On Louis Armstrong, 2016 champ Stan Wawrinka is in action against Italy’s Paolo Lorenzi, who’s hoping to match his best-ever
US Open (and slam) performance by reaching the fourth round. 34-year-old Wawrinka is used to being the veteran, but he’s actually three years younger than Lorenzi. Still on serve in the first set. 8.40pm BST
Those three victories mean the bottom half of the women’s fourth-round draw is taking shape. Konta will face the No 3 seed, Karolina Pliskova, next. Williams and Barty, meanwhile, are on course for a box-office quarter-final meeting.
