Kerber 4-6 6-6 (0-1) Rogers*
It's Kerber to open the tie-break, but it's Rogers who snaffles the point as the ball slides off the top of the net and over!
*Kerber 4-6 6-6 Rogers
Rogers is 40-15 to the good. Are we heading for a tie-break? Oooh, perhaps not. The American nets and then plants a drop shot out. Deuce.
A rally ensues - 15 shots in total - and Rogers wins the battle of the big hits to take the advantage.
On her second serve, she tracks back to watch Kerber's shot drop long.
We will have a tie-break! Exciting.
Radwanska 3-6 6-4 Bacsinszky
One set all on Centre then as Agnieszka Radwanska overpowers Timea Bacsinszky with a backhand down the line.
The crowd are loving this. Bacsinszky calls for the trainer during the break. She is complaining of - I think - a slight ankle problem. Tape it up.
Radwanska 3-6 5-4 Bacsinszky
Radwanska will come out from this drinks break to serve for the second set. She hasn't got the biggest serve but when she does land a first serve - which she is doing 72% of the time in this set - she wins 62% of points. Big.

At this stage of the match, the subtleties are just so small. Rogers needs to intimidate a little bit more when she gets the opportunity on Kerber's second serve.
Kerber 4-6 6-5 Rogers*
Angelique Kerber looks annoyed at herself after a shaky couple of serves.
Rogers adopts a similar face when she overcooks a forehand, and then Kerber looks even more tetchy when she nets.
Errors everywhere.
We get into a rally and Rogers wins it with a bit of help from the net cord.
After deuce, the advantage goes to Kerber and she holds when Rogers fails to clear with a forehand.

Told you she had fight. With her Wimbledon future and number one ranking on the line, Angie Kerber is back in business.
That was only her second break point and the first since one in the fourth game of the opener.
The crowd aren't having a post-lunch either. They are bang up for a decider.
*Kerber 4-6 5-5 Rogers
Rogers looks like she's about to hold to love before Kerber sends an accurate return on the line.
But the American doesn't hang about. On the next point, the game is hers. Parity restored.
Watch Gael Monfils pull off a twirling trick shot only to lose the point to Adrian Mannarino in the first set of their all French tie.

It seems everyone is in good spirits on the practice courts today!
Andy Murray is out practicing his serves and has been showing off his silky skills with it.
The odd keepy-uppy and a volley over the net gets the seal of approval from Marcus Willis who is watching on with his family.

This women's draw is such a mystery and the women's world number one Angelique Kerber is such a mystery as well.
Kerber 4-6 5-4 Rogers
Rogers isn't bothered by what's just happened. She casually smacks a winner down the line for 0-15. A brilliant take.
Kerber recovers to 30-15 and after another satisfying rally, but the American responds by coming forward and forehands into the empty green grass.
The world number one needs to see this one out...and she does. Kerber leads 5-4 and Rogers needs to serve to stay in the set.

French Open champ Jelena Ostapenko is having a bit of a laugh on the practice court.
Her training partner successfully smashes the ball up into the clubhouse, where an onlooker catches it.
He lobs it back out and yells for Ostapenko to have a go. Her effort isn't even close and gets nowhere near the balcony, much to the amusement of everyone around.
Watch Milos Raonic pull off an incredible backhand cross-court winner at the start of the second set in his third round tie with Albert Ramos-Vinolas.

Angelique Kerber is a fighter, there was a fist pump after that winner in the last game. You don't get to number one by letting tough points go.
Riske 2-6 4-6 Vandeweghe
The list of potential winners on the women's side is basically anyone left in, but here's another name to hurl into the mixer.
Coco Vandeweghe has not dropped a set yet and has made serene progress again, seeing off fellow American Alison Riske in 74 minutes.
The New Yorker hit 23 winners to RIske's five. Ouch.
She plays Caroline Wozniacki or Anett Kontaveit in the next round.
*Kerber 4-6 4-4 Rogers
We're poised at 30-30. This is tense.
The crowd erupts with delight after a sensational rally, in which Kerber looks like she's on the back foot but she comes in to the net and volleys into the corner.
Break point for the top seed.
The German lets out a roar as she watches Rogers' shot go past the baseline.
Gael Monfils swivels and directs a clever backhand right into the back corner of the court against his French compatriot Mannarino.

You get the feeling that one break won't be enough in this set for Rogers, she needs to get that second break.
