In the 2019 Copa América Final against hosts Brazil on 7 July, at the Maracanã Stadium, Guerrero scored the temporary equaliser from the penalty spot in the first half; the match eventually ended in a 3–1 victory to Brazil. Guerrero finished the tournament as the top scorer with 3 goals, alongside Brazil's Everton Soares, who won the Golden Boot Award due to having played fewer minutes than the Peruvian throughout the tournament.
