Kristina Mladenovic and Karolina Pliskova have an even head-to-head record, with two wins apiece. The Czech has won both their matches on hard courts on tour in straight sets - in Moscow in 2014, then in Dubai in 2017. Mladenovic's wins came on a hard court in the Fed Cup in 2016, when she edged an epic battle 6-3, 4-6, 16-14; and she also got the win in their only meeting so far on grass, in the 2015 Birmingham semifinal, coming out on top 6-2, 7-6(6).

Belinda Bencic and Anna-Karolina Schmiedlova are also currently level in their meetings so far. The Slovakian won their only meeting on hard court, though, in the Hobart semifinal last year, winning 7-6(2), 4-6, 6-2. Five years previously, the Swiss had also won a semifinal match between the two - on the grass of Eastbourne, 6-3, 6-2.

Donna Vekic and Maria Sharapova have played each other only once before - and that was also in a Grand Slam. The Russian enjoyed a straight-sets win in the second round of the 2018 French Open, 7-5, 6-4.

It will be a second meeting for Jennifer Brady and Simona Halep as well. The American leads their head-to-head after winning in Canada last year, 4-6, 7-5, 7-6(5).

This will be the first meeting not on grass for Ajla Tomljanovic and Anastasija Sevastova. Both their previous encounters have been in Mallorca - in the 2018 quarterfinal, with the Latvian winning 3-6, 6-3, 6-1, and in the 2019 Round of 16, when she won 6-2, 6-1.

Angelique Kerber has never before played the World No.175 Elisabetta Cocciaretto. The 18-year-old Italian is the former junior World No.12, and has come through qualifying in Melbourne to make her Grand Slam main draw debut here.
