Joel: My heart stopped a few times in that last game.
Konta 7-5 5-5 Vikhlyantseva*
Well, Natalia Vikhlyantseva is visibly frustrated after missing those two set points.
She drops two points before scrambling back to 30-30, Konta wraps a return from a low-bouncing serve into the bottom of the net only for Vikhlyantseva to crack the net off the next.
She squats in disbelief.
BBC Red Button
If you want to watch Kyle Edmund v Alex Bolt on the telly, then press the red button.
There's a whole host of Brits in action, plus Delpo, Kyrgios and Nishikori. Make your choice from 16 streams here.
Edmund 0-0 Bolt*
Right, it'll be Australia's Alex Bolt to serve first.
Warm applause for Kyle Edmund as he makes his way out onto court.
Muguruza v Broady
Tracy Austin
Two-time Grand Slam champion on BBC TV
This is a big day for Naomi - one she has probably dreamed of all her life. You are playing the defending champion on Centre Court and it is a very special moment.
You want to play well and maybe cause a shock but you also don't want to get wiped out.
So many Brits, so little time...
Konta 7-5 5-5 Vikhlyantseva*
Jo Durie
Former British number one on BBC TV
A huge sense of relief for Konta to squeak out of that game. She is a fighter, got into a spot of bother but fought her way out of it.
Edmund v Bolt
Konta 7-5 5-5 Vikhlyantseva*
First serve rattles the net from Johanna Konta, second goes to the Natalia Vikhlyantseva backhand and the Russian steams it back with too much purchase.
She's shaking her head. Two set point chances missed.
Vikhlyantseva sends another backhand long, and then cracks the net with a stretching forehand.
Konta, somehow, staves off two set points to hold.
*Konta 7-5 4-5 Vikhlyantseva
Wide! Johanna Konta pushes the Russian way out west and Natalia Vikhlyantseva can't pull her forehand back towards the good stuff.
Konta survives set point.
But then gifts the 21-year-old another...
*Konta 7-5 4-5 Vikhlyantseva
Off balance and back-pedalling, Johanna Konta sticks a forehand into the tramlines.
Natalia Vikhlyantseva meets a running Konta forehand with a whipping backhand and now has set point.
*Konta 7-5 4-5 Vikhlyantseva
How about that to settle the nerves? Johanna Konta serves her fifth ace of the match at a time of need and follows up with another corker that Natalia Vikhlyantseva can't muster back.
That 0-30 quickly turns to 40-30.

Jo Durie
Former British number one on BBC TV
Konta was coasting, but Vikhlyantseva is a dangerous player. She's a big hitter, her serve in the last game was booming, puts pressure right back the other end. A couple points can turn a set.
Konta needs to take a few deep breathes get herself together. It is going with serve now, so she shouldn't panic.
*Konta 7-5 4-5 Vikhlyantseva
So having been a break up, Johanna Konta finds herself serving to stay in the second set.
Natalia Vikhlyantseva pops a fizzing return in to take an early lead in the game, and then polishes off a neat winner after Konta flops in a terrible drop shot to mid-court.
0-30.
And on court one...
Barty 7-5 6-3 Voegele
Ash Barty makes two from two for Australia's women today.
She beats Stefanie Voegele in straight sets and will face either Britain's Gabriella Taylor or Canada's Eugenie Bouchard next.
Sam Stosur has also taken the first set 6-4 against Peng Shuai.
Sonia Oxley
BBC Sport at Wimbledon
Is Konta having a wobble? She had looked completely in control of this second set. Confidence is not her strong suit at the moment - and Vikhlyantseva seems boosted by that break. Will Konta keep her cool? She is serving to stay in the set.
Strictly Come Dancing host Tess Daly and her husband Vernon Kay are enjoying the Royal Box hospitality and settling down to watch a day's tennis.
Actors Charles Dance and Joely Richardson are in attendance too, as is former news reader Sir Trevor McDonald and the BBC's very own cricket correspondent Jonathan Agnew and his wife Emma.
*Konta 7-5 4-5 Vikhlyantseva
Jo Durie
Former British number one on BBC TV
I don't know where that came from, that was a sudden switch. Konta gave a few away points, two unforced errors in the game. It has given Vikhlyantseva a lot of confidence.
*Konta 7-5 4-5 Vikhlyantseva
Natalia Vikhlyantseva is looking evidently more confident after garnering that break back.
She steams down a string of sizzling serves to rattle Johanna Konta, who challenges a wayward return only to find it's a good racquet-length long.
Vikhlyantseva holds.
