Sao Paulo took over as leaders of the Brazilian Campeonato with a 2-1 win at home to Atletico Mineiro on Wednesday.
The hosts made a flying start when Lucas scored in the opening minute and, while Atletico levelled through Rever on 10 minutes, Dagoberto clinched the win on the hour. Atletico's hopes of recovering for a second time were undermined by Leonardo Silva's 79th-minute dismissal.
Sao Paulo are now a point clear at the top although they have played a game more than Corinthians and in-form Botafogo, who thrashed Ceara 4-0.
Botafogo's fourth successive win was built on German Herrera's double either side of the break. Sebastian Abreu and Cidinho added further goals as Ceara, who had Fabricio sent off just before half-time, were cast aside.
Internacional scored three times inside the opening 15 minutes as they beat bottom-placed America MG 4-2 to end their four-game winless streak. The Porto Alegre side were in control thanks to the early strikes from Rodrigo Moleda (two minutes), Leandro Damiano (eight) and Andres D'Alessandro (14). Andre Dias (24) replied for America as a six-goal half was completed by Oscar (34) and Kempes (36).
Santos recovered from a goal down to beat Avai 2-1 with two late goals. Avai went ahead through William's 33rd-minute penalty but Santos stormed ahead when Borges (70) and Felipe Anderson (76) struck in quick succession.
In late matches, struggling Atletico Paranaense showed plenty of spirit to earn a point against Palmeiras. Buss Henrique gave Palmeiras - beaten in just four of their previous 21 games - a 14th-minute lead in Curitiba.
Although Joffre Gueron levelled in the 34th minute, the home side were up against it when Cleber Santana was dismissed two minutes later. Jose De Santana restored Palmeiras' lead in the 52nd minute - but the second from bottom home side grabbed a point with Marcinho's penalty 20 minutes from time.
Midtable Atletico Goianiense and Figueirense shared two goals, with Silva Wellington giving Figueirense a 10th-minute lead, only for Santos Agenor to level four minutes later.
Finally, Fluminense had Fred and Marquinho to thank for their goals either side of half-time in a 2-1 win at Cruzeiro, who pulled a goal back through Walter Montillo.
