The decision to extend the Major League Baseball season to 162 games represents one of the most significant structural changes in the sport's history. For fans and historians alike, understanding when MLB go to 162 games requires looking back at the early 20th century, when the schedule was in constant flux. The modern standard length was not implemented overnight but was the result of a gradual evolution driven by league expansion, the need for balanced competition, and the pursuit of revenue.
The Pre-162 Era: A Schedule in Flux
For the first several decades of its existence, Major League Baseball operated without a fixed schedule length. In the late 1800s and early 1900s, team schedules could range anywhere from 124 to 154 games, depending on the year and the league. The 154-game schedule became a common standard during the dead-ball era, largely because it was practical for travel and fit within the constraints of the season's calendar. However, this number was never officially codified by the league office, leading to inconsistencies that made comparing teams across different years difficult.
The Push for Consistency
The primary catalyst for the change to 162 games was the exponential growth of the league through expansion. In 1961, the American League added the Los Angeles Angels and moved the Washington Senators to Minnesota, creating the need to integrate these new franchises into the schedule. The National League followed suit in 1962 with the addition of the New York Mets and Houston Colt .45s (later Astros). With more teams in the league, the existing 154-game schedule could not accommodate a balanced structure where each team played an equal number of games against every opponent.
The Birth of the 162-Game Schedule
The transition occurred incrementally, with the American League being the first to adopt the new length. The 1961 season marked the official debut of the 162-game schedule for the AL, a direct result of the eight-team league needing to fill out its calendar. The National League adopted the 162-game format the following year in 1962. This change was not merely an arbitrary number; it was calculated to ensure that teams would play a sufficient number of games to determine a clear winner while managing the grueling physical demands of the sport.
1961: American League expands to 10 teams, adopting a 162-game schedule.
1962: National League expands to 10 teams, following suit with a 162-game schedule.
Result: The 162-game season becomes the standard for the modern era.
Strategic Advantages of the Length
Extending the season to 162 games provided several strategic advantages for the league. From a competitive standpoint, it allowed for a more robust playoff race, creating a greater margin for error and drama down the stretch. The additional games served to dilute the impact of random variance and "bad luck," ensuring that the best team over the long haul typically emerged victorious. Furthermore, from a business perspective, the extra games generated significant revenue through ticket sales, broadcasting rights, and merchandise, solidifying the season's length as a financial necessity.
Enduring Legacy
Despite various discussions about shortening the season due to player fatigue or injury concerns, the 162-game schedule has remained the bedrock of the MLB regular season for decades. It has become deeply embedded in the culture of the sport, shaping everything from roster construction to the statistical benchmarks used to evaluate player performance. While the question of "when did MLB go to 162 games" points to the early 1960s, the legacy of that decision is felt every single day during the long, grueling march to October.
