Ticket prices for US Open women's final drop by 83 percent after Serena's Grand Slam bid ends

Talk about a market crash.

Ticket prices in the secondary market for the U.S. Open women's final dropped by 83 percent after Serena Williams' bid for the Grand Slam ended with her loss against Roberta Vinci in the semifinals on Friday.

With high expectations for the first Grand Slam since 1988, the USTA said the women's final sold out before the men's, days ahead of the first match of the tournament. The cheapest ticket prices on resale website Stubhub.com for the Saturday match reached $271 after Williams defeated her sister Venus in the quarterfinals on Tuesday.

Minutes after Vinci pulled off one of the biggest upsets in tennis history to set up an all-Italian final against Flavia Pennetta, tickets could be found on the same website for as little as $45.
