Enraged by a line call that had gone against her at a key moment, Pliskova sensationally reacted to losing her match against Maria Sakkari by repeatedly striking the umpire's chair with her racquet, making a hole in the process.
The decision prompted fury from fans online, some calling for the umpire to be removed from their position, whilst some claimed Pliskova went too far in her actions.
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.

A champion in Indian Wells earlier this year, Osaka has recorded a number of notable wins in a breakthrough year on the WTA Tour.
The Czech was locked at a set all, 5-5, and 40-40 in her already-tense second round match against the world number 42 Sakkari in Rome. "It's tough to make winners on this court, for me, but it's good when I can build the point". The 27-year-old Dane, chasing her first claycourt title since 2011, will face 15th seed Anastasija Sevastova for a place in the quarter-finals. Gavrilova recovered from 4-0 down in the third set to beat world number three Muguruza 5-7, 6-2 7-6 (6) in just over three hours.
