Serena Williams has let a few ball tosses fall to the floor unstruck as she practices her serve in the warm-up.

The wind is ruffling her skirt hem. Is it ruffling her composure as well? We are about to find out.

Williams to serve.

James Keothavong, 34, has previously umpired the men’s singles final in 2014, the men’s doubles Final in 2010, the women's doubles final in 2009 and the mixed doubles final in 2006.

It is pretty blustery here and that will be an issue for the players to play to the level they want to. 

For me that benefits Kerber because Serena will not be able to go for the shots she wants to.

Serena Williams removes the regulation-white jumbo earphones that she wore out onto court, takes a leisurely sip of isotonic and eventually gets off her stool to join the umpire, coin-tosser Uma and her opponent at the net.

If she moves as slowly on court as she has in getting onto court then Kerber has a chance.

The wind is swirling around the hallowed stands of Centre Court. That could monkey with both players' ball toss.

Kerber has got to get off to a good start.

Serena has a tendency to get off to slow starts.

The nerves will be different for Kerber walking out at Wimbledon.

I think Serena will be thinking about the three Grand Slam defeats but she has been so open with it.

She has something so real to play for, to be the greatest player of all time, that adds pressure but motivates her to practice more and more.

The two remaining singles ladies walk out onto the Centre Court grass.

They're both adhering to the strict dress-code in all-white, and carrying huge blooming bunches of flowers. 

Helping out with the coin toss today is young Uma Baker-Bahl.

The 11-year-old from East London is representing charity Barnardos. Uma helps care for her mum and auntie. What a moment for her - she's a big Serena fan, apparently.

Alfie Hewett: "The atmosphere was unbelievable. To see so many family and friends here helped us pick up our intensity. Just a massive thank you to all of you.

Gordon Reid: "It was horrible in that tight third set. It has been a dream of mine to play singles here since I was a kid and tomorrow I get that chance. I will put it all in just like I did today."

After and exhausting final set that lasted well over an hour, here's the moment that Gordon Reid and Alfie Hewett finally got over the line to win the men's wheelchair doubles title...

Andy Acton: @alfiehewett6 You've just made it on to my heroes list. A true sporting giant and inspiring stuff.

Lois Savage: What a cracking Wheelchair tennis match! Well done @alfiehewett6 @GordonReid91

They've done it!

Houdet is trying to ensure Peifer doesn't plateau. They are a well-versed pair and Houdet knows how to get the best out of his partner. That's why he's remonstrating with him. That's how they do things.

Houdet has just rather forcefully hit Peifer's arm and continues to shout instructions at his partner. 

Some light reading for Serena Williams, Angelique Kerber, Andy Murray and Milos Raonic this weekend.

How do you play the biggest point of your life?   

Wimbledon's official data supplier IBM has crunched the numbers on the past 12 years of championship points in Wimbledon men's and women's finals to tell us more.

The full story is here.

There is no separating the men's wheelchair doubles pairs in the deciding set.

Britain's Alfie Hewett and Gordon Reid are into a shoot-out against the French duo of Stephane Houdet and Nicolas Peifer.

As you may well know, Sunday's men's final will be between Canadian sixth seed Milos Raonic and Britain's very own world number two Andy Murray.

It will be a first major final for Raonic, while Murray is looking for his second title here at Wimbledon.

In his BBC Sport column, Murray discusses his game plan for the final, his coaching relationship with Ivan Lendl and being a new father.

Knowing Serena has lost her last two finals will give her extra motivation.

She is not going to let it slip through her fingers again. The grass is tailor-made for her game.

Champagne on ice on court 17.

Britain's Alfie Hewett and Gordon Reid have twice served for the wheelchair doubles title. Twice Stephane Houdet and Nicolas Peifer have knocked them back.

It is a real arm wrestle out there. 

On we go.
