Argentina scored its first three goals in the first minutes of play, with Ian Subiabre (sixth minute), Echeverri (eight), and an own goal by Igor Serrote (11th).

“We did an amazing job, we were ready for this,” Echeverri said. “We are always motivated to play against Brazil. We will not relax, we need to keep improving.”

South America’s U-20 championship will give the top four teams a place in the age category’s World Cup in September in Chile. Brazil has a record 12 titles in the South American U-20 championship.

The first three teams in each of the two groups will advance to a six-team round-robin tournament. The top four will secure their berths in Chile.
