It's the Dodgers and the Nationals in the NLCS:
It's funny how a team's long-discarded players IRL turn out to be key contributors 8 years down the line for that same team in OOTP as DJ Peters, shipped off to Texas in the first year of this save (2021) and now (2022) playing in the KBO, instead stayed all this time with the Dodgers and was the star of their deciding NLDS Game 5.
