San Lorenzo will bemoan two controversial late goals in their dramatic 4-3 defeat to Tigre but with one of the worst defensive record in the top flight there is a wider reason for Los Cuervos now being six points off league leaders Boca Juniors.
After a goalless first half was extended by a floodlight failure, those watching in a wet Victoria could have wondered why they bothered coming out. However, an exhilarating second half, full of golazos and talking points eventually saw the home side snatch the win in stoppage time.
Agustín Cardozo put Tigre ahead with a smart finish from the edge of the box but it was swifty cancelled out by a measured lob from Nicolás Blandi and an even more delicate effort by Bautista Merlini.
Alexis Castro slotted Tigre level in the 74th minute before Merlini headed his second of the game and looked to have won it for the visitors.
Two minutes remained when Germán Delfino harshly penalised Paulo Díaz for a handball, allowing Carlos Luna to slot home an equaliser and in injury time, Argentina under-20 international Ramón Mierez headed the winner from a suspiciously offside position.
Later in Mendoza, River Plate continued to show their resurgence in 2017 with a well deserved 2-1 win over Godoy Cruz, climbing to fifth in the table.
A wonderfully deft finish by Lucas Alario gave River the lead and although Augusto Batalla spilled a powerful Javier Correa effort into the net to gift Godoy Cruz an equaliser, the visitors remained on top.
Gonzalo Martínez was maintaining his fine form from recent weeks and tormenting the hosts but as it looked as though El Tomba may frustrate River, Rodrigo Mora popped up to head in a late winner.
It isn’t yet Gallardo’s Libertadores winning River but there is a greater balance to the side in 2017 and with Martínez in his current form, Los Millonarios are a threat for any Primera side.
In Parque Patricios, Huracán’s lack of firepower once again proved costly as Patronato were able to hold El Globo to a goalless draw. The point does little to help Juan Manuel Azconzábal’s side in their efforts to confirm Primera survival.
