Buenos Aires: Striker Lucas Viatri headed two goals as Boca Juniors beat Atletico Rafaela 2-1 on Sunday to go top of the Argentine championship with a little help from their arch-rivals River Plate.

River scored a late equaliser through central defender German Pezzella for a 1-1 draw away to Colon at the ‘Elephant’s Graveyard’ in Santa Fe that denied the home side the victory that would have put them top.

Viatri took his championship tally to three with goals in each half including the 69th-minute winner at La Bombonera. In between, Sebastian Carrera had equalised for the visitors.

Boca have 12 points from four successive wins after losing their opening match of the season. They are one point ahead of title holders Arsenal, Newell’s Old Boys and Colon.
