Rio De Janeiro, April 16 : Argentine winger Jose Lopez struck a second-half winner as defending champions Palmeiras began their Brazilian Serie A campaign with a 2-1 home victory over Cuiaba. Sixteen-year-old forward Endrick Felipe put the hosts ahead with a fifth-minute volley before Raniele Melo headed home an equalizer on the stroke of halftime, reports Xinhua. The visitors were reduced to 10 men just before the hour mark when Filipe Augusto picked up his second yellow card for a rash challenge on Gabriel Menino.
