Sao Paulo and Racing Club made it through to the Copa Libertadores group stage courtesy of 1-0 home victories.
A 1-0 home win against Mexican side Puebla saw Argentina's Racing Club advance to the group stage of the Copa Libertadores on Wednesday.
Gustavo Bou's 75th-minute strike was all that separated the teams Wednesday, after last week's 2-2 draw in the first leg.
Racing will play in Group 3 of the Libertadores, along with Boca Juniors, Bolivar and Deportivo Cali.
Sao Paulo also went through thanks to a 1-0 home victory over Cesar Vallejo.
A 1-1 away draw against the Peruvian club in the first leg meant a win or a scoreless draw was enough for Sao Paulo to get past the qualifying round.
