Kenin upsets Ostapenko while Jabeur suffers shock loss at WTA Guadalajara

Former Australian Open champion Kenin, who last reached the quarter-finals of a WTA 1000 event in 2019, booked her place in the last eight with a 6-4, 7-5 win in 1hr 44min.

Kenin's victory came after she knocked out 12th seed Anhelina Kalinina in the second round, and follows a deep run at last week's San Diego Open, where she finished runner-up.

Latvia's Ostapenko, who reached the last eight of the US Open earlier this month, reeled off 36 winners to Kenin's 19, but was left paying the price for a failure to convert break points at key moments.

Ostapenko led 3-0 in the second set, but was unable to force a decider after squandering three break points in the eighth game and six as Kenin served for the match in the 12th game of the second set.

The Moscow-born Kenin will face Canada's 2021 US Open finalist Leylah Fernandez in the last eight - who beat Emma Navarro 6-2, 6-3.

Kenin, 24, has gradually worked her way back to relevance on the WTA Tour after her ranking tumbled to 426 last year following a slew of injuries and upheaval in her coaching set-up.

In other matches on Wednesday, third seed Caroline Garcia of France sailed into the quarter-finals with a 7-5, 6-4 victory over Hailey Baptiste of the United States.

Second seed Maria Sakkari of Greece, meanwhile, romped into the quarter-finals with a 6-2, 6-2 dismissal of Italy's Camila Giorgi.

But while Garcia and Sakkari advanced safely, another seed exited with eighth seed Ekaterina Alexandrova being thrashed 6-1, 6-2 by unseeded American Caroline Dolehide.

In the early hours of the morning, Martina Trevisan beat Ons Jabeur 6-7, 7-5, 6-3, while Victoria Azarenka defeated Veronika Kudermetova 6-2, 6-1.
