World tennis number five Karolina Pliskova faces a fine or possible suspension after smashing her racket into the umpire's chair following a defeat.

Pliskova was stunned 3-6, 6-3, 7-5 by Maria Sakkari of Greece in the round of 32 at the Rome Masters.

At 5-5 in the third, Pliskova got engaged in a lengthy argument after she had an overhead smash called out.

The chair umpire acknowledged that she "lost" the ball mark and therefore said the point should be awarded to Sakkari. On the next point, Sakkari converted a break then served it out.


After the match, Pliskova didn't shake hands with the chair umpire and struck the chair several times with her racket.
