By his own admission Gonzalo Martínez’s 90th minute winner was in fact a cross but River Plate will not care in the least as it ensured them a place in the Copa Argentina last 16 and avoided a potential major upset against Estudiantes de San Luis.
Ignacio Fernández had given River a first half lead when his long range effort managed to find a way past Valentín Brasca and into the bottom corner and although Marcelo Gallardo’s side should have wrapped up the result the Primera B side never gave up.
Marcelo Mosset poked in an 88th minute equaliser and looked to be sending the tie to penalties but in the final stages, Martínez swung in a cross from the left and the ball drifted over everyone and in at the far post.
River will face either Defensores de Belgrano or Arsenal in the next round.
Earlier, in Sarandí, Godoy Cruz also left it late but Facundo Silva’s scrappy goal four minutes from time ensured El Tomba progressed at the expense of Banfield and they will face San Lorenzo in the last 16 after Diego Aguirre’s side saw off the challenge of Douglas Haig in Formosa.
Nicolás Blandi headed the Primera side in front and although Mauro Bazán’s deflected strike brought Douglas Haig level, Los Cuervos had enough to seal victory.
Two almost identical headers from Matías Caruzzo and Marcos Angeleri in the second half completed the win and set up the all Primera clash in the next round.
