Stop and let that breathe for a moment.
Ranked 183 in the world before the Championships began, her performances have rendered the debate and controversy prior to the tournament about whether she should be seeded - she was eventually granted a discretionary seeding of 25 - absurd. Yes, Wimbledon is a Slam she has won seven times and one where she hasn't dropped a match since 2014.
Serena Williams defeated Julia Goerges in straight sets to reach her 10th Wimbledon final and 30th Grand Slam final overall. But there is no statistic fantastic enough to convey the implausibility of the outcome - a 6-2, 6-4 win over Goerges that at once felt predetermined, yet unthinkable just a short time ago. "I'm so in a zone in terms of just wanting to keep playing", she said. "But when she plays against players when she has time, I think she's doing winners and she's going for the shots".
She would be only the second mother to win the title, only ten months after she gave birth to her daughter, Olympia. "It's absolutely incredible that she was able to recover so quickly after surgery". That changed last week. She had 14 winners and 10 unforced errors, while Kerber had three winners and - this was key - zero unforced errors.
But Serena had already made her mark on the tournament this year before she ever stepped foot on Centre Court. "Maybe one or two rounds but I got news for ya, the rest of the field is more anxious about her being about not seeded than she is".
Williams, who missed Wimbledon past year due to her pregnancy, won the grass-court Grand Slam on her previous two visits in 2015 and 2016.
"It's been a insane 10 months", Williams said. "We had so many great matches in the last years".
Serena Williams admits she's been surprised by her march to the Wimbledon final after only playing four tournaments since returning to the court. Harry's not a tennis guy but they did come to his polo'. Six months later, Williams returned the favor, beating Kerber at Wimbledon to earn her 22nd major.
"It's mentally very, very hard", Williams said. "I didn't know I would have such traumatic thoughts".
That's a revealing confession from a player who has appeared as mentally unflappable as any other woman in this tournament. I know that she is always pushing you to the limits to play your best tennis.
"Right now I'm sitting here at a semi-final of Wimbledon where a lot of people are dreaming of".
With Grand Slam win No. 24, she will equal Margaret Court as the all-time Slams leader and ditch the Open era asterisk.
Serena Williams will face Angelique Kerber on Saturday hoping to win an eighth Wimbledon singles title.
The victory over Goerges extended Williams' winning streak at Wimbledon to 20 matches, dating to the start of the 2015 edition.
Kerber, who also won the Australian Open in 2016, is bidding to become the first German woman to win Wimbledon since Graf in 1996. "So do I", Williams said.
"I was just trying to move good and take my chances". But this is different. "I have to be ready for the match of my life".
Last September, Serena Williams was struggling to walk to the mailbox. "I nearly didn't make it a few years ago", she said.
