Poland’s world No. 1 Iga Swiatek handed Romania’s Andreea Prisacariu a double bagel en route to victory in their Billie Jean King Cup qualifier on Saturday, securing the decisive third point in the tie and a spot in November’s finals for the first time.

Swiatek, who put her country up 2-0 on Friday by thrashing Mihaela Buzarnescu 6-1, 6-0 for an 18th straight win, continued to stamp her authority on the tie as the 20-year-old broke Prisacariu six times in Radom, Poland.

Marketa Vondrousova and Karolina Muchova won the doubles decider for 11-time champions Czech Republic to clinch their finals berth with a 3-2 victory over Britain after beating Harriet Dart and Katie Swan 6-1, 7-5 in Prague.

Vondrousova earlier picked apart Emma Raducanu 6-1, 6-1 as the teenager struggled with blisters on her right foot before Dart levelled the tie at 2-2 with a 6-0, 5-7, 6-2 win over 16-year-old Linda Fruhvirtova.

Also advancing to the finals are Kazakhstan, who progressed at the expense of Germany with Elena Rybakina coming from a set down to get past Angelique Kerber 4-6, 6-3, 7-5 in Nur-Sultan.

Italy also advanced after Camila Giorgi, who had given her country a 2-0 lead on Friday, secured the decisive point in their victory over France in Sardinia with a 6-2 6-0 thrashing of Harmony Tan.
