Swiatek will play her first match as world number one when she leads Poland against Romania in the Billie Jean King Cup this weekend, desperate to improve her record on home ground. Swiatek, the first ever Pole to ascend to the top of the rankings, lost both singles matches she played the last time she appeared in front of her own crowd in a 2019 play-off against Ukraine. "The last couple of years have shown that it's not easy to play with your home crowd because it's the same kind of pressure you feel," said the 20-year-old on Thursday who was still outside the top 60 three years ago.
