Boca slips to third after defeat
Reigning champion Boca Juniors slipped from first to third position after the penultimate round of matches in Argentina's Clausura championship after a 3-0 loss to Arsenal at La Bombonera on Sunday.

In the key match of the day, Arsenal opened the scoring in the 2nd minute from a near post header by Emilio Zelaya.
Boca failed to respond and Arsenal deservedly extended its lead seven minutes before halftime, when Luciano Leguizamon got his first of the game with a tap in following a swift counterattack.
Boca brought on Pablo Mouche in the 40th to try to force the pace of the game, but Arsenal was dangerous on the counter and Leguizamon pounced on a loose defensive header from Rolando Schiavi in the 56th, drove towards goal and chipped the ball over goalkeeper Agustin Orion.
Boca's position got worse when Franco Sosa was sent off in the 85th.
The famous Boca Juniors club is aiming to win consecutive domestic titles and is also still alive in the Copa Libertadores - taking a 2-0 lead into the semifinal return leg against Universidad de Chile on Thursday. It is also in the final of the Copa Argentina.

Rafaela moved above San Lorenzo in the relegation league with its win.
