And as of 8 a.m., they had climbed much higher on the singles chart.

Sawyer Fredericks, the 15-year-old from Fultonville, N.Y., was sitting at number 65 with “Collide.”

Look for it to continue to rise on the charts. Sawyer had the most successful song from the blind auditions (“Man of Constant Sorrow”) and the most successful battle round performance (“Have You Ever Seen the Rain” with Noelle Bybee) on iTunes.

Sawyer sings for Team Pharrell.

Perhaps the best vocal in Monday’s opening night of the knockout round was delivered by Sarah Potenza of Team Blake.

The 34-year-old from Nashville, Tenn., sang “Wasted Love,” the first single from Season 7 runner-up Matt McAndrew.

As of 8 a.m., it was number 114 on the iTunes Top 200.

And Matt McAndrew’s version, nowhere on the chart before Monday’s episode began, had jumped to number 117.
