US Open 2024 day one: Gauff and Zheng advance, GB’s Choinski falls in decider after five sets – as it happened

Coco Gauff began her title defence with an emphatic win while the Olympic champion Zheng Qinwen was forced to come from behind in the first round

*Choinski 1-2 Carballes Baena (denotes server): Choinski is such a strong server and because of the hardcourt they are quite speedy as well. It means that Carballes Baena is opting to stay so far back to recieve. He is well outside of the court lines and often times out of the camera frame as well. Choinski gets the advantage but Carballes Baena slowly moves up the court and hits a smashing forehand to make it a second deuce. We go back and forth for a while but it's at the sixth break point where after a short rally the Brit hits a shot out. That 13-minute felt never ending and had everything: foot faults, a few aces and some slicing shots.

Choinski 1-2 Carballes Baena* (denotes server): On Court 16, Carballes Baena is leading by a game against Choinski. This match has been a lot more free-flowing but the unforced errors for both are mounting up. Think this might be a battle of who can hold their nerve better.
