Club Atlético Unión and San Lorenzo played out a tense 0-0 draw at the Estadio 15 de Abril on February 14, 2026, in a Liga Profesional fixture that offered more defensive solidity than attacking flair. The result did little to aid either side's ambitions in the early stages of the season, with both teams leaving the pitch frustrated by a lack of cutting edge. The best chance of the match fell to San Lorenzo in the first half, but their forward's close-range effort was brilliantly saved by Unión's goalkeeper. Unión grew into the game and had a strong penalty appeal waved away in the second period, but neither side could find a breakthrough. The shared points reflected a match of few clear opportunities, with both defenses ultimately coming out on top in a hard-fought midfield battle.
