BUENOS AIRES, Sept. 15 (Xinhua) -- Defensa y Justicia extended Boca Juniors' poor start to the Argentine Primera Division season with a 1-0 home defeat of their Buenos Aires rivals on Friday.

Nicolas Fernandez put the hosts ahead against the run of play when he slotted a shot past goalkeeper Enrique Bologna following Gaston Togni's through ball.

Boca Juniors completed more than twice as many passes as their opponents but lacked a cutting edge in the final third as they slumped to their third loss in four matches.

The result leaves Defensa y Justicia fourth in the 14-team Group B while Boca are 12th.

In other Argentine Primera Division fixtures on Friday, Platense won 2-1 at home to Lanus, Independiente overcame Huracan 1-0 at home and Estudiantes held Tigre to a goalless draw away from home.
