BUENOS AIRES, Sept. 20 (Xinhua) -- Nicolas Castro scored a first-half brace as Newell's Old Boys shocked title contenders Lanus with a 2-1 away win in their Argentine Primera Division clash on Monday.
Castro rifled home a first-time effort from the edge of the 18-yard box after Maxi Comba's cross from the right flank.
The 20-year-old doubled the visitors' lead when he took one touch to control a Gabriel Compagnucci through ball before curling a shot into the top-right corner.
The hosts pulled a goal back after some tenacious defending from Angel Gonzalez, who dispossessed Facundo Mansilla before providing an inch-perfect cross for Jose Lopez.
The latter left goalkeeper Alan Aguerre sprawled on the turf with a swivel of the hips before sweeping a left-footed strike into the far corner.
Lanus missed a chance to stay on level terms with leaders Talleres Cordoba and are now fourth with 23 points from 12 fixtures. Newell's are 14th with 15 points form 12 outings.
