Lucky loser Bernarda Pera rallied to defeat Spain’s Paula Badosa 3-6, 6-2, 6-3 in an upset-filled opening round on Monday at the Adelaide International in Australia.

Pera dropped the opening set and trailed 3-1 in the third set before racing past Badosa, a wild-card entry playing for the first time since Wimbledon due to a stress fracture in her back.

Qualifiers Anastasia Pavlyuchenkova and Anna Kalinskaya of Russia both ousted top-five seeds. Pavlyuchenkova defeated No. 5 Beatriz Haddad Maia of Brazil 6-3, 6-4, and Kalinskaya outlasted No. 4 Barbora Krejcikova of the Czech Republic 7-5, 3-6, 7-5. Other winners included Ukraine’s Marta Kostyuk, Spain’s Cristina Bucsa and Romania’s Ana Bogdan.
