It was a day of stunning upsets at the Dubai Duty Free Tennis Championships on Wednesday as defending champion Garbine Muguruza, 2021 finalist Barbora Krejcikova, former two-time winner Elina Svitolina and sixth seed Iga Swiatek all failed to advance beyond the second round.
Jil Teichmann was the first to reach the quarter-finals as she defeated Svitolina to win 7-6 6-2.
Jelena Ostapenko defeated Swiatek 4-6 6-1 7-6, qualifier Dayana Yastremska beat second seeded Krejcikova 6-3 7-6 and Veronika Kudermetova overcame fourth seeded Muguruza 3-6 6-4 6-4.
Top seed and world number two Aryna Sabalenka also fell as she was beaten by former champion Petra Kvitova, who won 6-4 6-4.
Ons Jabeur is now the only seed left in the tournament after she overwhelmed Jessica Pegula 6-3 6-1, although two-time former champion Simona Halep is still a strong contender for the title after she defeated qualifier Elena-Gabriela Ruse 6-3 6-2.
