Wimbledon issue statement after reviewing major controversy and announce big change

Wimbledon have made changes to the controversial AI-assisted line-calling system after admitting a major error had occurred over the weekend. There were farcical scenes in Anastasia Pavlyuchenkova's match against Sonay Kartal after the Hawk-Eye system had been accidentally disabled.

A shot from Kartal - which was clearly out - was not called by the automated system, meaning Pavlyuchenkova did not win the game. The umpire opted to replay the point, leaving Pavlyuchenkova incensed.

"They stole a game from me. They stole it," she fumed on Centre Court in scenes that didn't help Wimbledon's image after they controversially decided to scrap the 147-year tradition of using human line judges.

The All England Lawn Tennis Club has now explained what happened - and taken steps to ensure it doesn't happen again.

"Following our review, we have now removed the ability for Hawk-Eye operators to manually deactivate the ball tracking," the tournament's organisers said in a statement to BBC Sport.

"While the source of the issue was human error, this error cannot now be repeated due to the system changes we have made."

Wimbledon chief executive Sally Boulton earlier explained that umpire Nico Helwerth was having a day off on Monday, as part of normal procedure, following the controversy.

"We have rotation of our umpires regularly. A little bit like the players, the umpires also need rest days throughout the tournament," Bolton told BBC Sport.

"He's having a rest day today. He's fine. It's really important to say that the umpire followed the protocols in place. He did what he needed to do on court and acted entirely correctly."

Pavlyuchenkova should have won the point, which came when Kartal was game point down at 4-4. But instead Helwerth decided to replay the point, which Kartal went on to win.

The Russian went on to win the match 7-6, 6-4 and explained the situation in her post-match press conference. "It was very confusing in the beginning because the ball looked very long to me. I tried to play it, but it was quite long, so it was even tough to sort of played it," she said.

"Then I kind of stopped. The chair umpire stopped, as well, the point. Then I was pretty sure that it was my game because I saw it was very long. Then I thought I would just sit on the chair, but then he started calling.

"We were waiting for decision as the system was down, but I was expecting to hear if they say the ball was in or out. Instead they just say, Replay the point. It was tricky especially in that moment. It was very crucial moment in the match.

"I expected different decision. I just thought also chair umpire could take initiative. That's why he's there for sitting on the chair. He also saw it out, he told me after the match. I thought he would do that, but he didn't.

"Also, I expected, so maybe they call in or out. Instead they just said replay. I don't know if it's something to do because she's local, but yeah, that was particular moment."
