their opening United Cup tie against Australia on Friday with a straight-sets victory over Maddison Inglis.
Britain were 2-0 up in the best-of-five contest heading into day two, thanks to wins for Cameron Norrie and Katie Swan on day one.
GB needed just one win in the three matches scheduled for Friday and Dart ensured there would be no comeback from the host nation with a comprehensive 6-4, 6-4 win over Inglis, a late replacement for the injured Ajla Tomljanovic.
“Maddy played really great tennis today and I had to work for it,” Dart said on unitedcup.com. “First match of the year, I was really nervous, but the crowd were great.”
Dan Evans lost to Jason Kubler 6-3, 7-6 (3) and there was also defeat for Dart and Evans in the doubles but victory was already assured.
Britain’s second group game against Spain begins on Saturday, with Norrie handed the daunting task of taking on Rafael Nadal.
Greece lived up to their tag of favourites with a 4-1 win over Bulgaria in Perth, while Italy were 3-2 winners against Brazil. The USA were also 4-1 winners over the Czech Republic.
The winners of the six groups being held in Brisbane, Perth and Sydney go through to city finals to decide the makeup of the semi-finalists.
