Iga Świątek is set to play her first match since becoming the world number one in women's singles tennis, representing Poland against Romania in one of seven Billie Jean King Cup qualifiers scheduled across the world for tomorrow and Saturday (April 16).

The 20-year-old has enjoyed a sensational year so far, racking up her 17th successive match win and third consecutive Women’s Tennis Association 1000 event title at the Miami Open earlier this month.

She leads the Polish team alongside Magda Linette, Magdalena Fręch, Maja Chwalinska and Alicja Rosolska for the home qualifier at the Radomskie Centrum Sportu in Radom.

"The last couple of years have shown me that it's not easy to play with your home crowd because it's also some kind of pressure that you can feel, but for sure I'm going to use my experience and the experience that I used in Zielona Góra when we last played [in the Billie Jean King Cup] at home," Świątek said.

"I think this time is going to be easier.

"I can focus more, and take some energy from the crowd, so hopefully I'm going to use that.

"I'm really excited for the match."

Świątek is set to face the world number 123 Mihaela Buzarnescu in tomorrow's second match.

Irina-Camelia Begu, Billie Jean King Cup debutant Andreea Prisacariu and Andreea Mitu complete the Romanian team.
