What happened: Gonzalo Tapia replaced Martínez and Chambost came on for Gomes as Columbus opened the second half. The move reset two spots with a place in the final still at stake.

Why it matters: A double change at the break points to an immediate tactical adjustment rather than a wait-and-see approach. Fresh legs carry added weight in a knockout setting where one swing can decide who advances.

What to watch: Watch whether Tapia takes on a larger role from here and whether the reshaped group changes Columbus' tempo after halftime.
