Wimbledon bosses have defended the use of AI line judges after Jack Draper said the technology was not "100% accurate". The British No 1 said it was "a shame" human line judges were ousted after crashing out in the second round to the 36-year-old former finalist Marin Cilic. Draper, 23, grew frustrated with the AI-enhanced Hawk-Eye technology during Thursday's match, holding his arms out in disbelief after one of his opponent's serves was not called out in the fourth set. "I don't think it's 100% accurate in all honesty," he said in his post-match press conference. "A couple of the ones today, it showed a mark on the court. There's no way the chalk would have showed that. I guess it cannot be 100% accurate – it's millimetres."
