WARSAW, Poland — Ana Bogdan of Romania upset seventh-seeded Nuria Parrizas Diaz of Spain 6-4, 7-6 (3) to advance to the second round of the Poland Open on Tuesday.

Only three singles matches were completed and three were suspended because of rain at the clay-court tournament in the Polish capital.

Tenth-seeded Italian Jasmine Paolini defeated Montenegro’s Danka Kovinic 6-1, 6-1, while France’s Clara Burel advanced by beating Anna Karolina Schmiedlova of Slovakia 7-6 (5), 6-1.

Defending champion Maryna Zanevska of Belgium was down 6-3, 3-1 to lucky loser Kateryna Baindl of Ukraine when their match was suspended.
