Argentina have shipped 3 unanswered goals to Uruguay in Buenos Aires.
Eight minutes before half-time, Lionel Messi floated a pass into the area, which was missed by both the advancing striker and the visiting goalkeeper, as it sneaked into the net.
Six minutes later, Lautaro Martinez swung and missed his chance on the edge of the box, but the loose-ball fell into the path of Rodrigo De Paul, who made no mistake in finding the net.
Martinez then made up for the miss, when he converted a low cross from De Paul 17 minutes into the 2nd half.
Argentina are now 2nd in their group, 6 points adrift of leaders Brazil.
