headline: Rage against the machines: ignore the fury at Wimbledon, AI in sport works | Sean Ingle
dek: We are all suckers for a good story. And there was certainly a cracking two‑parter at Wimbledon this year. First came the news that 300 line judges had been replaced by artificial intelligence robots. Then, a few days later, it turned out there were some embarrassing gremlins in the machine. Not since Roger Federer hung up his Wilson racket has there been a sweeter spot hit during the Wimbledon fortnight. First the new electronic line-judging system failed to spot that Sonay Kartal had whacked a ball long during he

quick_read: At Wimbledon in July 2025, organizers replaced 300 human line judges with an artificial intelligence electronic line-judging system. Shortly after deployment, the new system failed to detect that player Sonay Kartal had hit a ball long during a match.

The case illustrates both automation of sports officiating and the operational risk of errors in high-profile competition. The truncated excerpt does not provide error rates, correction procedures, or longer-term performance data needed to judge reliability.
limitation: Article text is truncated mid-sentence and does not provide full match context, error rate, or whether the missed call was corrected.
tag: Model-validated trace
key_points: Wimbledon implemented a new electronic line-judging system in 2025 described as artificial intelligence robots. | The deployment replaced approximately 300 human line judges. | During a match involving Sonay Kartal, the system failed to detect a ball hit long. | The incident was reported as embarrassing gremlins in the machine days after the replacement was announced.
rundown: By 15 July 2025, Wimbledon had replaced 300 line judges with an AI electronic line-judging system. Days after the rollout, the system failed during a match to spot that Sonay Kartal had hit a ball long, an incident described as gremlins in the machine.

Automated line-calling matters because it changes officiating jobs and match outcomes at a major tournament. It remains unclear from the excerpt how frequent such errors were, how they were resolved, or whether overall accuracy improved compared to human judges.
