World number 31 Alex Eala produced one of the biggest upsets of the WTA season on Thursday, battling back from 4-1 down in the opening set to stun world number two Elena Rybakina 7-5, 6-4 and reach the quarter-finals of the Berlin Open.
The 21-year-old Filipina looked in danger of being overpowered early by one of Wimbledon's leading contenders as Rybakina raced into a commanding lead. Instead, Eala delivered a fearless response, winning six of the next seven games to seize control of the match before completing a statement victory over one of the most formidable players in women's tennis.
