The Australian is currently on a 12-match winning streak, having won titles at the French Open and Birmingham in successive weeks, helping her to WTA World No.1.

This will be the first time that the Dutchwoman has faced Minella since 2010. Their head-to-head record stands at 1-1.
Angelique Kerber, the No.5 seed, is defending a major for the third time in her career. In Australia 2017 she reached the fourth round but then later that year at the US Open she fell at the first hurdle.
Tatjana Maria actually beat her compatriot in their only previous meeting, though that was a qualifier on Barcelona’s clay in 2009.
Two-time champion Petra Kvitova might have faced Ons Jabeur in the final of Eastbourne last week but the Tunisian was forced to withdraw from her semifinal injured. They have never previously met.
Sloane Stephens has won her two previous matches against Timea Bacsinszky without dropping a set. The most recent of these was a Fed Cup match earlier this year.

British No.1 Johanna Konta won her only previous meeting with Ana Bogdan in Rabat earlier this year.
Amanda Anisimova may be the No.25 seed, but she has never previously played Wimbledon at senior level, even in qualifying.
