'The Voice' Rounds Out the Top 20 of Season 3

When "The Voice" returned with its second part of Knockout Rounds, Christina Aguilera and Blake Shelton had to chop down half of their teams. The only female coach set up a battle of two powerful singers by pitting Devyn DeLoera against Laura Vivas. "I want to see who can deliver a powerful performance under pressure," she said of the pairing.

Devyn belted out "I Have Nothing" by Whitney Houston, while Laura chose Marc Anthony's "I Need to Know" and sang half of the song in Spanish. Xtina landed her choice on Devyn, hinting that she made the decision because Devyn had a better connection to her.

Next, there was a battle of two other powerful singers, Adriana Louise and Celica Westbrook. Adrianna went with "Already Gone" by Kelly Clarkson, while Celica delivered a rendition of Justin Bieber's "Never Say Never" which matched her age. Xtina kept Adriana in her team, telling Celica, "Don't hate me!"

Next, two contestants with different style met in a showdown. Alessandra Guercio tried to show off her big vocal through Rihanna's "Take a Bow" which didn't really work, while Dez Duron sang Lionel Richie's "Stuck on You". Xtina sent Dez through to the next round although she praised Alessandra's raspy tone.

Chevonne and De'Borah fought against each other in a "fun" matchup, with the former going fun and silly in her performance of "Dancing with Myself" by Generation X. The latter, meanwhile, picked "You Found Me" by The Fray. Xtina sent De'Borah advancing.

In the last battle from Team Xtina, Aquile sang "Grenade" by Bruno Mars and Sylvia Yacoub chose to perform her coach's hit "Fighter". She gave her vote to Sylvia, gushing on her team of five, "I've got five amazing people on my team and they're going to rock."

From Team Blake, there was a battle of two country singers, Gracia Harrison and Liz Davis. Gracia put a country twist to "I Don't Wanna Miss a Thing" by Aerosmith, and Liz went with Miranda Lambert's "Gunpowder and Lead". Blake said he's "confused" by Gracia's song choice, and chose to keep Liz in his team.

Next, Rudy Parris and Terry McDermott met in a battle of rockers. The former delivered his own version of Chris Brown's "Forever", while the latter performed "Maybe I'm Amazed" by Paul McCartney. It was an easy choice for Blake as the other coaches rooted for Terry and he agreed with them.

Blake paired Colin McLoughlin and Michaela Paige because "they both have great command of their tone and pitch." Colin sang "Breakeven" by The Script, as Michaela did "Love is a Battlefield" by Pat Benatar. "It comes down to what I'm into the most," Blake explained before revealing Michaela as the winner.

In another battle, Julio Cesar Castillo went with Bieber's "Somebody to Love" and MarissaAnn chose "Lady Marmalade". Blake sang praises for both singers, but sent MarissaAnn home eventually and kept Julio in his team.

For the last battle in the Knockout Rounds, Cassadee Pope was pitted against Suzanna Choffel. Cassadee went with Maroon 5's "Payphone" and she impressed Adam Levine. Suzanna, meanwhile, delivered a rendition of Bob Marley's "Could You Be Loved". Blake chose to send Cassadee advancing, gushing, "I really think we have the most diverse team. I really think I could win this thing again, I do."

When the show returns next week, it will begin The Playoffs where viewers can vote for their favorites.
