Blake Shelton loses two artists and gains one with a steal, as the knockout rounds begin on 'The Voice.'

Country girl Shelbie Z took on Briana Cuoco in her knockout round, singing Carrie Underwood's 'Last Name.'  It was a clear cut decision for Blake who thought Shelbie 'out sang' Briana.  With a voice like Shelbie's she doesn't need a last name.

Nic Hawk, who Blake stole from Adam Levine's team during the battle rounds, moves on to the live shows after putting his own spin on 'Genie in a Bottle.' Blake admires his unique personality along with his voice and thinks America will too.

For the first time in Voice history, coaches have one steal during the knockout rounds.  Blake used his to pick up Cole Vosbury, who sang 'Let Her Go.'  He had to fight Adam Levine to get him, but it made the steal that much sweeter.

The artist Blake Shelton has to watch out for this season is Tessanne Chin from Adam's team. She could stop Blake from winning a fourth season in a row. Tessanne's performance of Kelly Clarkson's 'Stronger' has her as a frontrunner.
