US Open tennis: Alcaraz, Sabalenka, Pegula and Medvedev advance on day six – as it happened

Defending champions Carlos Alcaraz and Aryna Sabalenka progressed alongside other top seeds in Friday's third-round matches

Leylah Fernandez has broken Pegula early, taking a 2-0 lead in the first. You might recall that Fernandez was Emma Raducanu's opponent in the 2021 US Open final; since losing that match, the Canadian has only gone past the third round at a slam once (the 2022 French Open, where she made the quarter-finals) but has won five WTA Tour titles and is a consistent presence in the world's top 30. So which career path would you prefer: hers or Raducanu's?

Sabalenka takes the first set 6-3, remaining dominant against an opponent who is playing decent stuff. Marta Kostyuk also claims the first set 6-3 over Alexandrova, while Sorana Cirstea has claimed the opener against Paolini by the same score. That feels like an upset, even though Cirstea is seeded higher - No 16 to Paolini's 19.
