With attention fixed on the Copa Libertadores, Lanús have seen their league form falter of late but enjoying a week off from international competition, El Granate claimed only a second win in nine as Vélez visited La Fortaleza.
The visitors’ arrived having secured back-to-back wins for the first time this season but were behind after 19 minutes when a former player came back to haunt them. Talented youngster Hernán Toledo only left Liniers last year but after struggling to get playing time in Italy, returned on loan to Argentina and provided a reminder of his potential after exchanging passes with Pepe Sand and slotting past Alan Aguerre.
Vélez had their chances to draw level but were punished shortly after the break when Alejandro Silva powerfully found the top corner from just inside the penalty area.
The champions climbed back up to 13th but their recent form has seen any hopes of a title defence disappear.
Earlier in an empty Estadio Mario Kempes, Belgrano slumped to yet another defeat as a mindless tug on a shirt gifted Defensa y Justicia a late penalty which Alexander Barboza made no mistake in tucking away.
