BUENOS AIRES, Oct. 21 (Xinhua) -- Robert Rojas and Braian Romero scored either side of halftime as 10-man River Plate extended their lead in Argentina's Primera Division standings with a 2-0 victory away to title rivals Talleres Cordoba on Thursday.
The visitors were reduced to 10 men after just seven minutes when midfielder Felipe Pena was shown a straight red card for a rash challenge on Juan Mendez.
But the hosts failed to capitalize on their numerical advantage as River went ahead through Rojas' close-range strike just before half-time.
Romero doubled the lead 20 minutes from time with a low finish after Julian Alvarez's pass on the counterattack.
River now have 39 points from 17 matches and are seven points clear of second-placed Talleres.
In other Primera Division fixtures on Thursday, Argentinos Juniors won 3-1 at home to Colon, Aldosivi drew 0-0 at Newell's Old Boys and Independiente were held to a 1-1 home draw by Sarmiento.
