Jakub Menšík defeated Gregoire Barrere 6–4, 4–6, 7–6, 6–2 in the first round of the US Open on hard court on 28 August 2023, upsetting the pre-match favourite Barrere. The Czech player recovered from dropping the second set to take control in the third, securing the tie-break before dominating the fourth set to advance. Barrere, seeded higher in the betting odds, could not maintain consistency across the match despite an early break. Menšík's comeback victory suggests momentum heading into the second round.
