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.
Halep now has $33 million in career earnings.
On top of her game right from start to finish, Halep overwhelmed Williams 6-2, 6-2 in stunning fashion for her second major championship. Before taking her seat, she had some royal duties to attend to, meeting with some of the junior players from Russia, Latvia and France.
"I've got to keep trying, keep fighting and enjoying the sport", the American said.
"The finals I lost in the past helped me for sure to be different when I face this moment", Halep said.
This uncompromising attitude and refusal to go with the flow served her well when faced with Williams.
Serena Williams's march towards the Wimbledon final has seen some rocky moments. There were times in the match when Williams was more spectator than player.
However, Halep would soon get her hands on a major when she finally became a grand slam champion in Paris when she triumphed on the French Open clay against Sloane Stephens.
"Well, I had nerves".
"It was the best match I have ever played", Halep said. At times she looked overcome with the pressure and the weight of the record books.
Couldn't have been any better, really. "When I was 10, 12 years old, she said I had to play the final of Wimbledon".
"I decided before the match that I'm going to focus on myself and on the final of Grand Slam, not on her", said Halep, 27.
Williams has struggled with injuries recently and has also begun other ventures outside of tennis.
"She's got a baby, she's trying to help gender equity, particularly women of color", King said.
Mair is confident he has the Williams vs. Halep victor, plus he's going big on how many sets it lasts.
Halep tracked down everything, as is her wont.
Williams needs to pick up her play in a hurry if she wants to claim another Wimbledon title.
Romania's Simona Halep celebrates after defeating United States' Serena Williams during the women's singles final match on day twelve of the Wimbledon Tennis Championships in London, Saturday, July 13, 2019. Not only is he picking the victor, he's also betting on how many sets it goes and the exact score of the first set.
Williams had 26 unforced errors, compared to just three for Halep.
Williams, in stark contrast, came out looking a bit tight, short-arming shots and accumulating nine unforced errors before conjuring up a single victor.
"She literally played out of her mind". We are told to sit down and be quiet, which frankly is just not something I'm okay with.
Halep knew there would be a backlash and Williams raised the decibel level at the start of the second set, bent double, fists clenched and bellowing after a volleyed victor. She leaned forward and yelled, "Come on!" Halep broke to lead 3-2 in that set when Williams pushed a backhand long, and there wasn't much left from there.
She added: "I have worked a lot to change my game, to be able to win matches on grass". "It was one of my motivations before this tournament".
'I lived it with [Boris] Becker, lived it with [Goran] Ivanisevic and lived it again today, ' Tiriac had been saying before he was interrupted.
