Ninth seed Matteo Berrettini battled through an abdominal injury and made it through to the Australian Open fourth round for the first time in his career with a hard-fought 7-6(1) 7-6(5) 7-6(5) success over Russia’s Karen Khachanov on Saturday.
The 24-year-old from Rome is the sixth Italian man in the Open Era to make it to the last 16 of the Australian Open, and next faces Greek fifth seed Stefanos Tsitsipas, who beat Mikael Ymer earlier on Saturday.
Berrettini entered the clash with a clean 3-0 head-to-head record lead over the 19th-seeded Khachanov, with all three of their previous meetings coming in 2019.
Both players showed decent form in the build-up, with Berrettini going 3-1 in singles to guide Italy to the ATP Cup final, after making the quarterfinals in Antalya. Khachanov made the semifinals of the Great Ocean Road Open last week, where he fell in a final-set tiebreak to eventual champion Jannik Sinner.
