'They stole the game' - electronic line call fails at Wimbledon

Play was stopped during Sonay Kartal's last-16 match at Wimbledon when the electronic line-calling system failed to call a ball out.

There was no 'out' call to a Kartal backhand that had gone long at 4-4 in the first set, with chair umpire Nico Helwerth instead shouting "stop, stop".

The Briton's opponent, Anastasia Pavlyuchenkova, had already stopped as she saw the ball was out - and a TV replay showed it was by some distance.

Addressing the crowd, Helwerth said: "We're just going to check if the system was up and running, because there was no audio call."

After a telephone call, he said the electronic system "was unfortunately unable to track the last point so we will replay the point".

Had the ball been correctly called out, Pavlyuchenkova, who had the advantage, would have won the point and taken the lead.

Instead, it was replayed, Kartal won the point and went on to break for a 5-4 lead.

A frustrated Pavlyuchenkova was heard telling the umpire at the changeover: "They stole the game from me. They stole it."

A spokesperson for the All England Club said: "Due to operator error the system was deactivated on the point in question.

"The chair umpire followed the established process."

The automated line-calling system, which was introduced at Wimbledon for the first time this year, has been under scrutiny this week, with several players questioning its accuracy and sound level.

Debbie Jevans, chair of the All England Club, said on Friday she was confident in the accuracy of the electronic line calling and in the decision to bring it in.
