Paula Badosa continued her fine season with a victory at the Serbia Open, having also reached her maiden WTA singles final on Saturday.
Badosa had to play two matches on Saturday, first progressing to the final by beating lucky loser Viktoriya Tomova 6-1 6-2.
The Spaniard's straight-sets win took only 63 minutes, so she still had plenty in reserve heading into the showdown with qualifier Ana Konjuh, but Badosa did ultimately not need the energy.
She was 6-2 2-0 up when Konjuh – who defeated Maria Camila Osorio Serrano earlier on Saturday – retired due to a right hip injury, sealing Badosa's triumph.
Badosa, 23, rounded off a successful week without having dropped a set. She had previously reached two semi-finals in her last two tournaments – in Charleston and Madrid, both against Ash Barty.
