Wimbledon's automated line-calling technology malfunctioned on Sunday and robbed Anastasia Pavlyuchenkova of a point in her round of 16 clash with Britain's Sonay Kartal.

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.

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.
