On this cloudy, cool afternoon, with the temperature in the low 70s (low 20s Celsius), Halep began with a pair of service breaks and even delivered the match's first ace, at 106 miles per hour, which put her out front 4-0 after 11 astonishing minutes.
"I have to play the final of Wimbledon so the day came, so to my mom, thanks".
The US 11th seed did register again but Halep held her own serve to close out the opening set 6-2 in just 26 minutes.
Just as importantly, King also said she had no issue if Williams continued to live her life the way she has been, saying it was merely a wish on her behalf to see the superstar put all her energy into tennis.
For Williams, the loss was especially hard as it kept her from a record-tying 24th Grand Slam title, a record only held by Australian Margaret Court.
But she said those experiences had helped her here - on a surface that, as a player of 1.68m, she never thought she would be able to win on against "all these players that are very tall and serving with a lot of power". "She couldn't be a better friend to me". He told me, "Any time you want, you can come, have dinner, have lunch, play a little bit of tennis". I was really hoping to get this far. In part because of a bad left knee, she only had played 12 matches all season until Wimbledon. "I didn't think about the score at all".
'I don't know any other woman who can run as fast as Halep. I said that every time I would play a final of Grand Slam, I will do exactly the same thing.
Williams admitted she was beaten by the better player on Centre Court. I had the chance to meet her after the match.
In June, King said Williams was doing too much and would have to hunker down and focus on tennis if she wanted to win at Wimbledon.
This uncompromising attitude and refusal to go with the flow served her well when faced with Williams. John McEnroe, who had backed Williams before the final, said, "this wasn't even a match".
"So here I am", she said Saturday, the fortnight done, her trophy won. Last year, Williams lost the final to German Angelique Kerber before going on to lose the final of the U.S. Open to Japan's Naomi Osaka. "It was a little bit deer in the headlights for me". She was Wimbledon champion.
But just because Williams has dominated the rivalry doesn't mean she'll cruise to another Wimbledon crown Saturday.
