Five-time Grand Slam champion Iga Swiatek clinched back-to-back wins to lead Poland into their first Billie Jean King Cup semi-final on Saturday. Swiatek, the world number two in singles but playing her first doubles match in the tournament since 2019, teamed with Katarzyna Kawa to defeat Marie Bouzkova and Katerina Siniakova 6-2, 6-4 to complete a comeback 2-1 victory over the Czech Republic. In Monday’s semi-finals, Poland will face 2023 runners-up Italy who earlier edged out Japan 2-1. The Czechs had claimed the first point of the quarter-final when Bouzkova defeated Magdalena Frech 6-1, 4-6, 6-4. Swiatek, however, levelled the tie with a 7-6 (7/4), 4-6, 7-5 triumph over Linda Noskova before returning to the court to help sweep the deciding doubles. Like Swiatek, Jasmine Paolini was a also a two-time winner Saturday as she starred for Italy in their win over Japan. Ena Shibahara won the opening singles after recovering to beat Elisabetta Cocciaretto 3-6, 6-4, 6-4, but French Open and Wimbledon runner-up Paolini levelled the tie with a 6-3, 6-4 win over Moyuka Uchijima. World number four Paolini then teamed up with Sara Errani to defeat Japanese pair Shuko Aoyama and Eri Hozumi 6-3, 6-4 in the decisive doubles rubber. “(It) wasn’t easy for me because you enter (trailing) 0-1. But I’m happy with singles and of course with doubles,” said Paolini, who has enjoyed a breakthrough season and participated at the WTA Finals last week.
