Despite TV replays proving Pliskova's shot was in, HawkEye and the challenge system isn't used on clay so the chair and line umpires rely on ball marks to settle disputes. The point happened in the final set when Pliskova was serving a 30-30 and five games all.
After Pliskova embraced Sakkari at the net, she went to shake the chair umpire's hand before pulling it back and smashing her racket several times into the umpire's chair, clearly surprising Sakkari and leaving a massive crater in the chair.

This led to the Czech star to lose the match against Greece's Sakkari 3-6, 6-3, 7-5 and when the players walked off court the No.6 seed decided against shaking hands with Polish umpire Marta Mrozinska. Immediately afterwards, she proceeded to repeatedly strike the umpire's chair to drill a hole in it and then threw away the racquet in frustration.
Her twin sister, the 71st ranked Kristyna also became a part of the controversy after she bashed the umpire and WTA on Twitter.
