During the "battles" round, two contestants from each team go head-to-head in a duet of the same song to determine elimination. Davis and singer Tarralyn Ramsey had to "battle" it out with Beyonce's "Single Ladies (Put a Ring on It)." Christina Aguilera, who had chosen both singers to be on her team during the initial audition rounds, had to make the decision whether to advance Davis or Ramsey; the Grammy winner chose Davis.
The next episode of "The Voice" will air May 17 at 10 PM ET on NBC. Carson Daly hosts.
