With her victory, Serena Williams delays her retirement while Nick Kyrgios defeats Thanasi Kokkinakis on the opening day of the US Open.

It was a nightmare when we both saw the draw, according to Kyrgios.

He thinks Kokkinakis would have defeated 80% of the opposition tonight and is eager to play doubles with him.

"We'll play against one another, hopefully never again."

Serena was being watched by Kyrgios and his girlfriend. He wants to eat right now and relax.

I've eaten plenty for the day and the night, but relaxing sounds wonderful to me.

After a let, Kokkinakis takes some time to bounce the ball.

Kyrgios' lob is just a little bit too long. 4-4.
