A Rodrigo Mora penalty put River Plate into the knockout stages of the Copa Libertadores.
River Plate booked their spot in the Copa Libertadores last 16 with a 1-1 draw at home to Emelec on Wednesday.
A second-half penalty from Rodrigo Mora secured a point for River in Group 3, after Ayrton Preciado had put visitors Emelec ahead in Buenos Aires.
The result kept River unbeaten and lifted them to 10 points, clear of Medellin (6), Emelec (4) and Melgar (3).
River had gone behind to a scrappy opener on the hour-mark as Preciado scrambled in after the hosts were unable to clear.
