The Dutch, without a single player in the top 100, made the semi-finals for the first time since 1997 after Kiki Bertens defeated two-time Grand Slam winner Svetlana Kuznetsova 6-1, 6-4.
Kuznetsova, the world 17, had lost a four-hour marathon against Richel Hogenkamp on Saturday in the longest singles match ever played at a Fed Cup.
The 24-year-old Bertens, ranked at 106, took her Fed Cup singles record to 13 wins and one loss after the Dutch, 2-0 up overnight, claimed a famous win against a Russian team who had Maria Sharapova warming the bench all weekend.
Russia captain Anastasia Myskina said she wasn’t tempted to risk Sharapova, who won both singles rubbers in the country’s 2015 final loss to the Czech Republic.
“No, she had a problem with her left arm and that wasn’t good. We decided on Thursday that she wouldn’t play,” said Myskina.
In Leipzig, 18-year-old Bencic won her third point of the weekend when she teamed up with 35-year-old Hingis to beat Germany’s Andrea Petkovic and Anna-Lena Groenefeld 6-3, 6-2.
Standing 1-1 overnight, Bencic downed Australian Open champion Angelique Kerber 7-6 (7/4), 6-3 before Annika Beck celebrated her maiden singles appearance by seeing off Timea Bacsinszky 7-5, 6-4 to make the tie 2-2.
“I was cheering them on for the first four matches and then I had to go out there,” said Hingis, who returned to the Fed Cup last year for the first time since 1998 in an attempt to play in the Rio Olympics.
Bencic praised Hingis who captured the Australian Open women’s title with Sania Mirza in Melbourne last weekend.
“She did all the great volleys and all the doubles stuff. I was just happy I could play with her,” said Bencic, the world number 11 in singles.
