RIO DE JANEIRO, Sept 14 (Reuters) - Corinthians cruised into the last 16 of the Copa Sudamericana with a 3-1 win over fellow Brazilians Vasco da Gama on Wednesday.
The Brazilian champions will meet the winners of the all-Argentine clash between Lanus and Velez Sarsfield in the second round of the competition, the South American equivalent of the UEFA Cup.
After drawing the first leg 1-1 away last week, Corinthians made the perfect start when Marcio Amoroso scored in the fourth minute of Wednesday's match in Sao Paulo with his first goal since his move from AC Milan.
Rafael Moura headed a second in the 27th minute and, although Diego reduced the arrears direct from a free kick five minutes later, Magrao completed the scoring three minutes before half time.
Magrao, one of four new signings brought in following the move of Argentine pair Carlos Tevez and Javier Mascherano to West Ham United, scored with a free kick which was deflected and wrong-footed goalkeeper Cassio.
Vasco had midfielder Amaral sent off in the 86th minute for stamping on Magrao.
Santos and Atletico Paranaense joined Corinthians after winning two more all-Brazilian ties.
Santos beat Cruzeiro 4-3 on penalties, helped by 18-year-old third choice goalkeeper Felipe who saved Cruzeiro's first effort from Gabriel.
Earlier, a second half goal by Wagner gave Cruzeiro a 1-0 win in Belo Horizonte to tie the aggregate score at 1-1.
Vanderlei Luxemburgo's team will meet Argentina's San Lorenzo in the next round.
Atletico Paranaense completed a 4-1 aggregate win over local rivals Parana in Curitiba by winning the second leg of their tie 1-0 at home.
Denis Marques swept home Paulo Rink's cross in the 78th minute to set up a second round tie against Argentina's River Plate.
