US Open 2026: Pegula, Tiafoe, Shelton and Boulter in action on day four – live

Key events17m agoPreamblePreambleWord up and welcome to the US Open 2026 – day four!And, as you might expect, it’s yet another belter, so much so and – thanks in part to the rain – so, so sprawling, that’s it hard to know where discussion of it can possibly begin.Early doors, we’ve got Daniil Medvedev opening up on Armstrong and, as a former champ, he’ll be eyeing what looks suspiciously like a power vacuum in the men’s competition. Elsewhere, meanwhile, we have a potential epic, the surging Brandon Nakashima – in Cincinatti last month, he reached the last four, beat Medvedev and Taylor Fritz en route – against Alex Michelsen.Jasmine Paolini while, on Ashe, Jessica Pegula – seeking to become world no 1 and win her first major – faces Sofia Kenin, who has already achieved that second dream, in what might develop into a classic. Then, as the afternoon unfolds, we’ve Ben Shelton against Hubie Hurkacz and a match-up that is, indisputably, the stylist’s pick of the day, as Marta Kostyuk faces Sloane Stephens.That is not even close to it. Emma Navarro, back in among it, meets Caty NcNally; Iva Jovic – who is nearing readiness for contention – resumes level at 4-4 with Magdalena Frech; Rafael Jodar returns; so too does Stefanos Tsitsipas, twice a grand slam finalist, whose first-round win over Arthur Fils was his best in a long while; and Katie Boulter must deal with the brilliant Karolina Muchová.And if, to that, we add Jan Choinski, Francesca Jones and Toby Samuel – who takes on Jiri Lehecka – along with Alexander Bublik, Jelena Ostapenko, Mario Berrettini, Alex de Minaur and Andrey Rublev – we have a day of action that feels unparalleled, but for the fact we’ll be back to do it all again tomorrow.Play: 11am local, 4pm BST
