Karolina Pliskova loses her cool during loss to Maria Sakkari in Rome

Karolina Pliskova smashed a hole in the umpire’s chair in anger after a contentious line call late in her loss to Maria Sakkari in the second round of the Italian Open.

The sixth seed was tied at 5-5 in the deciding set with her Greek opponent when her smash was called out by a line judge.

Replays showed the ball landed inside the sideline but umpire Marta Mrozinska refused to accept Pliskova’s pleadings to overturn the call.

Pliskova’s twin sister Kristyna, who is also a professional player, subsequently tweeted: “The worst i have ever seen @wta and i hope this lady Marta Mrozinska will never ever judge any match of me or Karolina again #blacklistforever”
