For the first time in its 148-year history, Wimbledon 2025 has replaced human line judges with artificial intelligence (AI) technology. The All England Lawn Tennis Club (AELTC) announced this change in October 2024, introducing Live Electronic Line Calling (ELC) powered by Hawk-Eye. As top players like Carlos Alcaraz and Barbora Krejčíková defend their titles, this shift to AI is transforming tennis, bringing more accuracy but sparking debate. Here’s a look at how it works, what it means, and why it’s causing a stir.
No More Line Judges
Wimbledon’s line judges, known for their cream berets and navy blazers, have been a beloved part of the tournament. Their calls of “out” or “fault” were iconic. But in 2025, all 18 courts use AI to make these calls. The Hawk-Eye system, first used in 2007 for player challenges, now makes instant decisions without human help. Sally Bolton, AELTC’s chief executive, said this change ensures “maximum accuracy” after successful tests in 2024.
Other major tournaments, like the US Open (since 2020) and Australian Open (since 2021), already use ELC. The ATP Tour plans to do the same in 2025, showing that tennis is moving toward technology.
How AI Line Calls Work
The ELC system uses 12 cameras and microphones to track the ball’s path in real-time. It creates a 3D image to see exactly where the ball lands and uses an AI voice to call “out” or “fault.” Unlike before, players can’t challenge these calls, which cuts down on arguments and speeds up matches. Wimbledon also uses AI for fan features, like the ‘Likelihood to Win’ tool and a ‘Match Chat’ assistant to answer questions during games.
Mixed Feelings About AI
People have different views on this change. Some love the accuracy, saying it prevents mistakes like those that led to John McEnroe’s famous 1981 outburst, “You cannot be serious!” Fans at other tournaments enjoy seeing close calls on screens instantly. But others miss the human line judges, who added excitement and personality. Some students protested outside Wimbledon, holding signs like “AI took my job,” worried about the 300+ line judges losing work. While 80 judges stay to help chair umpires, the change feels big.
Players are split too. Some, like Rafael Nadal, like the precision, but others think tennis loses its human spark. On X, fans like @TennisFan123 praise the “perfect calls,” while @WimbledonNostalgia calls the AI matches “too cold.”
What This Means for Tennis
Wimbledon’s AI use could push other sports, like soccer or cricket, to rely more on technology for calls. But some decisions, like handling crowd noise, still need humans, so a mix of AI and people might be the future. The change saves money on training judges but risks upsetting fans who love Wimbledon’s traditions. Keeping human chair umpires and ball kids shows the tournament wants to hold onto some of its classic feel.
A New Wimbledon
As Wimbledon 2025 continues with stars like Jack Draper and Emma Raducanu, the absence of line judges marks a new chapter. AI makes matches faster and fairer, but it changes the heart of the tournament. By using this technology, Wimbledon is leading the way for sports worldwide. Whether it adds to or takes away from the magic of SW19, one thing is clear: tennis is changing, and AI is now part of the game.
