Top seeds Jannik Sinner and Iga Swiatek have tricky U.S. Open quarter-final matches against Daniil Medvedev and Jessica Pegula, respectively, in what promises to be an entertaining night session at Arthur Ashe Stadium on Wednesday.
The day session begins with Beatriz Haddad Maia searching for a first victory over unseeded Karolina Muchova, who has won their previous three meetings.
Haddad Maia is also looking to become the first Brazilian woman in 56 years to reach the semis.
