*Bogdan 5-7 2-3 Konta
Johanna Konta gets a little lucky as ball off the frame of her racquet drifts in off a crazy angle for 15-30 on the Bogdan serve.
A more conventional shot sends the ball skipping off the service line to hurry Bogdan into a mistake for 15-40 and two break points.

Saved. The second serve sees Federer try a backhand slice return but he nets. Deuce.
*Harris 6-3 1-6 2-4 Federer
Break point for Federer.

*Harris 6-3 1-6 2-4 Federer
Another game safely overcome for Roger Federer. He needs two more for a two sets to one lead.

Ana Bogdan is playing well here. She's played long enough to feel like she belongs on the big stage and she's making the most of it.
Johanna Konta wouldn't have wanted to get a qualifier in the first round - because Bogdan has already played three matches to get to this stage - whereas Konta might feel a little rusty.

*Bogdan 5-7 2-3 Konta
Johanna Konta's backhand is banging.
The British number one is hitting off that wing like she is seeing a beach ball. A beach ball that she hates.
Two ballistic winners on her way to 30-0.
The forehand is a little twitchier - giving Ana Bogdan a look at 40-30.
But a vicious body serve - zeroing in on the Romanian's diaphragm - gets Konta over the line.
Clarke 4-6 7-5 Rubin
Britain's Jay Clarke lost the opening set to American Noah Rubin but is now serving for the second... and the 20-year-old takes it 7-5!
Elsewhere, Jo-Wilfried Tsonga is two sets up against Bernard Tomic, while in the women's draw 2017 champion Garbine Muguruza trails Brazil's Beatriz Haddad Maia 6-4 2-1.

Away from the show courts, Eugenie Bouchard's match with Tamara Zidansek is drawing plenty of attention.
I took this photo from through some fencing on a stairwell (trying to be arty...!), just to show you how many people are trying to sneak a peek at the 2014 finalist through the gap behind the umpire's chair. Everyone wants a piece of the action!

Francesca Gunn: Watching Roger on my laptop, and Konta on my phone, I don’t know where to look.
Harris 6-3 1-6 2-3 Federer*
Some Hollywood from Lloyd Harris with the inbetweener as he was heading to the baseline, but it only finds Federer waiting at the net, although the South African does go on to take the game.
Bogdan 5-7 2-2 *Konta
Ana Bogdan clumps down her third ace of the match to keep pace up the back straight of the second set.

At the Fed Cup and Davis Cup quite often you see players feel a lot more pressure because they are representing their countries.
It means that when they come back onto the circuit they deal with pressure so much better.
That's what's happened with Johanna Konta in the past few years.
*Harris 6-3 1-6 1-3 Federer
This was when the Lloyd Harris dream start came to a shuddering halt. A break in the second set, with Federer going on to win it 6-1 in 20 minutes.
Federer grabs a break against Harris
*Bogdan 5-7 1-2 Konta
Ana Bogdan cannot keep up pressure. Johanna Konta's serve starts to dictate terms and sees her through.
This is a scrap.
By the way, The Duchess of Cambridge has headed off for the sweets bucket and comfy seats of the Centre Court royal box.
Harris 6-3 1-6 1-2 Federer*
This match is in danger of slipping away from Lloyd Harris very, very quickly.
Federer holds a break point, a forehand from him lands right on the baseline and Harris can only lift one harmlessly in the air. Federer sprints forward and smashes it away at the net for a third-set break.
Image source, EPABogdan 5-7 1-1 *Konta
Johanna Konta is suddenly looking at 30-40 and break point for Ana Bogdan - it is the Romanian's first of the match.
But she wastes it as he plonks into the net disappointingly.
Some superb scampering defence sets up another as she keeps asking Johanna Konta questions and finally leaves the British number one stumped.
Again Konta scrapes it off the table...

Five-time Slam winner and 2004 champ Maria Sharapova is out on Court Two.
The world number 80 is playing French world number 83 Pauline Parmentier.
It's going on serve at the moment.

"Come on Lloyd - you're my hero!"
I suspect the bloke shouting that on Centre Court had never heard of the 22-year-old South African before today...
