A women's doubles match between Venus and Serena Williams will be the highlight of the
fourth day of the US Open. It will feature the Czech duo Lucie Hradecka/Linda Noskova.
Before we move on to the evening session, however, World No. 1 Iga Swaitek
opens Centre Court on Day Four when she faces Sloane Stephens (2017 US Open champion),
in a contest that starts at 17:00 BST.
Jessica Pegula, World No 32 Aliaksandra Snovich, will also be on the Louis Armstrong court.
