EASTBOPURNE, UK: Barbora Krejcikova faces a race to prove her fitness in time to defend the Wimbledon title after the Czech pulled out of the Eastbourne Open with a thigh injury on Thursday. Krejcikova was due to face France’s Varvara Gracheva in the quarter-finals at Devonshire Park, but announced her withdrawal just hours before the match. The world number 17 suffered the problem on Wednesday during her second-round victory over Britain’s Jodie Burrage.
