Electronic line-calling in Madrid wrong - Rybakina

Elena Rybakina said she did not trust the electronic line-calling system at the Madrid Open following a disputed decision in her three-set win against Zheng Qinwen on Sunday. The Kazakh remonstrated with the umpire after Zheng was awarded an ace for a serve when the Chinese player was 30-0 up and 4-3 down in the second set. Rybakina, who went on to win 4-6 6-4 6-3, pointed to the mark and asked umpire Julie Kjendlie to come down to have a look at it on the clay court, but the official said she could not do so. "The system is wrong, this is not a joke," Rybakina told the official, who said she had to go with the electronic line-calling system. "Well with this thing, I won't trust it at all, because there was no mark even close to what the TV showed."
