San Martín de Formosa beat Douglas Haig 4-1 at the Miguel Morales stadium in Pergamino and claimed top spot in their Federal A group. Marcelo Rubino's team settled the match emphatically by punishing each mistake from the hosts.
Douglas began with more possession, but San Martín changed the contest within minutes. Mauro Siergiejuk opened the scoring after ten minutes and Gervasio Núñez doubled the lead on 19 after a move that left the goal exposed.
The third blow arrived after 39 minutes. A shot from outside the area troubled the home goalkeeper and Gianfranco Alegre collected the loose ball to make it 3-0 before half-time. The visitors' efficiency contrasted with the Fogonero's difficulty creating danger.
Sebastián Cejas reshaped his team and Douglas pulled one back through Marcos Giménez four minutes into the second half. The response did not last: San Martín kept their structure and prevented the home momentum from developing into a comeback.
Lautaro Cerato went one-on-one and scored the fourth goal after 20 minutes. The 4-1 score reflected the difference between a practical, united Formosa side and a Douglas team punished heavily for its errors in a short Championship Group.
San Martín host Sportivo Belgrano de San Francisco next with the lead in their hands. Douglas have an immediate chance to respond on Wednesday against Defensores de Belgrano de Villa Ramallo, needing to recover both points and performance.
