Other teams
Several 19th century teams played .700 ball or better over shorter schedules, where there is much less of the "evening out" effect of a lengthier season. The 1876 Chicago White Stockings won the National League's first pennant with a 52-14 record (.788). Chicago won the 1880 NL pennant with a record of 67-17 (.798), which stands as the overall percentage record between the National or the American League, and would project to a record of 129-33 under the modern schedule of 162 games.

The all-time best single season record belongs to the St. Louis Maroons of the 1884 Union Association. Playing in a league that lasted only one season and was quite lopsided in talent distribution, and generally disorganized (six teams played close to full schedules while six more came and went during the course of the year), the Maroons went 94-19 (.832), or the equivalent of 134-28 under the modern schedule. The Maroons joined the National League for 1885 and, playing against stiffer competition, went 36-72.
