"It's insane. I don't even know how to feel, you know, because literally, I didn't expect to do this well in my fourth tournament back", Williams said. She's coming back and for me also I'm coming back from 2017. "I just feel like when I don't have anything to lose, I just can play so free, and that's kind of what I'm doing".
Williams took a 19-match Wimbledon winning streak into the day.
That's not the case.
The left-handed Kerber, a former No. 1 and two-time major champion, used a seven-game run to beat 12th-seeded Jelena Ostapenko 6-3, 6-3.
'She's trying to, yeah, playing like she played the years before where she won the big matches. Williams has won all four of their encounters.
Williams' movement is far from the best on tour but her game is so well oiled that it does not matter, her ability to control proceedings ensuring she was always perfectly placed to unleash another groundstroke.
At 181st in the world, Williams is the lowest ranked player to reach the women's final but that number will fool no one, and especially not Kerber who was runner-up to the American in the 2016 final.
"It's such a great feeling to be back in the finals", Kerber said after the match.
The other semifinal sees two-time Grand Slam champion Angelique Kerber take on 2017 French Open victor Jelena Ostapenko.
After the brisk first set, Goerges competed much more effectively in the second until she saw her serve broken once more to give Williams the advantage.
There were no drawn-out points in the early going, no lengthy baseline exchanges, essentially because Ostapenko wouldn't allow it. That came to an end fairly quickly as Kerber remained solid amid an onslaught of winners and unforced errors in the first set from the more aggressive Ostapenko.
While Meghan attended Wimbledon two years ago as a guest of Ralph Lauren, she has not yet made an appearance in the royal box this year.
However, the 14 errors meant that Kerber, at the third attempt, broke to lead 4-3.
The set looked to be following the same pattern as the first-Gorges had yet to earn a single break point in the entire match as she struggled to challenge Williams' serve-but the 29-year-old finally did so as Williams attempted to serve for the match. Against the No.25 seed, Goerges would need to raise the tempo, to move her opponent outside her comfort zone but the 23 time Slam champion confirmed to be the most complete player ever.
