Some facts about Joao Sousa.
Nadal 6-3 6-1 3-2 Sugita
The Dog and Fox in Wimbledon undoubtedly gets busy during these two weeks, but sadly, for some, you won't see Nick Kyrgios and Rafael Nadal sit down with drinks and natter away about the grass patterns of Court One.
Yes, the Australian who looks set to meet the Spaniard in the second round suggested that they aren't 'besties'.
"Not sure that me and Rafa could go down to the Dog & Fox and have a beer together. I don't know him at all. I know him as a tennis player," said Kyrgios.
"I get along with people, some people I don't get along with.
Nadal accused the world number 43 of "lacking respect" after serving underarm during his defeat in Acapulco this year. Kyrgios described the Spaniard as "super salty".
The Aussie also criticised Nadal's uncle and former coach Toni, who had a go at Kyrgios for his on-court behaviour.

Serena Williams looks a bit puzzled with herself. A couple of times in the last few games, I’ve noticed her shake her head at herself, ever so slightly. At the end of one game, she took a few seconds to herself, closing her eyes to zone out.
On serve, she’s just let out a little scream in frustration. Gatto-Monticone has vastly improved in this second set, and Williams knows it.
*Sousa 2-0 Jubb
Not the start Paul Jubb was hoping for. One service game he has had, once he has been broken.

It's surprising that it's become this competitive. We were all waiting for Serena Williams to step it up and close it out.
So there's cause for concern if you're a Serena fan. She's still working out the rust a little.
Williams 6-2 6-5 *Gatto-Monticone
Serena Williams runs down a drop shot and flicks away a winner to provoke a scream of delight and a double air grab.
A nothing-much shot though allows Guilia Gatto-Monticone to thread the needle down the line for 15-15.
Williams looks non-plussed. But she gets over the line.
And Guilia Gatto-Monticone has to serve to stay in the match once again.
*Sousa 0-0 Jubb
We're under way on court 17 as 19-year-old Paul Jubb aims to become the eighth Briton into the second round. Opponent Joao Sousa starts us off.

Dennis Ethan: Some bad misses by Serena in this match.
*Williams 6-2 5-5 Gatto-Monticone
Serena Williams nearly decapitates a line judge with a vicious overhead to get on the board at 30-15.
Another smash, but this one is loose and lacking in the same power. Straight back to Gatto-Monticone who pins her on her toes. 40-15.
Williams' walloped return brings up 40-30, but she is long in the next rally and somehow Gatto-Monticone is level.
Sharapova (ret) 6-4 6-7 (4-7) 0-5 Parmentier
Sad news for Maria Sharapova fans.
The 2004 champ had to call it a day after the fifth game of the third set citing a wrist problem. The Russian five-time Grand Slam champion had a medical time-out at the start of the decider and never really recovered.
As for Frenchwoman Pauline Parmentier - that was her first win at Wimbledon since 2011.
Tres bien.
Sousa v Jubb
Katie Falkingham
BBC Sport at Wimbledon
Paul Jubb will be pinching himself today. After training adjacent to Novak Djokovic earlier, he's now about to make his Wimbledon debut at the age of 19.
It's worlds away from the Hull council estate where he was brought up by his grandmother from the age of four after his parents both passed away.
His grandmother, Valerie, is here today - what a proud day it must be for her. I'll see if I can spot her in the crowd.
John McEnroe
Three-time Wimbledon singles champion on BBC TV
Serena Williams have been consistently first serving at 110-115mph - which is pretty good but we know she's capable of more.
It's going to be about her movement and how she recovers between points against the better opponents.
Williams 6-2 5-4 *Gatto-Monticone
Despite the scoreline, all is not right with Serena Williams.
When she is on the move, she does not look comfortable. The American is also leaking points with unforced errors.
One such mistake, a backhand volley biffed long, costs Williams the game and a return to the locker room.

Jena: I don't think Serena will be able to come to net like this against Halep or Kerber!
*Williams 6-2 5-3 Gatto-Monticone
Guilia Gatton-Monticone is hanging well in the rallies, but Serena Williams' power eventually ends her resistance.
The American will serve for the match next.
Nadal 6-3 5-1 2-0 Sugita*
... Nick Kyrgios.
That match will be on Thursday.
Williams 6-2 4-3 *Gatto-Monticone
Guilia Gatto-Monticone has a funny hooky, halty take-back in her service action.
It is a little funky, but nothing that Serena cannot groove to
The American clouts away a backhand volley to move to 30-30.
Williams can't convert a break point. To deuce.
Sam Smith
Former British number one on BBC TV at Wimbledon
I sometimes wonder how Serena Williams copes when she's playing at this level, because she knows how much better she can be.
It must be a difficult thing to manage.
Williams 6-2 4-3 *Gatto-Monticone
Guilia Gatto-Monticone beware!
Well placed at 30-30, the Italian sees Serena Williams rip a 119mph ace through the T and celebrate with a bellow of celebration.
Next point, Serena lands a whopping great ace out wide and screams 'Cmon!'.
Something is brewing. It could be a break of Gatto-Monticone's serve.
