The women's semi-finals will now take place ahead of the men's after rain washed out Thursday's action at the US Open.

Play will get underway on the Arther Ashe Stadium at 11am (4pm GMT) as Italian Flavia Penetta looks to reach a first Grand Slam final when she takes on No 2 seed Simona Halep of Romania. Immediately after, Serena Williams will continue her bid for a calendar Grand Slam when she takes on another Italian in Roberta Vinci.

Once the women's semi-finals are complete, the men will take to the showcase court at Flushing Meadows as World No 1 Novak Djokovic faces No 9 seed Marin Cilic, before an all-Swiss affair sees Stanislas Wawrinka take on Roger Federer for a place in the final.
