The order of play for day four of the US Open has been released as organisers struggle to cope with rain delays in New York.
Day three suffered from the weather meaning that many of the women's second-round matches were pushed back a day in an effort to cope with the pile-up.
As a result, play will start slightly earlier on day four at Flushing Meadows. Below is the order of play for the showcase courts.
3pm: Sara Errani vs. Flavia Pennetta
Not before 5pm: Serena Williams vs. Galina Voskoboeva, Roger Federer vs. Carlos Berlocq
