Poland have reached the Billie Jean King Cup finals for the first time after top-ranked Iga Swiatek overpowered Andreea Prisacariu of Romania.

Swiatek needed just 52 minutes to dispatch Prisacariu 6-0 6-0 to extend her singles winning streak to 19 in her second competitive match since becoming world No.1 for the first time.

“It took us a few years, step by step, to progress and qualify finally,” the 20-year-old Swiatek said in an on-court interview.

“Hopefully in the finals we’re going to show even more progress. I’m really proud of us.”

Swiatek’s victory made it 3-0 for Poland in the best-of-five qualifier for the finals in November.
