Quick Wimbledon history lesson folks, I know you're all fans.

New Zealand player Lulu Sun, who beat Emma Raducanu in the last round, is the first qualifier since Estonia's Kaia Kanepi in 2010 to reach the quarter-finals at Wimbledon.

If she wins today, she'll be the first qualifier in the semis since American Alexandra Stevenson in 1999.

No qualifier has ever won Wimbledon in the Open Era. Emma Raducanu became the first women's player to win a Slam as a qualifier in the Open era at the US Open in 2019.

Solid start from Donna Vekic to get the hold.

Lulu Sun did put a bit of pressure on at 15-30 but the Croatian came through with an ace to bring up game point.

A big second serve helps seal it with Sun's return going long.

Away we go, Donna Vekic to serve first and the first point of the match goes her way as Lulu Sun's forehand drifts wide.

Woohoo! We're finally about to see some play on day nine.

There's an excited atmosphere bubbling up on Court One - to be honest when's there not? Court One always feels like the chattier sibling compared to a slightly more reserved Centre Court.

World number 123 Lulu Sun will play in a Grand Slam quarter-final for the first time this afternoon as she faces Donna Vekic on Court One.

In fact, this is just Sun's second appearance at a Grand Slam so it was no surprise to see her emotional reaction after beating Emma Raducanu in the last round.

While Sun's mother is Chinese and her father is Croatian, she lives in Switzerland but was born in and represents New Zealand.

Her progress at Wimbledon is being followed closely at Te Anau Tennis Club, the 23-year-old's local club back in New Zealand with president Greg Sheppard and around 20 members glued to the clubhouse television to witness Sun's victory.

"It was nerve-racking and very exciting," Sheppard told AFP. "When she started crying, we had a few tears in the clubhouse too. It was quite emotional.

"We're fully pumped for her. It's unbelievable, something we have never had before. It'll be great to see Lulu when she is next home."

Warm applause from the crowd on Court One as the players come out for the first quarter-final at this year's tournament.

Lulu Sun suggested she might have a bit more support than she did when she beat Emma Raducanu. I think that's a pretty safe assumption.

Sun wins the toss and asks Donna Vekic to serve first. Now time for the warm-ups.

Having beaten Emma Raducanu is the fourth round, qualifier Lulu Sun takes on Croatia's Donna Vekic for a place in the semi-finals.

This is just Sun's second Grand Slam appearance but having saved a match point in the second round of qualifying, she has impressed in the main draw, beating world number eight Zheng Qinwen in three sets before overcoming home favourite Raducanu.

Sun is the first qualifier to reach the women's quarter-final at Wimbledon since Estonia's Kaia Kanepi in 2010 and the New Zealander is only the seventh woman to achieve the feat in the Open Era.

World number 37 Vekic is more experienced, this is her 10th Wimbledon but it's her first quarter-final and she had only reached the fourth round once before this year.

The Croatian, who beat Spain's Paula Badosa in three sets in the last rouns, has made two previous Grand Slam quarter-finals - the US Open in 2019 and the Australian Open in 2023 - but is bidding to reach her first semi-final.

I spoke to Italian former French Open winner Francesca Schiavone this morning.

She couldn't stop praising Jannik Sinner and thinks the top seed is ready "to become Rafa, Roger or Novak."

She believes Sinner could even reach Novak Djokovic's record of 24 major titles, adding he will easily win "more than 10 Grand Slams".

"Yes he can win here this year," she told me. "He has the quality to win here because he’s a great player."

Usually former pros on the circuit are quite reserved, and are unlikely to make bold predictions. Not Schiavone though! Her eyes lit up when I asked her about Sinner.

I was a little shocked by Djokovic's reaction.

We have always seen the crowds chant Holger Rune’s name, it sounds a little like boos which is well known. I think he just needed it to get himself fired up but it did not seem to be the issue he made it out to be.

Novak Djokovic accused some of the Centre Court crowd of using a Holger Rune chant as "an excuse to boo" as his hot-and-cold relationship with Wimbledon took another turn.

Hundreds of fans greeted Rune winners, and Djokovic errors, with elongated cries of 'Ruuuuuuu-ne' during the pair’s fourth-round match on Monday.

Djokovic - a convincing 6-3 6-4 6-2 winner - felt the crowd were disrespecting him.

When on-court interviewer Rishi Persad put it to the Serb that they were supporting his opponent, Djokovic said there was more to it.

"I know they were cheering for Rune but that’s an excuse to also boo," he said.

"I have been on the tour for more than 20 years. I know all the tricks."

As expected with the rain continuing to fall, the earliest possible start time on the outside courts has been pushed back again.

We're now looking at 13:30 BST before there is any chance of play. I'd wager that even that may be optimistic.

With rain having wreaked havoc with the schedule at SW19 - and it still is - the decision has been made to move the mixed doubles final back to Sunday.

It had originally been slated for Thursday but the rain has been such that some first-round mixed doubles are still yet to be completed.

Tournament director Jamie Baker has announced that the final will now take place following the men's singles final on Sunday, with the women's doubles final on Saturday evening after the men's doubles final.

“The scheduling committee has determined that it is no longer possible to play the mixed doubles final on Thursday and has therefore made the decision to revise the finals schedule," Baker said.

“This gives us the maximum flexibility to complete the Championships on time and to play all of the respective finals on Centre Court.”

Jon: Looking forward to this afternoon’s play at Wimbledon - get the roof on!

Harsh: Alcaraz and Bellingham! The young sensations of their games. On the way to achieve greatness.

Don't you just love UK summers?

The forecast isn't pretty once more at these Championships and already there is no play on the outside courts before 13:00 BST.

Thankfully we'll have guaranteed play on Centre Court and Court One but spare a thought for all those fans with ground passes, as well as the doubles and junior players on the schedule today.

The men's and women's wheelchair singles start today and, weather permitting, court three is the place to go to watch the best of the action, with two men's matches scheduled to be followed by two women's.

To start off with is an all-British tie between Ben Bartram and two-time finalist and second seed Alfie Hewett before Britain's Gordon Reid takes on Argentina's Gustavo Fernandez, the third seed.

Then it's the women's turn with Britain's Lucy Shuker against Kgothatso Montjane of South Africa, with the last match seeing reigning champion and top seed Diede de Groot, aiming for a sixth Wimbledon singles title, play Momoko Ohtani of Japan.

But we will have to wait before we get going as gentle rain has delayed play with the covers staying on court three for the time being. It's certainly not a downpour, but enough to start Tuesday with a delay, with no play on the outside courts before 13:00 BST.
