14:30 CET - Good afternoon and welcome back to our coverage of the US Open, and by the end of play today, we will know all our last-16 matchups!
It all gets underway at 17:00 CET, with last year's finalist Amanda Anisimova kicking off proceedings on Louis Armstrong, with a potentially tricky test against Anastasia Potapova.
On Grandstand, Australian Open champion Madison Keys faces the resurgent Olympic champion Qinwen Zheng, who had to come through qualifying to get to this position.
Fellow American Taylor Fritz is on Arthur Ashe at 17:30 CET, taking on Francisco Cerundolo. The former has looked imperious so far as he hunts his maiden Grand Slam.
Former champion Coco Gauff takes to court after Fritz with a clash against Cristina Bucsa, while the night session sees a mouthwatering contest between young guns and close friends Alexandra Eala and Iva Jovic.
The atmosphere will be electric, with Eala drawing a huge Filipino following wherever she goes and the Americans bound to be behind Jovic.
Finally, on Arthur Ashe, top seed Alexander Zverev continues his late-night conquest against Alejandro Tabilo, and he will be desperate to avoid a 2am finish for a third time in a row.
Following Anisimova on Louis Armstrong, fifth seed Flavio Cobolli has a very tough opponent in Alexander Blockx, and the Italian will have to raise his level if he wants to get past the Belgian.
Two-time champion Naomi Osaka then comes up against the difficult Elise Mertens, while another face-off between young stars, Jakub Mensik and Learner Tien, rounds off play.
Six-time Grand Slam champion Iga Swiatek will meet Marie Bouzkova on Grandstand, while Elena Rybakina will be hoping her injury issues stay behind her against Yulia Starodubtseva. The Ukrainian stunned Rybakina in the second round of Roland Garros earlier this year.
French Open champion Mirra Andreeva, Karen Khachanov, Zizou Bergs and Luciano Darderi are other names aiming to reach the fourth round.
