And that's it. The US Open is finished for another year.
Novak Djokovic and Naomi Osaka are the 2018 champions.
It's certainly been a memorable one in Flushing Meadows. From Serena Williams' extraordinary row with umpire Carlos Ramos to Rafael Nadal and Dominic Thiem's epic quarter-final match.
History was made in Japan as Osaka and Kei Nishikori reached the semi-finals of the same Grand Slam before the 20-year-old went on to win the women's title - the first Slam victory for a Japanese.
Juan Martin del Potro returned to the big stage but it was a tournament of giant killings as Simona Halep, Angelique Kerber and Venus Williams all fell before the fourth round.
In the end though, it was a stunning men's final which capped things off.
From Matt and I, it's been a pleasure. Catch you next week for more Davis Cup action!

I think most players lose motivation but these players, Nadal, Federer and Djokovic, continue to want to be better and to want challenges.

In five years time we will miss this era. These players are playing a level I have never seen.

Djokovic plays the same sort of style as a lot of the players but is so much tougher. If he is not really focussed and motivated he becomes average.
The intensity required for him is even more so than for someone like Federer.
It is phenomenal that Djokovic is back fit and motivated. I was burnt out after one Grand Slam.

What he has done in the last four or five years with his wrist injuries, coming back and to have faith and belief that one day he will be a top player again. I wish him all the best. I know he will be back here with the Champions trophy."

2018 US Open champion Novak Djokovic: "When I had my surgery I could truly understand what Juan Martin was going through.
"It was a difficult time but you learn from adversity and learn when are down, when things are not working out and I tried to take the best out of myself and thrive on these moments.
"I was hoping he [Pete Sampras] would be here tonight but he's not. I want to say Pete I love you. He's my idol. "

It is hard to see who is going to stop Djokovic in this form.
On clay Rafa naturally but on the other surfaces since he has hit form he has been phenomenal.
