As it is, the 33-year-old Strycova was the oldest first-time Grand Slam semifinalist in the professional era.
It was a far cry from the stuttering performance Williams showed in her three-set quarter-final against compatriot Alison Riske on Tuesday, who was able to drag Serena into the type of dogfight Strycova - Johanna Konta's conqueror in the quarters - was unable to muster. Williams has dominated Strycova's second serve, but nonetheless Strycova wins the game and shouts, "Come on!"
There were no intimidating roars of "c'mon", few fist pumps and the volume was turned down on the grunting that often accompanies her matches as Serena Williams marched into her 11th Wimbledon singles final on Thursday.
The 11th-seeded American, who lost in last year's final, will face Simona Halep in Saturday's championship match.
Williams won her 23rd Grand Slam title in Australia two and a half years ago, and since has married and become a mother.
Why wouldn't she? She owns a 9-1 career record against Halep, including a victory in the Australian Open's fourth round in January. Williams tweeted in April that she was "in tears" while watching Woods win the Masters.
Mouratoglou said that despite Williams claiming she was not thinking too much about the record, it was something they would be focussing on before the final.
And should Halep triumph, her mother may well get the chance to sit in the Royal Box next year - considering the All England Club invites the parents of title holders to see their opening match from a seat that money can not buy.
The latter descended into chaos after Williams was penalized a game for a heated argument with the chair umpire.
On Saturday, she will take on No. 7-seeded Simona Halep of Romania, a 6-1, 6-3 victor over No. 8 Elina Svitolina of Ukraine under a cloudy sky at Centre Court.
Svitolina even earned three break chances in that opening game, but Halep eventually held there on the 16th point.
Her return to form in the semi-finals against Strycova was astonishing.
For anyone, really, when Williams is at her best.
Five of the first 11 points lasted at least 10 strokes; two went 23. She also reached the Australian Open final in 2018, but her previous best at the All England Club had been a spot in the semifinals in 2014.
The former No. 1 never had that kind of success at Wimbledon until now.
However, she said she was a different player now and had taken to grass. Halep has lost nine of her last 12 final appearances overall. Then she pulled out of matches or missed tournaments entirely because of an illness or a bad left knee.
Now comes a tougher task: beating Williams. We will see what is going to happen. "I'm really excited - and also nervous - because of this (first Wimbledon final)". "Now that I am past older, I feel a little bit less pressure".
"I have more experience, I don't give up anymore", she said.
