Ons Jabeur forged a comeback win over Jelena Ostapenko to get her Stuttgart Open campaign off to a flying start.

Jabeur endured an injury-hit start to 2023 but bounced back with a victory in Charleston and made it six wins on the bounce by overcoming Latvian Ostapenko 1-6 7-6 6-3 on Wednesday.

Next up for Jabeur is a potential quarter-final tie with Elena Rybakina – a rematch of last year's Wimbledon final.

Rybakina, who won the Indian Wells Open in March, came up trumps on that occasion, fighting back to win 3-6 6-2 6–2.

The Kazakh, seeded sixth, overcame German Jule Niemeier 7-5 6-3 in the round of 32 and will now face Beatriz Haddad Maia in the last 16.

World number two Aryna Sabalenka also booked her progression to the last eight, beating 2021 French Open champion Barbora Krejcikova 6-2 6-3.

Coco Gauff, meanwhile, claimed her first victory in Stuttgart as she overcame a tough test from Veronika Kudermetova.

Gauff, the world number five, was taken to a deciding tie-break but ultimately prevailed 6-2 4-6 7-6 (7-3). The American will face Anastasia Potapova in the next round.

Former world number one Karolina Pliskova defeated Maria Sakkari in straight sets in Wednesday's other encounter.
