Andy Murray rolled back the years as he agonisingly lost out to third seed Stefanos Tsitsipas on a sensational opening day at the US Open.
The former world number one pushed Tsitsipas all the way in a five-set marathon, but was left frustrated by the Greek's lengthy bathroom breaks and made his feelings clear afterwards.
It was a tough day for the British contingent with only Dan Evans making it through.
Meanwhile, Naomi Osaka got her title defence up and running with a 6-4 6-1 win over Marie Bouzkova.
Here, the PA news agency looks back at day one at the US Open.

Murray's defeat was quickly followed by Cameron Norrie going down in straight sets to Spanish teenager Carlos Alcaraz. Johanna Konta's withdrawal through injury pre-empted a miserable day for Britain's women with Heather Watson and Harriet Dart departing. But Dan Evans made it through, beating Brazil's Thiago Monteiro 6-3 7-6 (6) 6-4 6-1.
