There will be no calendar Grand Slam for Serena Williams this year.

The fiery #1 Women’s Tennis player in the world won the first three major tournaments in 2015–Australian Open, French Open and Wimbledon–and was expected to blow through the U.S. Open by many, especially after outlasting her sister, Venus, in the quarterfinals.

Well, Roberta Vinci had other plans.

The #43 player in the world, Vinci, of Italy, just pulled off an inspiring victory at Flushing Meadows, beating Serena in 3 sets to move on to the U.S. Open Final, willing the crowd to cheer for her as well as Serena as she left it all on the court in the biggest victory of her career.  Following the loss, Tickets to the U.S. Open Women’s Final dropped %126 per ticket site Rukkus.com

Head up, Serena. It’s been a great year. Plus, look what you’re headed home to.
