Boca Juniors took the lead in a first period that ended 1-0, and that proved enough to settle the contest. From there, the shape of the game was clear: protect the advantage, deny CD O'Higgins a route back, and make sure the result stayed intact through the final whistle. With the second half finishing 0-0, the scoreboard never moved again.
That split tells the story cleanly for anyone scanning the score, stats, highlights and summary. Boca found the key moment before the interval and managed the match from in front, while O'Higgins stayed alive after the break without finding the goal that would have changed the night. In summary, this was not a high-scoring Sudamericana tie, but it was an efficient one for the home side, who did enough early and then closed it out with the minimum margin.
