Porto continue to dominate
Porto retained their 11-point lead at the top of the Liga Sagres table with a routine 2-0 win at Braga.
Argentina defender Nicolas Otamendi was the hero for the visitors as he grabbed both goals.
Second-placed Benfica ensured they didn't lose any ground on their rivals as they eased to a 3-0 win over Guimaraes. Sidnei opened the scoring before the break with Pablo Aimar and Jorge Carlos Martins completing the win.
Rio Ave climbed out of the relegation zone as strikes from Joao Tomas and Pinto Yazalde sealed a 2-0 win over bottom side Portimonense.
Substitute Mario Rondon grabbed a winner in injury time to help Pacos Ferreira beat Maritimo 1-0 while Naval were 3-1 winners against ten-man Academica.
Academica had Habib Sow sent off for a professional foul and Kevin Gomis tucked away the resulting spot kick.
Michel Simplicio doubled Naval's lead but they then had Gomis sent off early in the second half. However, Amaral grabbed the third to seal the win.
