Viatri brace sends Boca back to top

Arsenal Sarandi's stay at the head of the standings proved short-lived as Lucas Viatri's brace either side of an equaliser from Sebastian Carrera gave Boca its fourth win of the season.

There was also a 2-1 win for Godoy Cruz, which moved up to sixth in the table with a home success against Independiente.

Cristian Tula (36) had given the visitor the lead, but David Ramirez equalised just before half-time and then grabbed the winner from the penalty spot in the last minute.

Tigre remains without a win this season after it was held to a 1-1 home draw by San Lorenzo, with both sides ending the game with 10 men.

Diego Castano (19) put Tigre in front, but the visitor levelled just five minutes later through Luis Aguiar. Tigre's Diego Castano was sent off in the 52nd minute but San Lorenzo's Franco Jara received his marching orders 12 minutes later.

The day's final game between Colon Santa Fe and River Plate also ended in a 1-1 draw.

Ruben Ramirez opened the scoring for Colon after 70 minutes, but German Pezzella grabbed an equaliser just a minute from time.
