Tuesday proved to be a day of shocks at the Dubai Duty Free Tennis Championships.
First, two-time champion Elina Svitolina was humbled in the first round by American qualifier Jennifer Brady before Belinda Bencic, winner here 12 months ago, crashed out to Russia's Anasatsia Pavlyuchenkova.
They were not the only seeds to tumble, however, as Sofia Kenin, winner of the Australian Open just a few weeks ago, fell to the in-form Elena Rybakina.
Today's action sees Australian Open quarter-finalist Ons Jabeur take on world No 2 Simona Halep on Centre Court.
In reaching the last eight at Melbourne Park, Jabeur became the first Arab woman to reach the last eight of a Grand Slam.
Can the Tunisian world No 45 pull off an upset over the Romanian?
We'll bring you updates of each match throughout the day.
