A quarter century of baseball, at a glance.

What each cell shows. A team's regular-season winning percentage, ranked against all 30 clubs that year. This is a league-wide ranking built for this page, not the official division standings or postseason seeding. Ties go to the team with more wins, then alphabetically.

How seasons are weighted. The Win % column and the running-total chart count every game, so the 60-game 2020 season carries a little over a third of the weight of a full one. Avg finish and the by-season chart count every year equally. A few teams play 161 games in a given year when a rainout is never made up; winning percentage absorbs that.

Franchises, not names. Each row follows a club through relocations and renamings. The Montreal Expos (2000–2004) appear as the Nationals, the Devil Rays as the Rays, the Indians as the Guardians, and the Oakland A's as the Athletics. Divisions shown are today's: Houston played in the NL Central through 2012.

Colors. Each team's color comes from its official palette. With most clubs wearing red or navy, a few shades were nudged lighter or darker, and Arizona appears in the teal it wore in 2001. Text on each cell uses whichever of black or white reads more clearly against it.

Sources and checks. Records and postseason results for 2000–2025 come from the Lahman Baseball Database. Final 2026 standings come from Stats Crew, and 2026 postseason berths follow from them. League-wide wins equal league-wide losses in every season, and the 2026 records for Milwaukee, Los Angeles and Tampa Bay were matched against published reports.

Updated through the end of the 2026 regular season on September 27. The 2026 postseason was still underway at publication, so no 2026 pennant or title is marked.
