Watch: Czech tennis player Pliskova 'smashes' umpire's chair
Former world number-1 Karolina Pliskova, 26, repeatedly hit the umpire's chair with her racket after losing her match to Maria Sakkari in the second round of the Italian Open surprising everyone in the crowd since the Czech player has no history of misbehaviour.
Greece's Maria Sakkari defeated Karolina Pliskova 3-6, 6-3, 7-5 in the second round of the WTA Italian Open, out of frustration, Pliskova furiously hammered the umpire's chair with her racket.
In the third set with the sixth-seeded Czech serving 6-3, 3-6, 5-5 (30/30) she had an overhead shot incorrectly ruled out and both the line judge and the umpire said they could not find the mark.
After vehemently arguing with the umpire to no avail Pliskova became furious as 42nd-ranked Sakkari was given the advantage and also a breakpoint at a crucial stage of the match.
Karolina Pliskova behaviour could attract a heavy penalty even the WTA hasn't announced its decision as yet.
