Boca go top as rivals slip up

Boca, who began the weekend one point behind San Lorenzo and Tigre, took full advantage after the two teams lost 3-1 to Lanus and Estudiantes respectively.

Lucas Viatri put Boca ahead in the 36th minute when he tapped in an easy chance after Alvaro Gonzalez pulled the ball back from the byline.

Raul Saavedra equalised for promoted Tucuman with a long-range shot in the 59th minute but Boca regained the lead three minutes later when Luciano Figueroa volleyed in from Juan Roman Riquelme's free kick.

Boca had Jesus Datolo sent off for a second bookable offence in the 89th minute and San Martin's Facundo Perez followed in stoppage-time when he picked up a second yellow card for diving.
