Former Olympic champion Belinda Bencic sparkled on her return to the elite circuit after her maternity break, leading Switzerland to a 2-1 win over France in the United Cup mixed team tournament on Saturday.
The 27-year-old beat Chloe Paquet 6-3 6-1 in her first WTA Tour-level match since giving birth to daughter Bella in April. She later combined with Dominic Stricker to defeat Elixane Lechemia and Edouard Roger-Vasselin 6-1 7-6(4).
Bencic, who will compete in the 12-26 January Australian Open with a protected ranking, said she was playing at a higher level than she expected.
"The whole comeback went much faster than I anticipated and expected. It's great," said Bencic, who first returned to action in October and played in the Billie Jean King Cup, apart from lower-level tournaments.
"I didn't rush things. I was super careful with starting again. I didn't really want to put time pressure on my comeback. I just wanted to see how it goes every day.
"I think I was ready. There's no point in practising more. It's boring, right? It's better to play competitive matches."
Ugo Humbert had earlier pulled France level at 1-1 with a 6-3 7-5 win over Stricker in the group D contest, battling back from 2-5 down in the second set to prevail and force a mixed doubles rubber at the Ken Rosewall Arena.
