Big upset as Jabeur knocks out Cibulkova
Seventh seed Domonika Cibulkova was knocked out of Roland Garros on Wednesday, going down in straight sets to World No 114 Ons Jabeur.
The 22-year-old Tunisian had never gotten past the first round of a Grand Slam prior to this week's event in Paris, but now finds herself in the third round after a stunning 6-4, 6-3 upset victory over the seventh seed.
Jabeur - whose career highlight came in 2011 when she French Open junior event - also becomes the first Arab woman to reach the third round of a Grand Slam.
After only narrowly defeating Miyu Kato in the final round of qualifying, Jabeur has made the most of her opportunity, defeating Ana Bodgan in the first round before following that up with an unlikely win over Cibulkova.
The first set came down to a solitary break point in the ninth game, which Jabeur converted for a 5-4 lead before holding on to serve out the set.
Cibulkova needed a response and she looked to have found it with an early break for a 3-1 lead, but Jabaur went on a tear, winning the final five games to leave Cibulkova shell shocked.
Jabeur finished with a whopping 30 winners and only 17 unforced errors, breaking serve four times to set up a third-round clash with 2015 semifinalist Timea Bacsinszky.
Bacsinszky very much looked the part as she dispatched Madison Brengle 6-0, 6-2 on Wednesday.
Other second-round results on the day saw 11th seed Caroline Wozniacki and 13th seed Kristina Mladenovic book their places in the third round.
Wozniacki blanked Françoise Abanda 6-0, 6-0, while Mladenovic saw off Sara Errani 6-2, 6-3.
Eighth seed Svetlana Kuznetsova also advanced late in the evening, beating Océane Dodin 7-6 (7-5), 5-7, 6-3 in a testing encounter.
Earlier, there were wins for defending champion Garbine Muguruza and Venus Williams, while Petra Kvitova was knocked out.
