Bernarda Pera secured her first WTA Tour title after defeating Aleksandra Krunic 6-3 6-3 at the Budapest Grand Prix.

Pera, who won two qualifying rounds to reach the main draw in the tournament, will likely re-enter the top 100 in the world rankings after her triumph.

The pair advanced to Sunday's showpiece in Hungary without dropping a set, teeing up a mouth-watering clash between the world number 105 Krunic and 130th-ranked Pera.

Pera, the lowest-ranked contender to play for the title in Budapest since world number 112 Yvonne Meusburger lost to Simona Halep in 2013, raced out the blocks to claim an early 3-0 lead, with the Serbian winning just one point.

Krunic then squandered four break-point opportunities in the fifth game before the American required five attempts to claim the first-set lead, with both missing a plethora of chances.

Moscow-born Krunic seemed to regain her composure, with the pair exchanging breaks to leave the match finely poised at 3-3 in the second set.

But Pera, appearing in her first tour-level final, broke again once more in the following set before holding out on her serve to seize the initiative.

The 27-year-old required just one opportunity to wrap up the match and her maiden title, while she achieved her third career win over Krunic in as many meetings.

Reigning champion Yulia Putintseva's Budapest Grand Prix title defence came to a disappointing end after she was beaten in the semi-final in straight sets by Aleksandra Krunic.

The Kazakh Putintseva struggled to get going, failing to convert any of her seven break points, as the Serbian Krunic broke her serve four times en route to a 6-2 6-2 win.

Bernarda Pera will await Krunic in the final in Hungary, after her 6-3 6-4 victory over Anna Bondar.

Bondar raced out to an early 3-0 lead in the first set, but Pera rattled off six games in a row to take the opener.

The Croatian-born American then won the first three games of the second set, before overcoming a desperate late Bondar charge to break her at 5-4 and finish things off.

Sunday's final will be the third meeting between Krunic and Pera with the latter winning both of the previous contests, firstly in the quarter-finals of the Guangzhou Open in 2018 and then in Moscow in 2021.

At the Ladies Open Lausanne, qualifier Olga Danilovic cruised through to the final with a 6-3 6-2 victory over Russian Anastasia Potapova.

Danilovic won her first WTA Tour singles event in Moscow in 2018, overcoming Potapova after three sets.

And the world number 124 was victorious against Potapova once more in Switzerland to seal her place in her second WTA Tour singles final.

The Serbian 21-year-old will meet Petra Martic in the decider on Sunday after Martic overcame sixth seed Caroline Garcia 6-4 1-6 6-3.

Neither player had dropped a set on their way to the semi-finals, but things at Lausanne were tied up at one set each after two.

Garcia had won all three of her previous meetings with Martic, but the Croatian's two crucial breaks of serve in the final set were telling, as she held her nerve to reach the final against Danilovic.

Elena-Gabriela Ruse was the only seeded player to fall in the opening round of the Hungarian Grand Prix on Monday, going down in three sets to Kamilla Rakhimova.

The seventh seed made numerous errors and was undone against Russia's world number 107 Rakhimova, who hit 23 winners en route to a 6-4 5-7 6-3 victory in Budapest.

Rakhimova will now face Ukraine's Lesia Tsurenko, who beat Carolina Alves 6-4 6-1 to reach the last 16.

At the Ladies Open Lausanne, meanwhile, another seventh seed in Tamara Zidansek was eliminated at the first hurdle by Anna Kalinskaya with a 7-6 (7-2) 3-6 6-3 defeat.

Sara Sorribes Tormo, the only other seeded player in action on day one in Switzerland, had far less trouble in seeing off Lauren Davis 6-2 7-6 (7-1).
