The 19-year-old Rodrigo, who performed her signature hit while seated on the hood of a white Mercedes on the Grammys stage, triumphed over Saweetie, Glass Animals and others to win the new artist accolade at the televised ceremony in Las Vegas.

Rodrigo was nominated for the top four Grammys: best new artist and song, record and album of the year. But she lost out on at least one of those categories when song of the year went to Silk Sonic's 1970s-inspired R&B song "Leave the Door Open." The group, the duo of Bruno Mars and Anderson.Paak, performed the hit on stage to open awards show and returned minutes later to accept their trophy.

Jon Batiste, a multi-genre artist who went into the day with a leading 11 nominations, landed four early awards. They included best music video for "Freedom," a vibrantly colored tribute to New Orleans, and best American roots performance for "Cry."

Winners were chosen by some 11,000 voting members of the Recording Academy.
