Brighter times for Kiki
That came on the back of her enforced quarantine in New York but things are finally looking up after the Frenchwoman and partner Timea Babos moved to within one victory of successfully defending their doubles title.
Djokovic closing in
Djokovic has made no secret of the importance of records during the final years of his career, and one of the big ones is now firmly within his grasp. The Serbian is spending his 289th week at world number one – 21 short of Roger Federer's record.
He is guaranteed to hold onto the position whatever happens on Sunday and, with the ATP deciding that coronavirus measures meaning players will not lose ranking points will continue until March, the chances of anyone passing him before he overtakes Federer significantly receded.
Who's up next?
Swiatek and Sofia Kenin take centre stage on Saturday for a youthful women's singles final.
Swiatek, 19, has swept all before her on her way to a maiden slam final, while Australian Open champion Kenin, 21, is bidding to become the first player since Angelique Kerber in 2016 to win two titles in a season.
