Bengaluru: World No. 5 Karolina Pliskova lost her cool over a line call and bashed a hole into the umpire's chair with her racket after suffering a 3-6, 6-3, 7-5 defeat by Maria Sakkari in the Italian Open second round on Wednesday.
Pliskova had argued heatedly with umpire Marta Mrozinska after her smash was called out when serving at 40-40 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 before approaching Mrozinska with an outstretched hand before withdrawing it and repeatedly smashing the chair with her racquet.
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.
