BUENOS AIRES — Crowd violence marred the biggest match of the Argentine league season at La Bombonera Sunday after River Plate scored the fastest goal in a “superclasico” before being held 1-1 by Boca Juniors. Midfielder Manuel Lanzini rose between Boca's central defenders to head River into the lead after 45 seconds from Carlos Sanchez's cross. Uruguayan Santiago Silva equalized six minutes before halftime when he steered the ball right-footed inside the far post from Walter Eriviti's square ball on the right. However, the match was held up for 10 minutes in the second half when River coach Ramon Diaz was sent to the stands for ‘insulting' the ref. — Reuters
