The match was still finely balanced at halftime, with both sides locked together at 1-1 after the opening period. From there, Deportes Limache seized control. A 3-0 second-half split told the story of the night, as the home side pulled away and left San Marcos de Arica with too much ground to recover.
That swing after the interval settled the score emphatically and gave the home crowd at Estadio Gustavo Ocaranza a comfortable finish after a more competitive start. In simple stats terms, the game broke cleanly into two parts: level through 45 minutes, one-way traffic after the restart.
For Limache, the result continued a strong head-to-head run against Arica. The home side had already won the previous Copa Chile meeting between the clubs 3-1 away, and this latest margin underlined that edge again. For Arica, the night followed the same pattern as the previous cup clash - competitive for spells, but unable to contain Limache over the full 90 minutes.
It was a straightforward summary by full time: a 1-1 first half, then a decisive Limache takeover.
