Seismic shocks have been the hot topic in the opening days at Wimbledon.

In the first two days, EIGHT of the top 10 seeded players across the men's and women's singles draws have been eliminated.

That is a record total at any Grand Slam tournament since the start of the Open era, in 1968.

By the end of play on Tuesday, 23 seeds had already been knocked out of the 2025 championships.

Coco Gauff, the French Open champion, became the highest-ranked casualty as she exited alongside fellow women's top-five seeds Jessica Pegula and Zheng Qinwen on Tuesday.

In the men's draw, third seed Alexander Zverev was the fourth top-10 ranked men's player to exit the tournament - making this slam only the third in the past 25 years to see that many top-10 men's seeds lose their opening match.

It's been unpredictable and oh-so engrossing.

The roof is off on Court One. The stands are slowly filling up.

Andrew Castle is commentating. Some supporters are taking selfies. The BBC's Wimbledon theme tune is stuck in my head....

Anyone for tennis?

In a strange twist, Carlos Alcaraz actually started training on court seven before any play on the other outside courts.

Unsurprisingly, the crowds have been massive!

Former British number one Cameron Norrie, is first up on Court One when he takes on American 12th seed Frances Tiafoe from 13:00.

Now, Wimbledon is where super Cam recorded his best ever result at a Grand Slam, reaching the 2022 semi-finals where he was beaten by Novak Djokovic.

But, at the last two editions, he's failed to make it into the second week.

Last year he lost in the third round, albeit in a very tricking draw against Alexander Zverev.

Norrie may be without a title since he lifted the Rio Open in February, 2023, but he can take some heart from his last major where he reached the fourth round of the French Open - his best ever showing at Roland Garros.

After two baking days it has been overcast and drizzly so far. It is still warm, and the heat will no doubt have had an impact on the grass surfaces here at Wimbledon.

Some players have complained that the courts are slower and the ball is bouncing differently.

Wimbledon's head groundsman Neil Stubley feels criticism of the bounce of the ball is unfair, but accepts the high temperatures have had an impact on the speed of the courts, although it would be barely noticeable to the average person.

He told BBC Sport: "I think you probably will see the ball a little slower and I think the reason for that is probably where the [grass] leaf is drying out a bit more, the ball is gripping the leaf a little bit more.

"You and I, we might not notice that but when you are a top athlete you will see those nuances where the ball may feel like it is coming in slower and it is just allowing that 10th of a second for a player to be able to adapt.

"Everything we are a looking at, the consistency, I think we are in a good place."

The net is being put up on court three ahead of play beginning between Sonay Kartal and Viktoriya Tomova.

Everybody stay calm.

Defending champion Carlos Alcaraz has been out on the practice courts this morning.

He was a touch out-of-sorts during the round one win against Fabio Fognini, requiring five sets to move past the Italian.

Ollie Tarvet will be hoping for a repeat - and then some - if he's to beat the five-time Grand Slam winner.

Sonay Kartal is a firm favourite in the locker room and wherever she is. She's just a great person and an incredible athlete. She tried to tell me that she worked on her athleticism during lockdown and it just shows her personality. She took that time when everything else was shut down and she made improvements to herself.

Today is going to be a decent match for her, she plays Viktoriya Tomova who got the retirement from Ons Jabeur so she steps into that seeded draw now.

When we do get going, it'll be Sonay Kartal up first on court three.

The Brit's enjoyed a remarkable rise through the rankings in the past 18 months.

Kartal caused an upset in round one, beating former French Open champion Jelena Ostapenko 7-5 2-6 6-2.

She's up against Bulgaria's Viktoriya Tomova today - can she reach the third round for a second time?

Carlos Alcaraz arrived at court seven to practice this morning but the net hadn't been set up yet.

But all's well that ends well - following a court inspection and discussion with Alcaraz's team, the nets are going up and the Spaniard can have his knock.

Play's been pushed back by a further 15 minutes on the outer courts.

The picture looks a lot clearer than it was an hour ago and the worst of the rain has passed.

We've waited this long, haven't we? Not long now.

Marketa Vondrousova has found her form at the right time, she won Berlin last week and on the way to that title, she took out Aryna Sabalenka, Ons Jabeur, Diana Shnaider and Madison Keys. She hardly had an easy draw! But she is a great grass-court player.

She has grown up on indoor hard courts and you can transfer so many of those attributes on to a grass court - so things like the ball staying low, it skids through a little bit more.

Today will be a battle of movement and looking to control the baseline. It wouldn't surprise me if Emma Raducanu wants to play through the central channel a bit more to take the angle away from Vondrousova, the more angle you give her, the more she can open you up.

It's not going to be an easy match of course, she is the 2023 Wimbledon champion.

She was keen to play down her chances on the eve of the Championships, but Emma Raducanu looked in good form as she beat compatriot Mimi Xu in the first round.

But Marketa Vondrousova - today's opponent - is a step up in class.

We know the success that Katie Boulter has had over the years and it feels like it is building, two of her three titles here on the grass.

She just feels like she is ready for a big run here. She is starting to be more and more comfortable, feeling like she belongs at the top of the game and on the grass it is such a short season. If you feel comfortable on this surface, you can just lap up the points.

Former British number one Katie Boulter impressed in the first round as she beat Spain's Paula Badosa in three.

It was the sixth successive time Boulter had reached the second round at Wimbledon - but this was all the more impressive given it was against former world number two Badosa.

Her reward? A tie against Argentina's Solana Sierra.

Seven British players will be aiming to make it through to the last 32 once play gets under way.

Ollie Tarvet will be aiming to do what nobody has done since 2022 - beat Carlos Alcaraz at Wimbledon - while Emma Raducanu faces former champion Marketa Vondrousova.

Katie Boulter's meeting with Solana Sierra follows Cameron Norrie's match against Frances Tiafoe.

Elsewhere, Billy Harris, Arthur Fery and Sonay Kartal are the other British players in second-round action.
