What happened: One option pairs Jonathan Aranda with Richie Palacios and the other pairs Jake Bauers with Brice Turang. The split separates the first-base matchup from the second-base matchup entering the Fall Classic.

Why it matters: First-base production and second-base range carry outsized weight when rotations shorten and every baserunner matters. Choosing power at first or stability up the middle changes pinch-hit and defensive-replacement options late in close games.

What to watch: Starting lineups for Game 1 will show which duo opens together and which matchups follow late.
