Serena Williams will get an extra day of rest after her match was scrubbed from Wednesday's schedule at the rainy US Open.
After a rain delay ate up most of the afternoon, tournament officials postponed eight women's singles matches but kept others on the slate, including the night session involving defending men's champion Andy Murray and American Sloane Stephens.
In addition to Serena Williams' match against Galina Voskoboeva, officials postponed matches involving No. 8 Angelique Kerber, No. 9 Jelena Jankovic and No. 25 Kaia Kanepi.
