Episode 413

The thirteenth episode of Season 4, and the sixtieth episode of America's Got Talent overall, aired on August 4, 2009. It was the first of four Quarterfinals performance episodes and took place in Hollywood. 12 acts performed for 5 spots in the Semifinals.

Wild Card Eliminated
After a serious injury, the Russian Bar Trio was forced to withdraw from the Quarterfinals. To fill the vacancy, the judges picked eight acts as Wild Card acts eligible for the Wild Card spot. Voting was opened to America. Seven acts did not receive enough votes to be sent to win that spot, eliminating them from the competition again.
