No.24 seed Petra Martic, who will play Danielle Collins, is the only player in the lower half of the draw to win two three-set battles to reach the third round. She has come from a set down to win against Jennifer Brady and Anastasia Potapova.
Elina Svitolina is aiming to reach the second week of Wimbledon for the second time in her career. Her opponent, Maria Sakkari, has never been beyond round three.
Karolina Muchova has happy recent memories of facing Anett Kontaveit: she defeated the No.20 seed in the first round of the French Open a matter of weeks ago, 3-6, 6-2, 6-2.
No.3 seed Karolina Pliskova lost her previous meeting against Hsieh Su-wei on Dubai’s hard courts earlier this year. She had won the pair’s only other encounter, but both have been tight three-set matches.
Simona Halep and Victoria Azarenka have a 2-2 career head-to-head record. The WTA World No.7, however, has won each of the last two, which were both at majors, with the latest a 7-6(3), 6-2 win at 2017 Wimbledon.
Polona Hercog is the latest player to face the Cori Gauff phenomenon. If the Slovenian beats the 15-year-old, she will reach the second week of a Grand Slam for the first time in her career.
No player in the bottom half of the draw has dropped fewer games to reach this stage of the competition than Zhang Shuai, who has squandered only nine.
No.14 seed Caroline Wozniacki has a 1-1 career head-to-head record with the Chinese player, losing their previous meeting at Indian Wells in 2016, 4-6, 7-6(8), 7-5.
Danaya Yastremska’s match-up against Viktorija Golubic is one of only two third round ties that do not feature a seeded player. The other is Gauff vs. Hercog.
