The big talking point at Flushing Meadows on Thursday centred around a conversation between Nick Kyrgios and umpire Mohamed Lahyani during the Australian’s second-round victory over Pierre-Hugues Herbert.

Lahyani came down from his chair and is said to have encouraged Kyrgios to show more effort when he was a set and a break down.

The umpire has been strongly criticised, including by Herbert, and tournament organisers continue to investigate.

Elsewhere, Roger Federer, Novak Djokovic and Maria Sharapova reached the third round, but second seed Caroline Wozniacki was beaten by Lesia Tsurenko.

There has been no shortage of drama at Flushing Meadows so far, very little of it to do with tennis.

This has been a tournament of goodbyes for an unusually high number of players.

Both David Ferrer and Mikhail Youzhny played their final Grand Slam before retirement, while for Gilles Muller, Florian Mayer and now Julien Benneteau, New York was the end of the road.

Frenchman Benneateau, 36, lost to Jan-Lennard Struff in the second round and will concentrate on his new role as France’s Fed Cup captain.

He said: “I don’t really realise I think. Maybe it’s a little bit too early. Maybe it will take some time to absorb it and to have more emotions.”

As well as goodbyes, there's also been plenty of fashion drama.

Serena Williams' catsuit first and foremost, which was then followed up with Alize Cornet's decision to take her shirt off mid-match after noticing it was on the wrong way round.

Rising temperatures have also been severely discussed due to players struggling with the heat, but Kyrgios' latest actions is the current saga unfolding in America.

One person who has reacted to the drama, and someone who isn't best pleased about it is Federer - the man who is playing Kyrgios next.

With regards to the incident, Federer said: "It's not the umpire's role to go down from the chair.

"I get what he was trying to do. He behaves the way he behaves and then you decide if you like it or you don't like it. I don't know what he said, I don't care what he said. It was not just about how you're feeling, "Oh, I am not feeling well".

"That's why it won't happen again and everybody knows that.

"It's not the umpire's role to go down from the chair. You don't go and speak like that."
