McEnroe shares why Nick Kyrgios didn't play Laver Cup on Sunday

In a press conference, the Team World Vice-Captain Patrick McEnroe spoke about the reasons why Nick Kyrgios did not play the second singles match on Sunday at the Laver Cup in Geneva.

McEnroe said: "Nick has had a little bit of a shoulder issue coming in.

Obviously he was able to play quite well yesterday (Saturday), but I think the amount of tennis he played yesterday just came up this morning, he was feeling something in his shoulder that had been bothering him but not significantly.

So significantly it was this morning. Tried to warm up twice two different times, and was pretty obvious that he wasn't going to be able to go full out.

That's when we knew we had to make a change.

Unfortunately, you know, the rules that are in place did not allow us to make the sort of changes that we would have preferred to make, because since it was our turn on Sunday to match up against their players, we were basically denied that once the schedule was put out.

So once Nadal just pulled out, our options were limited.

We would have put Shapovalov in as our next player, but because he was matched up against Thiem, we were not allowed to do that.

That was the reason for our protests that we decided to wait a little bit before we left the locker room because we don't think that's fair."

One of the best moments for Nick Kyrgios at the Laver Cup in Geneva was the doubles match on Saturday with Jack Sock against Rafael Nadal and Stefanos Tsitsipas.

The Australian player said: "When you're playing Roger or Rafa in doubles, the other person is usually the weaker point. But I thought me and Jack came out strong. We played really, really well. Stefanos returned well.

I thought he played well today. Honestly, he served well. Especially to Jack, I thought he served well. Yeah, I mean, he was solid.

His returns were going in. I thought it was a high-quality doubles match. Me and Jack, obviously we have played three times and haven't lost.

Our chemistry is pretty high." Nadal added:

"Honestly, we were close. Even if the score was 9-4 at some point, between 4-All and 8-4, we lost a couple of points that could go both ways. No, no, I think we played with the right intensity.

We played with the right energy that moments. Just we have good players in front that they want to win, too, and they are good. They are talented.

They know how to play doubles. That's it. Just congratulate them." Europe defended its title against World after Alexander Zverev won against Milos Raonic in the final singles match on Sunday.

Earlier, Dominic Thiem and the doubles team of Federer-Tsitsipas lost their respective matches.

Federer defeated John Isner in the second singles match to put Europe in contention for the title, again after World had taken a lead for the first time in the tournament's history.
