BUENOS AIRES, March 7 (Xinhua) -- A first-half goal from former Brazil international midfielder Rodriguinho gave Cruzeiro a 1-0 victory at Huracan in their opening Copa Libertadores group match here on Thursday.

The 30-year-old latched onto a lofted Robinho Signorini pass before firing a low shot past Paraguayan goalkeeper Antony Silva at Huracan's El Palacio stadium in Argentine capital Buenos Aires.

The Brazilian side defended resolutely thereafter to move to the top of Group B in South America's premier club competition.

Meanwhile, Ecuador's LDU Quito scored either side of halftime to secure a 2-0 home victory over Penarol of Uruguay.

Nicolas Freire gave the hosts the lead in the 25th minute at their Rodrigo Paz Delgado stadium and Rodrigo Aguirre added another goal eight minutes from time. Enditem
