Twenty years since their first meeting at a Grand Slam, sisters Venus and Serena Williams will face each other for a place in the US Open last 16.
The pair meet in the night session, from 00:00 BST, on Arthur Ashe Stadium at Flushing Meadows on Friday.
"At least this time it will be fair," laughed Venus, referring to last year's Australian Open final when Serena was pregnant with daughter Olympia.
"The last time we played [in a Grand Slam] it was two against one."
This will be their 30th meeting - Venus won the 29th at Indian Wells in March - and the earliest they have faced each other at a major since that initial match two decades ago.
