Roberto Carlos helps Timão go top
O Timão moved two points clear of newly-promoted Ceara, after the former Brazil left-wingback's 38th-minute opener and the veteran playmaker's 52nd-minute effort against the team he helped to FIFA Club World Cup glory in 2006.
Hugo scored twice as Gremio won 2-1 against ten-man Atletico Mineiro. Joao Pedro scored for the visitors, who also had Ricardinho sent off with six minutes to go.
Rodrigues Roger scored the only goal in the last minute as Guarani beat strugglers Vasco da Gama.
