Maria Sakkari has secured her spot in the fourth round of the Australian Open, defeating No.10 seed Madison Keys, 6-4, 6-4.

It is the first time in her career that the 24-year-old has made it into the second week of a major tournament.

“I have been struggling a lot at every Grand Slam,” Sakkari said post-match. “I was getting stuck at the third round, so I’m so happy to be through to the fourth round! It was a great day for me, and a great crowd.”

It was also the first time Sakkari and the American had played one another, with the young Greek taking one hour and 15 minutes to take out the win on Margaret Court Arena.

Sakkari will next play 2019 runner-up Petra Kvitova from the Czech Republic.
