Wimbledon has updated its electronic line-calling system after a human error caused the Hawk-Eye to fail during a fourth-round match. The All England Club has now issued a statement saying that they have made a crucial change that will ensure that the mistake doesn’t happen again.

Unseeded Anastasia Pavlyuchenkova recovered from being robbed of a crucial point by an automated line-calling malfunction to beat Britain's Sonay Kartal 7-6(3) 6-4 to reach the Wimbledon quarter-finals on Sunday for the second time.

Sonay Kartal was knocked out of Wimbledon after her Russian rival claimed the British player got special treatment when the electronic line calling failed on Centre Court. Anastasia Pavlyuchenkova, 34, recovered to knock the last British female out of the singles 7-6 6-4.
