Regular season record by decade
The number of regular season games scheduled each season has varied over time, from as low as 140 to the current 162, which has been in place since 1961.

Prior to the delayed-start season, when teams played a reduced schedule of 60 games and only faced opponents within their own division, the most recent season during which the Red Sox did not play a full 162-game schedule was 2001, when they played 161 games.
