Wimbledon champion Garbine Muguruza beat Caroline Garcia, her second match in 24 hours, to reach the semi-finals of the Dubai Duty Free Championships.
Muguruza, who finished her quarter-final the night before at 02:00 local time, beat the Frenchwoman 7-5 6-2.
The Spanish second seed, 24, will play Russia's Daria Kasatkina next.
Germany's former world number one Angelique Kerber will play reigning champion and top seed Elina Svitolina in Friday's other semi-final.
Two-time Grand Slam champion Muguruza is hoping to reach her second straight final, having lost to Petra Kvitova in the Doha final last week.
