London - Russian 14th seed Daria Kasatkina booked her first Wimbledon quarter-final appearance with a 6-7 (6/8), 6-3, 6-2 victory over Belgium's Alison Van Uytvanck on Monday.
Kasatkina made her Grand Slam last eight debut at the French Open in June and has followed that breakthrough performance with another impressive run at the All England Club.
The 21-year-old rising star was too strong for world number 47 Van Uytvanck, who failed to emulate her shock second round win over last year's Wimbledon champion Garbine Muguruza.
Kasatkina, who failed to get past the third round in her two other visits to the grass-court Grand Slam, will play former Wimbledon finalist Angelique Kerber for a place in the semi-finals.
