Italy's Martina Trevisan pulled off a stunning comeback to defeat top-seeded Ons Jabeur of Tunisia 6-7 (4), 7-5, 6-3 on Wednesday in the third round of the Guadalajara (Mexico) Open Akron.

With Jabeur up a set and serving for the match at 5-4 in the second, she went ahead 30-0 before Trevisan began her rally. Trevisan won the next four points to break serve, then won the next two games to force a third set.

Trevisan recorded two of the three service breaks in the final set to advance to her second quarterfinal in a WTA 1000 event this year. She also reached the quarters at Miami in March.

In earlier matches on Wednesday, Americans Sofia Kenin and Caroline Dolehide pulled off upsets.

Kenin ousted Latvian sixth seed Jelena Ostapenko 6-4, 7-5 by saving four of five break points while Ostapenko committed seven double faults. Dolehide completed a 6-1, 6-2 sweep of No. 8 seed Ekaterina Alexandrova of Russia with the help of three aces.

Three other Americans were in action on Wednesday, but all three fell. French third seed Carolina Garcia downed Hailey Baptiste 7-5, 6-4, Canadian Leylah Fernandez breezed by Emma Navarro 6-2, 6-3, and Emiliana Arango of Colombia defeated Taylor Townsend 7-5, 1-6, 6-4.

In other action, second-seeded Greek Maria Sakkari bested Italy's Camila Giorgi 6-2, 6-2, and 10th-seeded Belarusian Victoria Azarenka crushed seventh-seeded Veronika Kudermetova of Russia 6-2, 6-1.
