But like so much in our world, the French Open and other clay-court tournaments are facing change. Tour-level events held on hardcourts and grass already use electronic line calling in some form, including all three of the other Grand Slam events: the Australian Open, Wimbledon and the United States Open. There are no such marks on grass, and they are much less definitive on hard courts, if they exist at all. FoxTenn, a Spanish line-calling system, has received approval from the men’s and women’s tours for a trial use on clay. Hawk-Eye, long the leading system in tennis, is seeking similar approval, and a version has even been used in some tournaments to eliminate human line judges completely.
