- Serena's seventh Wimbledon triumph gave her an historic 22nd Grand Slam title, equalling Steffi Graf's Open era record. Her win sets the stage for a redux of the 2016 Wimbledon final in which she defeated Angelique Kerber, who will also be her 2018 opponent.
Remarkably, the 36-year-old was back in a Grand Slam final just 10 months after giving birth to her daughter Alexis Olympia.
The 36-year-old's pregnancy ended with an extremely hard delivery that left her needing several operations to prevent life-threatening blood clots.
"It's insane. I don't even know how to feel. I lost count after, like, four surgeries because I was in so many", Williams said after beating Julia Goerges to reach her 10th Wimbledon final.
Williams' pregnancy was not without complications, as she told the BBC this week: "It's no secret I had a super tough delivery". This is not inevitable for me, I had a really tough delivery and multiple surgeries and nearly didn't make it to be honest. "It's such a pleasure and a joy [to be in the final] because less than a year ago, I was going through so much".
"This is not inevitable for me". "Now she's supporting me in a different role, but our friendship is still exactly the same".
Gorges, who had spent more than 10 hours on court before this match, the longest of any of the semi-finalists by around two and a half hours, was put out of her misery on Centre Court in just 70 minutes. The fact is, grass forces Kerber to do exactly what she needs to do in order to play her best tennis: be aggressive.
Regardless of her world rank of 183, Williams was given the 25th seed at Wimbledon as the All England Club overruled the WTA's positioning of Williams in world tennis.
If Ms Williams takes the title on Sunday, she will write herself into the Wimbledon history books. She returned the following year and won a world title before adding Olympic silver to her collection in Rio and then retiring, and has since added daughter Olivia to her family.
- With five Grand Slams in her trophy cabinet, Serena was well established as a global star, but the Williams' sisters popularity with fans was still hit and miss after a less than warm reception at the French Open. "That shows that she has a lot of respect for me, really going for her shots".
When a panicked Goerges error wrapped up the first set, Serena's dominance was so total that the American, whose emotions are usually on full display, barely acknowledged the moment.
It worked. The 11th-seeded Kerber reached her second final at the All England Club by avoiding too many mistakes and using a seven-game run to seize control for a 6-3, 6-3 victory over the 12th-seeded Ostapenko on Thursday.
Despite making 18 first-set winners compared to only six from Kerber, the 21-year-old also made 19 unforced errors, with Kerber only making two. "I think it will be just like the last final; it will be really good".
"I don't want to limit myself", Williams said.
"It's such a great feeling to be back in the final".
It's been two years and a lifetime since Williams, 36, and Kerber, 30, met on Centre Court.
