For the first time in its 148-year history, Wimbledon has removed all line judges from its courts. This marks a significant shift for a tournament known for its deep-rooted traditions, from the all-white dress code to strawberries and cream. But in 2025, the All England Club embraced a new chapter by fully adopting electronic line calling across all 18 match courts.

Why line judges were removed

The decision to eliminate line judges was driven by a desire for greater accuracy and consistency in officiating. In previous years, Wimbledon employed around 300 line judges to monitor the boundaries of play. However, with the rise of advanced technology and its successful implementation at other Grand Slam tournaments like the Australian Open and US Open, Wimbledon followed suit.

Tournament officials emphasized that the move was not taken lightly. After extensive testing and consultation, they concluded that the technology was reliable enough to replace human judgment. The goal was to ensure that players compete under the same conditions they experience at other top-level events throughout the year.

What electronic line calling is and how it works

Electronic line calling uses a system known as Hawk-Eye Live. This technology relies on a network of high-speed cameras—up to 12 per court—that track the ball’s trajectory in real time. When a ball lands near a line, the system instantly determines whether it was in or out. An automated voice then announces the call, and a light flashes in the umpire’s chair to confirm the decision.

Unlike the previous challenge system, where players could contest a call and request a video review, the new system is final. There are no challenges, no replays to sway the outcome. The call is made within milliseconds, and the match continues without interruption.

What happens to the former line judges

While the majority of line judges are no longer needed, around 80 have been retained as match assistants. These individuals support the chair umpire, help manage player logistics, and are trained to step in if the electronic system fails. Their presence ensures that a human element remains, even in a tech-driven environment.

Who makes the calls now

The voices used for the automated calls were pre-recorded by Wimbledon staff and local guides. To avoid confusion on adjacent courts, the system alternates between male and female voices. This attention to detail reflects Wimbledon’s effort to maintain clarity and atmosphere, even as it modernizes.

Balancing tradition and innovation

Wimbledon’s leadership has acknowledged the tension between preserving tradition and embracing innovation. While some fans and officials feel nostalgic about the loss of the iconic line judge, the shift reflects the broader evolution of the sport. With the French Open now the only Grand Slam still using human line judges, Wimbledon’s move aligns it with the global tennis landscape.

In the end, the grass is still green, the players still wear white, and the pursuit of excellence continues—just with a little more help from technology.
