Wimbledon Embraces AI: A Historic Shift from Tradition in Line Calls

In a groundbreaking move for the world of tennis, Wimbledon has announced that it will replace human line judges with artificial intelligence (AI) technology to make the all-important "out" and "fault" calls, starting in 2025. The decision by the All England Club signals a remarkable step forward, with the oldest Grand Slam tournament embracing cutting-edge technology to enhance accuracy and consistency. The switch from traditional line judges to electronic line-calling was carefully considered after thorough testing at the 2024 tournament, marking the end of an era for Wimbledon.

Sally Bolton, chief executive of the All England Club, emphasized that AI-based line-calling technology has now reached a level of robustness and reliability suitable for Wimbledon’s high standards. She acknowledged that while this change reflects progress, it also honours tradition, saying, “Line umpires have played a central role in our officiating set-up at the championships for many decades, and we recognize their valuable contribution and thank them for their commitment and service.” For players, the AI system will provide the same standardized conditions they are already accustomed to at other tournaments, such as the Australian Open and U.S. Open, where electronic line-calling has replaced human judges.

This move is about more than just technology—it’s about finding the right balance between Wimbledon’s storied heritage and the demands of the modern game. For decades, line judges have been part of the visual identity of Wimbledon, donned in distinctive, elegant uniforms that contribute to the tournament's timeless appeal. However, the All England Club has been adapting, recognizing the need for innovation to meet the highest levels of precision in officiating. Bolton highlighted that Wimbledon has a “responsibility to balance tradition and innovation,” a theme that resonates strongly with this decision to integrate AI into the heart of the tournament’s operations.

In addition to adopting AI for line calls, Wimbledon organizers have adjusted the schedule for the marquee matches. From 2025, the ladies' and gentlemen's singles finals will be held at a later time—4 p.m. local time—on the final weekend following the doubles finals. This scheduling change aims to maximize global viewership. Bolton notes that it allows the tournament’s climactic moments to “build towards the crescendo” as champions are crowned in front of the largest worldwide audience.

As Wimbledon steps into the future with these bold changes, it joins other Grand Slam tournaments relying on AI-driven technology for officiating, leaving the French Open as the only major still using human line judges. While this shift may evoke nostalgia for traditional fans, it positions Wimbledon at the forefront of tennis innovation, promising enhanced accuracy and fairness.
