What happened: Matt Edwards entered in the 80th minute for Paulo Diaz, who made his MLS debut in August. Edwards took over on the right side of the defense following a 67th-minute goal that trimmed the deficit to a single tally.

Why it matters: The late tactical switch injects fresh legs along the back line for the final stretch of postseason play while chasing an equalizer.

What to watch: Ten minutes of regulation plus stoppage time remain to find a tying goal.
