What happened: The 2026 World Series rosters were assembled primarily through trades and scouting-driven development. Both pennant winners supplemented homegrown cores with targeted acquisitions rather than leading the league in spending.

Why it matters: The matchup offers a test case for roster-building efficiency while payroll disparity dominates October conversation. It places front-office evaluation and player development on equal footing with on-field execution for the title.

What to watch: The Fall Classic will show which depth model holds up across a seven-game series.
