Hawk-Eye to replace line judges at ATP Next Gen Finals
Line judges will be replaced by Hawk-Eye at the Next Gen Finals in Milan later this year, the ATP has confirmed.
The technology was first used at an elite-level tournament in 2006, and allows players to challenge calls via video replays.
It has previously been in operation in tandem with line judges, but those officials will not be present at the tournament in Italy in November.
Instead, the chair umpire will be the only official on court, as 'Hawk-Eye Live' will make instantaneous in or out decisions, which will be final and not subject to review.
"This could be a landmark moment for officiating in our sport," said Gayle David Bradshaw, the executive vice president of rules and competition at the ATP.
"Our athletes work incredibly hard and they deserve the very best and most accurate officiating we can offer.
"The technology is now in a place where we feel comfortable trialling this new system in a real tournament environment.
"The Next Gen ATP Finals in Milan is the perfect place to do this, and we look forward to monitoring the results and assessing the merits of this new system."
Earlier this year, it was announced the Next Gen Finals would also trial shorter sets as well as a reduced warm-up time and a shot clock.
