Welcome to day four of the 2026 US Open, a tournament day packed with compelling matchups across multiple courts and sessions. Yesterday's rain has created a sprawling schedule that stretches the competition across the grounds, making it difficult to know where to begin covering the action.
The morning session opens with Daniil Medvedev taking the court on Armstrong Stadium. As a former champion, Medvedev will be looking to capitalize on what appears to be an open field in the men's singles draw. Elsewhere, Brandon Nakashima—who surged to the Cincinnati semifinals last month after defeating both Medvedev and Taylor Fritz—faces Alex Michelsen in a match that could prove pivotal for the American's tournament run.
On the women's side, Jessica Pegula takes centre stage on Ashe Stadium against Sofia Kenin. Pegula is chasing both a first Grand Slam title and the world number one ranking, while Kenin has already achieved the latter milestone. This encounter has the potential to develop into a memorable contest between two players with contrasting career trajectories.
According to tournament records, Frances Tiafoe advanced at the 2026 US Open following a five-set victory, adding an upset-flavored result to the opening-round storyline and demonstrating the unpredictability of early-round play.
