Wimbledon Introduces Video Challenge Technology This Season.

Video review systems will make its debut at Wimbledon this year.

Competitors are granted the right to challenge specific calls from the official, following the protocol already in operation at each of the American Grand Slam and the Australian Open.

This innovation will be operational on the main stadium and the number one court for the duration of the tournament and on the other four featured courts when they are staging singles matches.

This move comes just a year after the All England Club implemented electronic line calling, which brought an end to the centuries-old tradition of line officials.

What Can Be Reviewed?

Competitors cannot to challenge the call of the ELC system, but are allowed to request the official to re-examine other decisions, including:

• Whether a tennis ball has double-bounced.
• If a ball touched an opponent's racquet or body on the way past.
• Possible hindrance at the conclusion of a point.

Notably, there is no limit on the number of challenges a competitor can initiate.

Practical Application

A recent case took place in a recent tournament recently, where Daniil Medvedev used the review system against his opponent.

The British player admitted it was a difficult call for the official, but thought his opponent had "used the regulations quite well."

Official Aurelie Tourte watched a video and ruled Draper was guilty of interference, awarding the point to his opponent.

Broader Adoption

This technology are not exclusive to Grand Slams. The system has been in use at the American major for two years and the Aussie Open this year.

Furthermore, it is becoming more common on the WTA circuit, and by the coming year the men's ATP Tour plans to have video reviews implemented at every one of its tournaments.

Additional Innovations

A further change at Wimbledon this year involves the addition of graphical cues on displays to support the verbal announcements from the electronic line calling system.

This addresses instances where spectators have sometimes been unsure whether a ball was out or in.

Finally, with exactly a century of days to go until the start of the tournament, organizers have further announced an expansion in daily attendance at the qualifying competition in Roehampton.
