At 4-4, game point for Pavlyuchenkova, Kartal went long. At least Pavlyuchenkova seemed to think so, but in the absence of any call from Hawk-Eye, confusion rippled through the court. Umpire Nico Helwerth subsequently announced, 'The electronic line-calling system unfortunately was unable to track the last point so we will replay the point.' This led to groans from commentators and jeers from the crowd, as it was clear that Kartal's shot was out.

The ABS system permits each team two challenges per game that are retained so long as they are successful.
