With the clay-court surface the only one where electronic line-calling is not yet the standard because of its constantly shifting nature, you know it’s coming sooner rather than later.
And indeed this year, the trials at certain tournaments on the ATP Tour continue. And the tournaments are getting bigger.
Electronic linecalling will be in use on a certain number of courts in Barcelona next week, then in Estoril and finally at the Madrid Masters 1000.
So – one at each ATP level. And all will use FoxTenn.
It will be used on centre court only in Barcelona and Estoril.
In the cases where the electronic line calling is installed, the players will be allowed an unlimited number of challenges (as they would, theoretically, be allowed an unlimited number of requests to the chair umpire to verify the mark).
But once the electronic-line calling verdict comes down, they won’t be able to ask for the line to be checked if they’re not satisfied with the outcome.
After being tested on the Challenger circuit in 2019, the ATP-level trials began in the 2020 season – quickly interrupted by the pandemic. The FoxTenn system, approved for use on clay by the ATP Tour, was used at the Rio 500 tournament that year.
FoxTenn was used in Madrid last year as well; it’s a Spanish company, so it makes sense that two of the review sites are in Spain, the other in nearby Portugal.
