Centre Court still alive
Play's not done on Centre Court. Oh no no no.
The organisers have fiddled around with the schedule and American Coco Vandeweghe will take on Kateryna Bondarenko of Ukraine.
They've moved over from court 17, which is a wash out.

Svetlana Kuznetsova, speaking to BBC Two: "It was my first grass win this year. It was a tough first round. I think I did great and I am really happy with my performance.
"Caroline stepped up towards the end, I got a little tense and was rushing it. At 5-4 I said to myself I had to play slow.
"It is my first experience to play with the rood closed and it was really special."

The only place where there is any action right now at Wimbledon is Centre Court where the roof is doing a fine job of keeping the show going.

The rain radar brings bad news.
A dirty great splodge of rain is not shifting from SW19 and so play has been cancelled on all the outside courts.
Cue a rush of brollies to the exits.

A big round of applause. I think these fans would like a longer match. It's been hotly contested - two marquee players and a tough opening round for Wozniacki.

Wozniacki 5-7 1-4 Kuznetsova
A warm applause around Centre Court for Caroline Wozniacki as she gets a game on the board for the first time in this set.
The former world number one has got to the fourth round for the last two years, but she's got a fight on her hands to get over the first hurdle this year.
What's the Wimbledon crowd?

BBC Sport
The capacity in the Wimbledon grounds is 39,000 but Monday's official attendance was 40,403 - a decrease of 2,872 on last year.This is because the official attendance figure includes tickets reused after spectators have left for the day.
It's looking a little sparse now on Centre Court, despite the roof being brought over to protect it from the nasty weather.

Liam Broady is reflecting on his defeat against Andy Murray.
"Even if you think I am just going to focus on hitting the ball, it is still Andy Murray on Centre Court. I think I got better as the match went on," he says.
"Andy said afterwards, 'Good fight well played'. He is a great guy. He asked me as I went off whether I enjoyed it and I said of course I did, I was playing Andy Murray on Centre Court. I didn't enjoy the losing bit."
