The tennis sisters Serena Williams and Venus Williams hit the virtual court today ahead of the U.S. Open next week.

World number one Serena Williams and her sixth-ranked sister Venus warmed up for the U.S. Open next week by going head-to-head in a game of virtual tennis on Thursday.

The Williams sisters played 'Virtua Tennis' using motion sensing plastic racquets in front of a large video screen at the Lotte New York Palace Hotel.

Spain's Rafa Nadal, 14-times a grand slam champion, also took part on the miniature court, playing with the hotel manager.

The U.S. Open starts at Flushing Meadows on Monday.
