Each Major League Baseball (MLB) team plays 162 games in a regular season, typically running from late March or early April through September. This totals 2,430 games league-wide across both the American and National Leagues.
The Structure of an MLB Regular Season
The 162-game schedule has been standard since 1961 for the American League and 1962 for the National League. Each team's season is divided into home and away games, with matchups distributed across divisional opponents, interleague play, and teams within the same league but different divisions.
Distribution of Games
MLB teams do not play each opponent equally. The current scheduling format, updated in 2023 to accommodate the addition of an interleague rivalry series, follows a balanced yet strategic structure:
- 13 games against each of 4 division rivals (52 games)
- 6 games against each of 10 teams in own league, outside division (60 games)
- 6 games against a rotating interleague opponent (6 games)
- 4 games against each of 4 designated interleague rivals (20 games)
- 20 additional interleague games against remaining 15 teams (one series each)
Historical Evolution of the MLB Schedule
The number of games in a season has evolved over time as the league expanded and restructured:
- 1904–1960: 154 games per team
- 1961–present (AL): 162 games after expansion to 10 teams
- 1962–present (NL): 162 games adopted after expansion
- 1997: Introduction of interleague play (1-2 games per team)
- 2023: New format increases interleague games to around 46 per team
Impact of Scheduling on Player Performance and Team Strategy
The length and structure of the MLB season influence player rest, rotation strategies, and injury management. With nearly daily games, managers rely heavily on five-man pitching rotations and active roster management.
Key Factors Influenced by Game Volume
- Injury risk due to repetitive stress
- Bullpen usage and pitcher workload
- Travel fatigue, especially on West Coast-East Coast trips
- Opportunities for comeback after slow starts
| Season Year | Total Teams | Games per Team | Total Regular Season Games | Notable Change |
|---|---|---|---|---|
| 1950 | 16 | 154 | 1,232 | Pre-expansion era |
| 1962 | 20 | 162 | 1,620 | NL adopts 162-game season |
| 1998 | 30 | 162 | 2,430 | Expansion to 30 teams |
| 2020 | 30 | 60 | 900 | Pandemic-shortened season |
| 2023 | 30 | 162 | 2,430 | New interleague format |
The data shows consistency in the 162-game standard since the 1960s, with only rare exceptions like the 2020 shortened season. The total number of games scales with league size, reaching 2,430 annually with 30 teams. The 2023 update increased interleague variety without altering the total game count.
