Karolina Pliskova to miss Australian Open

A frustrated Karolina Pliskova clashed with the chair umpire and blew a 5-0 lead in the second set to go down 5-7, 5-7 to Czech compatriot Karolina Muchova in the third round of the Australian Open on Saturday.

The sixth seed, who later said she never got into her comfort zone, received a code violation for racquet abuse during the opening set.

Pliskova then left the court at the change of sets. An official had caught Pliskova smashing another racquet while off court, telling the chair umpire when she got back.

When given another code violation, which resulted in a point penalty, the statuesque Czech lost her cool.

“I can do what I want off court!” Pliskova told the chair umpire.

The umpire replied: “Yes, but you’re still not allowed to do it.”

Pliskova shot back: “Why not? Off-court I can do what I want!”

The exchange though seemed to have fired up the 28-year-old. She won five games in a row and looked like she would stage a comeback.

“There was long game for 5-1 and 6-0. I thought she just played little bit better at this moment,” Pliskova said after the match. “Of course, I played quite amazing to 5-0, but then it’s quite tough to hold this level.”
