San Lorenzo moved to the top of Argentina's Clausura with a single goal victory over struggling Boca Juniors.

Aureliano Torres got the only goal after 66 minutes to move San Lorenzo to the top of the pile, ahead of Olimpo and Banfield on goal difference.

Argentinos Juniors ended a run of four draws with victory over Arsenal Sarandi, with 1-0 again the scoreline.

Salcedo Gonzalez scored 13 minutes from time to move Argentinos into the top half - and deny Arsenal the win they needed to take joint leadership.

Saturday's other game saw mid-table rivals Lanus and Gimnasia La Plata draw a blank with a goalless draw.
