Major League Baseball (MLB) teams play 162 games during a standard regular season. Across the entire league, 30 teams combine to play a total of 2,430 regular-season games every year from late March or early April through late September. This marathon schedule is the longest in professional team sports, dwarfing the 82 games of the NBA and NHL, and the 17 games of the NFL.
Understanding why the schedule is set at this exact length requires looking at modern scheduling rules, historical evolution, and the unique math behind baseball analytics.
The Structure of the 162-Game Schedule
How those 162 games are distributed changed significantly with a balanced schedule overhaul. MLB teams don't just play their local rivals anymore; the league uses a universal schedule where every team plays every other team across both the American League (AL) and National League (NL).
- Divisional Opponents: Each team plays 52 games against opponents in its own division (13 games against each of the other four teams).
- Intraleague Opponents: Teams play 64 games against other teams in their own league outside their division.
- Interleague Opponents: Teams play 46 games against opponents in the opposing league, including a designated natural rival series and home-and-home matchups across the rest of the league.
This distribution ensures that fans in every ballpark get to see every visiting team and star player at least once a year, balancing regional rivalries with broader cross-country exposure. More journalism by Bleacher Report delves into similar views on this issue.
Why Does MLB Play 162 Games?
The long season isn't an arbitrary choice. It serves a specific mathematical and operational purpose for players, managers, and statisticians.
Baseball is a sport with high variance on a daily basis. Even the worst teams in baseball win roughly 30 percent of their games, and the best teams rarely win more than 70 percent. A 162-game sample size smooths out short-term luck, cold streaks, and random fluctuations. It ensures that the teams advancing to the postseason are genuinely the strongest over six months, rather than squads that caught a hot streak for a few weeks.
Statisticians and front offices rely on this large sample size. A batting average or earned run average (ERA) accumulated over 162 games gives an accurate picture of a player's true skill level. Shorter seasons introduce too much statistical noise, making it difficult to evaluate talent accurately or negotiate multi-year player contracts.
A Short History of Schedule Length
The 162-game standard wasn't always baseball's norm. In the early decades of professional baseball, schedules fluctuated wildly based on travel logistics, team counts, and economic conditions.
During the late 19th and early 20th centuries, teams played anywhere from 70 to 140 games. By the 1900s, the schedule stabilized at 154 games per team in an eight-team league format.
Everything changed in 1961. The American League expanded from eight teams to ten, adding the Los Angeles Angels and Washington Senators. To accommodate a balanced schedule with ten teams playing a double round-robin, the schedule expanded from 154 games to 162 games. The National League followed suit in 1962 when it also expanded to ten teams. Aside from labor strikes (such as in 1981 and 1994) and the pandemic-shortened 2020 season, the 162-game schedule has remained untouched for more than six decades.
Postseason: Games Beyond the Regular Season
For teams that qualify for the playoffs, the season extends well beyond 162 games. Depending on how deep a franchise runs into October, a championship team can play up to 13 additional postseason games:
- Wild Card Series: A best-of-three series.
- Division Series: A best-of-five series.
- League Championship Series: A best-of-seven series.
- World Series: A best-of-seven series.
When factoring in spring training (roughly 30 exhibition games in February and March) and a deep playoff run, a Major League baseball player can easily log nearly 200 games in a single calendar year. You can track current standings and schedules directly on the Official MLB Website.
Common Mistakes When Counting Baseball Games
People outside the sport often make a few predictable errors when looking at baseball calendars.
- Confusing total league games with team games: There are 2,430 total regular-season games played in a year, but an individual team only plays 162 of them.
- Assuming every player appears in every game: Playing all 162 games in a season—known as "Club 162"—is exceptionally rare. Modern sports science and load management mean managers routinely rest everyday starters to prevent injuries, so roster depth is critical.
- Overlooking minor league variations: Minor League Baseball (MiLB) operates under different schedules. Triple-A teams play 150 games, Double-A teams play 138 to 140 games, and lower-tier leagues play even fewer.
Frequently Asked Questions
What happens if a regular-season game is rained out?
If a game is postponed due to weather and hasn't reached official status (five completed innings, or four and a half if the home team is winning), it's completely replayed from the start later in the year. These are frequently made up during doubleheaders—two games played on a single day.
Do players get paid for the 162-game season?
Player salaries are contracted as a flat annual amount covering the 162-game regular season, regardless of how many games an individual appears in. However, players earn performance bonuses and shares of a lucrative postseason player pool if their team reaches the playoffs.
How do travel schedules work over 162 games?
Teams travel primarily by charter flights rather than trains or buses. To minimize fatigue, the league schedules games in multi-game series—typically hosting three to four-game homestands or road trips against the same opponent before moving to the next city.
Are there plans to shorten the MLB season?
While fans and analysts occasionally debate whether 162 games are too grueling, league leadership and team owners show little interest in reducing the schedule. Ticket sales, local television broadcasts, stadium concessions, and historic record-keeping are all tied directly to the 162-game structure.
