Overview
- The match, postponed from Sunday, began on Monday but was suspended after nine points when rain returned and play resumed later the same day.
- Argentina’s Mariano Navone beat Matteo Berrettini in three sets, 3-6, 7-6, 3-6, to advance to the second round and set up a meeting with Valentin Vacherot.
- Berrettini started the match strongly but lost momentum after multiple breaks in the third set as Navone secured the decisive early break.
- Reports note Berrettini has been managing chronic hip pain since Wimbledon and is still scheduled to compete in the Cincinnati Masters as part of his US Open build-up.
- Their prior head‑to‑head was 3-0 for Berrettini but all those wins came on clay, making this first hard‑court meeting a notable factor in the upset and in his North American swing plans.
