Andy Murray has revealed one of his favourite things about winning Wimbledon was the way it brought his family together.
At the Champions Dinner following his three-set win over Novak Djokovic, Murray was pictured hugging his mother Judy and father Willie.
The Scot's parents separated when he was a child and although they often both attend Murray's matches at grand slams, they never sit together.
Murray said: "My parents got divorced when I was younger so they didn't spend a whole lot of time together. It was just nice to have everyone really happy."
Djokovic and Rafael Nadal are expected to be his main competition in New York, and his slide from two to three in the rankings on the eve of the tournament has made Murray's path more difficult.
Had he stayed at two, he could have been on the other side of the draw to both, but he could well have to beat Djokovic in the semi-finals and Nadal in the final.
Murray's coach, Ivan Lendl, said: "That's a complication, there is no doubt about it. It would be better if Novak and Rafa are in the same half of the draw and Andy is in the other. He just has to deal with it."
Lendl said after Wimbledon that he believed Murray was the best player in the world as the holder of two grand slam titles and an Olympic gold medal but the Scot is very unlikely to be able to challenge for the world number one spot this year, largely because of the form of Nadal.
The trio and Roger Federer have shared the grand slams between them over the past couple of years and Lendl does not expect that pattern to change significantly.
Meanwhile, Li Na and Agnieszka Radwanska beat the rain to reach the second round at a stormy Flushing Meadows.
Third seed Radwanska had a tough second set against Maria-Teresa Torro-Flor but came through 6-0 7-5 while fifth seed Li defeated Sweden's Sofia Arvidsson 6-2 6-2.
Dark clouds were gathering before the pair were off court, and not long afterwards play was suspended because of the threat of lightning.
Soon heavy rain was falling, and organisers announced that there would be no play before 2.30pm local time.
Li said: "I was so lucky before the rain came that I finished the match so I don't have to wait and warm up and come to the court again.
"For me, I'll just relax for the rest of the day and do whatever I want to do."
Li could play 30th seed Laura Robson in the third round in a repeat of last year's clash at the same stage, which was won by the British teenager.
Robson was just about to start her clash with France's Caroline Garcia when play was stopped.
