Mauro Zarate scored an impressive solo goal for Velez, as they continued Boca's poor start to the Torneo Final campaign, with the Buenos Aires giants slumping to their third loss after five rounds.
Colon trumped Rosario Central 1-0 on Saturday to stay top of the table but Velez remain in touch, two points behind, alongside Estudiantes, who drew 0-0 with Newell's Old Boys on Sunday.
At Velez's Estadio Jose Amalfitani, Zarate scored the only goal of the game in the 29th minute when he controlled Fabian Cubero's long ball forward, held off two visiting defenders and slammed his shot beyond Agustin Orion's outstretched right hand and into the corner of the net.
The goal was Zarate's fifth in the past four Primera Division fixtures and took him to the top of the goalscoring charts, while his team rose to 10 points with their goal difference of plus five putting them above of Estudiantes (10 points, plus two).
