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.

It’s been another incredible run for Kartal, who reached the third round last year before falling bravely to Coco Gauff. Another victory today at SW19 would see the world No51 vault above both Katie Boulter and Emma Raducanu to become the new British women’s No1.
