Irina-Camelia Begu and Timea Babos will meet in the Brasil Tennis Cup final after winning their semi-finals in straight sets on Thursday.
Second seed Begu took advantage of Monica Puig's service struggles to win 6-3 6-3 in Florianopolis and set up a showdown with Babos on Friday.
Puig, seeded three, racked up seven double faults and won only 55 per cent of points on her first serve to miss out on a place in the final.
Sixth seed Babos ensured there will be no all-Romania final by ousting outsider Ana Bogdan 7-6 (10-8) 6-3.
Both finalists will be eyeing their first WTA titles this year on Friday.
