The grunts and ferocious focus were still there against Goerges, who put up more resistance in her first grand slam semi-final than the score might indicate. She won the 2009 and 2010 US Open and 2011 Australian Open titles after giving birth in 2008.
Let others shrug at this latest accomplishment, as if all it signified were merely another chance at another in a long line of trophies.
The 13th seed had never taken a set off Williams in three previous meetings and unfortunately for her, the American was once again at her dominant best on Thursday as she bludgeoned down five aces and 16 winners to finish off Goerges.
Even after all of that, even after more than a year away from the game, even in only the fourth tournament of her comeback, Williams showed she's still capable of dominance.
All England Lawn Tennis and Croquet Club, London, Britain - July 12, 2018.
Williams will face off with Kerber on Saturday; if she is victorious, she'll tie Margaret Court's all-time record for grand slam singles titles. The pair will now contest their third Grand Slam final, with each having won one so far.
Declaring themselves officially on "Kate watch", one fan even said they were hoping to see a "Cambridge-Sussex double date". "So I'm taking everything as it is and just enjoying every moment".
"This is not inevitable for me", Serena Williams said, alluding to the serious postpartum health problems she faced after giving birth. "That for me is the difference - she's a real warrior - that's to be admired more than anything else".
"A lot of people were saying, "Oh, she should be in the (Wimbledon) final". Ostapenko: Winners (30), Unforced Errors (36); Kerber: Winners (10), Unforced Errors (7). "I still have a match to win, so I'm not even there yet".
After a breakthrough 2016, during which she won the Australian Open and US Open and rose to No. 1 in the world, Kerber struggled with the weight of expectation in 2017, as she dropped out of the top 20 for the first time in five years. "I had a really tough delivery, and I had to have multiple surgeries and nearly didn't make it, to be honest", Williams said. "I couldn't even walk to my mailbox, so it's definitely not normal for me to be in a Wimbledon final", she said. Until the start of this tournament, that was the last match Williams played at Wimbledon.
She'll play Angelique Kerber for Grand Slam No. 24.
The first of the two matches on Centre Court seemed to hold more promise given the contrasting styles of the two players.
Williams' match against Goerges featured two of the best servers around, and began quite evenly, until 2-all, 30-all.
She is by far the most unsafe player the American has faced so far this fortnight and is on something of a comeback trail herself after a slump in 2017.
In the first set, the experienced Kerber broke twice while the only break point Ostapenko earned was when she was leading 3-2.
"She's carrying a message and on a platform that is so much bigger than a tournament or a sport, " said Jill Smoller, her long-time agent.
But there is a serious side to these outfits: the compression tights and sleeves are worn to prevent blood clots by improving blood flow, and she says it means she can "play without problems".
The second set followed a similar pattern, with the only brief wobble coming in the ninth game when Williams was broken.
