Linespeople will be redundant in the run-up to the US Open after Monday’s announcement that all line-calling decisions will be made electronically.

The US Open series is due to utilise the Hawk-Eye system, officials said, eliminating the human element along the sidelines.

The system, which was successfully used last September in the COVID-edition Open and the preceding “Cincinnati” event – organisers claim 314,000 calls were made between the two tournament – will be in place all summer long at seven of nine ATP, WTA and joint events to include:

Atlanta, Washington, D.C, Toronto, Montreal, Cincinnati, Winston-Salem and a new WTA 250 in Cleveland.

Only a new ATP 250 in Los Cabos, Mexico and the WTA 500 series in San Jose appear to be out of the technological hardcourt loop.
