Blake Shelton showed some tough love and brought contestant Emma Carolina to tears on NBC's "The Voice.".

It started even before the first live performances of the evening, when host Carson Daly revealed the winner of the four-way knockout that between Team Blake Shelton's Emma Caroline, Team John Legend's Carolina Rial, Team Nick Jonas' Devan Blake Jones and Team Kelly Clarkson's Savanna Woods.

After the votes were tallied, Daly revealed America voted to save Blake Jones, who was overcome with emotion. "You can hear a thousand 'no's' but that one 'yes' can change everything," he said to Jonas, the only coach to turn for him in the Blind Auditions.

With Blake Jones' win, Jonas had an immediate leg up in the competition.

Team Legend is also composed of Zania Alaké (Ariana Grande's "Dangerous Woman") and Pia Renee (Jazmine Sullivan's "Need U Bad"), but his "superstar" Victor Solomon  was the clear standout on Team Legend, bringing all the coaches to their feet. 

"I would like to point out that this is the first four-coach standing ovation for the night," Legend said after Solomon brought the house down with a rendition of "I Wish" by  Stevie Wonder

Jonas said his "strong" team of "powerhouse voices" will make for "some nervous coaches." And he may be right.

"You really set the bar pretty high," Shelton said to Mac, "and what my team is about to do will shut the door."

Clarkson said Jordan Matthew Young is "way too cool to be on Blake’s team" following his rocking version of Fleetwood Mac's "Gold Dust Woman." Shelton said Matthew Young's performance "was literally a breathe of fresh air for this night."

Cam Anthony closed the show with a standing ovation for his powerful rendition of Hozier's "Take Me to Church." Shelton said he could be "the first superstar that we launch off this show."

"I’ve never had more people ask me about an artist on my team in 20 seasons of doing this show," Shelton said

Legend added, "Every time I hear Cam sing, it breaks my heart that Nick would use his block (on me) in such a way."
