Tennis legend Serena Williams announced on Tuesday that she intends to retire after the US Open.

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.
