For long stretches, the tie was moving in Deportes Copiapo's direction after the visitors went in front before the break. That first-half edge put the pressure squarely on CD Universidad Catolica, but the response arrived after half-time and completely changed the result.
The split score by period told the story better than anything else. Copiapo won the first half 1-0, then Universidad Catolica took the second half 2-0 to flip the match. In a cup game, that kind of swing is usually decisive, and it was here as the hosts closed out a 2-1 victory at Claro Arena.
This result also extended Universidad Catolica's recent upper hand in the matchup. They had already beaten Copiapo 3-0 in the other Copa Chile meeting, and their previous four recorded meetings before this one showed three wins and a draw. For anyone checking the stats, highlights and full summary, the headline was simple: Copiapo struck first, but Universidad Catolica finished stronger and took the win.
