BUENOS AIRES, Argentina (AP) – Boca Juniors moved into sole possession of first place in Argentina's Apertura tournament by beating San Martin 1-0 on Sunday thanks to a 75th-minute goal from Walter Erviti.
Boca improved to 14 points from six games, one ahead of Rafaela.
Lanus could move even on points with Boca with a victory in its Monday game against Argentinos Juniors.
In other results on Sunday, Arsenal defeated Banfield 1-0, Belgrano beat Independiente, 2-0, and Union defeated Velez Sarsfield 1-0.
Boca is trying to win its first title since taking the Apertura championship in 2008; an unusually long spell without a trophy for one of Argentina's most popular clubs.

Belgrano defeated Independiente 2-0, with both goals from Cesar Pereyra.
Paulo Rosales' 87th-minute goal provided the winner for Union over Velez.
In Friday and Saturday matches it was : Rafaela 0, Newell's 0; Colon 3, San Lorenzo 1; Godoy Cruz 6, All Boys 1; Tigre 3, Estudiantes 1; Racing 1, Olimpo 0.
