ROME • It is probably safe to say that umpire Marta Mrozinska is persona non grata at the Pliskova family household after a poor line call at a critical juncture led to Karolina losing her cool on Wednesday.
The world No. 5 bashed a hole into the umpire's chair with her racket after suffering a 3-6, 6-3, 7-5 second-round defeat by Maria Sakkari in the Italian Open.
Pliskova had argued heatedly with Mrozinska after her smash was called out when serving at 30-30 and 5-5 in the final set, and her Greek opponent won the game before serving out the match.
The Czech exchanged a brief word with Sakkari at the net and then approached Mrozinska with an outstretched hand only to withdraw it.
She then repeatedly smashed the chair with her racket.
Pliskova's twin sister Kristyna, who also ranks in the world's top 100, slammed Mrozinska on social media.
"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," the 26-year-old wrote on Twitter.
And yesterday, Romanian Simona Halep moved one step closer to staying as world No. 1 after being handed a walkover into the quarter-finals of the tournament after American Madison Keys withdrew due to a rib injury.
Halep needs to reach at least the last eight and go further than second-ranked Caroline Wozniacki of Denmark to retain the top ranking going into the French Open.
