By Martyn Herman LONDON (Reuters) -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.

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.

A week after reaching her first grass-court semifinal in Eastbourne, Anastasia Pavlyuchenkova continued her late-career resurgence at Wimbledon, shaking off an early deficit to book her 10th Grand Slam quarterfinal and second in a season.
