British No 1 Jack Draper began his US Open campaign with a battling four-set win over qualifier Federico Agustin Gomez.
The 23-year-old enjoyed a breakout run in New York last year, reaching a maiden grand slam semi-final and losing to eventual champion Jannik Sinner, and is among the favourites for a deep run this year - and to challenge the likes of Sinner and 2022 champion Carlos Alcaraz.
