Cincinnati Reds: How rare are 100-loss seasons in Major League Baseball?

How often do teams lose 100 games in the 162-game era?

Since 1961 when the American League adopted the expanded schedule and 1962 when the National League followed suit, six teams never lost 100 games: the Philadelphia Phillies; St. Louis Cardinals; Los Angeles Dodgers; Colorado Rockies; Los Angeles Angels; and New York Yankees.

The other 24 teams have combined for 85 100-loss seasons or an average of about 1.4 per year, though there have been more in recent years. There were four 100-loss teams this season, four last season, four in 2019 and three in 2018 after a four-year stretch (2014-17) with only one 100-loss team.
