America's Got Talent revealed the Top 6 ninth-season finalist acts during Wednesday night's live results show of the NBC reality competition series.

Emily West, a singer and songwriter from New York City; AcroArmy, a group of acrobatic gymnastics; Quintavious Johnson, a 12-year-old singer from Franklin, TN; and Mat Franco, a magician from RI, were revealed to have finished as the Top 4 vote-getters after Tuesday night's performance show, automatically earning them a spot in America's Got Talent's ninth-season finale.

Tuesday night's episode had featured the 12 semifinalist acts performing for home viewer votes.

During last night's results show, America's Got Talent host Nick Cannon revealed that Mara Justine, a 12-year-old singer from Galloway, NJ; Blue Journey, an innovative dance duet featuring video projection and animation; Christian Stoinev, a 22-year-old hand balancer and dog act; Mike "Mystifier" Super, a magician, entertainer and supernaturalist from Pittsburgh, PA; and David and Leeman, a magic duo from Los Angeles, CA, had received the five lowest home viewer vote totals.

The "Snapple Save" twist was also utilized again in which America could vote live to save one of the acts who had finished in fifth, sixth or seventh place based on Tuesday night's voting results.

America voted to advance The Sons of Serendip, a musical group of four friends, to the Top 6 finalists.

The Sons of Serendip beat out Emil and Dariel, a pair of cellists, as well as Miguel Dakota, a 21-year-old singer and guitarist from Monument, CO.

However, the AGT judges were given the power to save either Emil and Dariel or Miguel from elimination. They could advance only one of the two acts to the finals. Heidi Klum chose to advance Miguel, Melanie "Mel B." Brown picked Miguel, Howie Mandel opted to save Emil and Dariel, and then Howard Stern also chose to advance Emil and Dariel.

As a result, Nick checked the voting results to determine which act would advance since the judges determined a 2-2 tie. Miguel had received the higher amount of home viewer votes.
