Every week there's a lot happening on the WTA - on the court, off the court, by the numbers, even a few tweets... catch up on it all in this week's WTA Diary.
Despite stiff competition in the form of the NFL opening weekend, according to host broadcaster CBS, Serena's showdown with rival Victoria Azarenka drew in 19.3 million viewers - the highest number since 2002's all-Williams final.
Twitter's Take On Serena Vs. Vika
Here's what Serena and Vika's peers had to say on Twitter about their three-set thriller.
Serena And Bill
With the assorted luminaries from the world of film, fashion and politics in the crowd, the US Open cameramen were spoilt for choice in terms of people watching. However, it was one political heavyweight that stole the show. No, not former NYC mayor David Dinkins, but the 42nd President of the United States, Bill Clinton, who it turns out goes way back with Serena.
"I have met him several times," Serena said. "We reminisced about when I was a teenager and how he first saw me then coming to the White House and several times at the US Open. So it was interesting, because we actually have a history. That's kind of unique to have a history with a former President of the United States of America."
Busy, Busy, Busy
While the days following Serena's title triumph were spent posing for the camera in Central Park, charming breakfast show presenters and chatting with former leaders of the free world, two other champions were back with their noses to the grindstone. After a night on the town celebrating, doubles winners Andrea Hlavackova and Lucie Hradecka hopped on a flight north of the border in search of more silverware and ranking points at the Challenge Bell in Québec City.
Talking of doubles, Martina Hingis has been discussing the highs and lows of her second comeback.
While Hingis has recently returned to the fold, Thursday saw another former Top 10 player, Anna Chakvetadze, formally announced her retirement from tennis due to a chronic back injury.
