1891 Boston Reds season
The 1891 Boston Reds baseball team finished the season with a 93–42 record and won the American Association championship in their first season in the new league after the demise of the Players' League. Thus they became only the second team to win championships in two different leagues in successive seasons, as well as the only team to win the pennant every single season of its existence. After the season, the AA also disbanded, and the Reds team folded with the league.
