The west Algarveans looked the better team during the first half in Braga but fell behind to two cleverly taken chances from their vastly more experienced opponents.
A goal not long into the second period raised the visitor’s hopes but another successful Braga counter attack produced the final 3-1 score line.
On Sunday afternoon, Portimão will be hoping to put their first points on the board when Naval travel south to a meeting in the Stadium of the Algarve. S.B.
