Melbourne, Jan 20, 2018 (AFP) - - Karolina Pliskova outmuscled fellow Czech Lucie Safarova to make the Australian Open fourth round on Saturday in a testing two-set encounter.
The tattooed sixth seed, looking to win her first Grand Slam, came through the tight match on Margaret Court Arena against her 29th seeded compatriot 7-6 (8/6), 7-5 in 1hr 37mins.
"It was a tough match, it always is against Lucie," said Pliskova, who made the quarter-finals last year.
"I'm happy I held my serve in the last game, It's a good sign because my serve is the most important key for me."
She will next play either American Bernarda Pera or another Czech Barbora Strycova who clash later.
