Norrie v Schwartzman
Norrie hits one final serve in the warm-up and heads back to his bench.
It's a hazy day in New York today and a pleasant 22C, in case you were wondering.

We would love to be in New York, it won't be quite the same being here in Salford but we're delighted to have Grand Slam tennis back.

The players are settling in - either in one of the two official Long Island hotels, or in a private home, vetted by the US Tennis Association, and with 24-hour security paid out of their own pocket.
If a player leaves the bubble without permission, they will be removed from the competition and fined. To reduce temptation, the USTA has laid on food trucks, an arcade room, a gaming room, and a golf simulator at the hotels.
Norrie v Schwartzman
But before we get into the action, let's chat about life at Flushing Meadows. As you'd expect, things look a bit different this year.
The players are in a bubble but with food trucks and golf simulators to keep them entertained it doesn't look too bad to me.
Norrie v Schwartzman
First up on the agenda for us is Britain's Cameron Norrie against Argentine ninth seed Diego Schwartzman on court five.
