Fluminense increased their advantage atop the Brazilian Campeonato standings to four points on Sunday thanks to a 3-0 win over Internacional while second-placed Corinthians went down 3-2 at Avai.
First-half goals from Filho Mariano and Washington set Fluminense on their way and Emerson's strike just before the hour mark sealed the win. Rafael Sobis was sent off three minutes from time to compound the visitors' misery.
Corinthians were undone by two goals early in the second half at Avai. Chicao put through his own net in the 47th minute and Rafael was on target five minutes later to put the home team 3-1 ahead after Davi's early goal had been cancelled out by Bruno Cesar.
Bruno Cesar notched his and his team's second goal 15 minutes from the end to reduce the deficit but the equaliser was not forthcoming. Rafael was sent off in the last minute for the hosts but there was no time for the visitors to make the most of their extra man as Avai climbed to third.
Elsewhere, Ricardo Oliveira's last-gasp leveller earned Sao Paulo a 2-2 home draw against fifth-placed Cruzeiro and Nilton's 80th-minute goal secured Vasco da Gama a 2-1 win at Gremio Prudente after Joao Vitor looked to have earned the hosts a point by cancelling out Eder Luis' opener.
Henrique was on target twice in Vitoria's 4-2 win over nine-man Santos, Edu Dracena and Marquinhos seeing red for the visitors, while William Magrao also notched twice as Gremio beat second-bottom Goias 2-0.
