All 30 MLB teams by win percentage
All 30 teams, ranked on regular-season games won as a share of games played. A franchise’s record is carried through its moves and renamings, so these are the franchise’s figures rather than the city’s.

How this list is made
Teams are ranked on regular-season games won as a share of games played, and on nothing else. Where two are level they share a rank, and the list runs past fifty when fiftieth place is shared, because splitting a tie would mean choosing between them on no stated basis.
A total is not a rate. A club playing since 1871 has had far longer to accumulate wins than one founded in 1998, and the Founded column shows it. Win percentage is the comparison that does not care how long a franchise has existed.
The World Series starts in 1903. A nought in that column for a club older than the competition means it has not won one, not that it was missed.
