That has caused the demand for tickets to the tournament to utterly skyrocket.

USTA spokesperson Chris Widmaier told the New York Post the news caused "unprecedented" ticket sales on Tuesday.

"You talk about the Serena effect, it’s like a tsunami," he said. "Since people have learned of the news, we’ve sold, as of 3 p.m. [Tuesday], 13,000 tickets to the Open, including 4,500 or thereabouts for opening night."

Widmaier said selling 13,000 tickets in one day is "a spectacular day."

Before Tuesday, tickets for the first night of the tournament - Aug. 29 - at Arthur Ashe Stadium were retailing for as low as 35 dollars. Now, the get-in price on Ticketmaster (only through verified resale, as no standard tickets are available anymore) is $81.55 - and that's just to buy a lone ticket. To get in with someone else, you have to fork over at least 123 bucks.

Serena Williams practices on Centre Court ahead of the 2022 Wimbledon Championship at the All England Lawn Tennis and Croquet Club, in London, Friday, June 24, 2022.

In fact, someone is currently bold enough to be selling two tickets in Section 317, Row X, Seats 13 and 14 for a measly $7,000 each on Ticketmaster's verified resale.

The demand is sky-high, yet Williams isn't even guaranteed to play on that date. The draw for the tournament is revealed the Thursday before the tournament, so we may be updating this article that night once again if it turns out the 23-time grand slam winner is indeed playing that night.

Serena Williams holds the championship trophy after beating Victoria Azarenka, of Belarus, in the championship match at the 2012 US Open tennis tournament in New York.

The women's final will be Sept. 10.
