What happened: San Diego included Ethan Salas among three catchers on its Wild Card roster for Chicago. Chicago and San Diego sit scoreless with the game yet to start.

Why it matters: Carrying a third catcher trims bench flexibility for a short series. Turning to a 20-year-old behind the plate in October signals present-tense trust, not development time.

What to watch: Watch how San Diego distributes starts among its three catchers once the Wild Card round begins.
