San Martín de Tucumán earned a valuable 1-0 away victory over Arsenal de Sarandí in the Primera Nacional on Sunday, April 27th at 19:00. The visitors displayed a disciplined defensive performance to shut out Arsenal and snatch all three points with a decisive goal. The match was evenly balanced for long periods, with both teams cautious in their approach. San Martín, however, proved more clinical when their chance arrived, scoring against the run of play. Arsenal, despite having more possession in their home stadium, lacked creativity in the final third and failed to seriously test the San Martín goalkeeper. This result is a significant boost for San Martín's away record and league standing, while Arsenal's home form remains a point of concern.
