Every Major League Baseball team plays 162 games during the regular season. Spanning roughly six months from late March to late September, this massive schedule makes baseball the longest regular season in professional sports. With 30 teams competing, the league generates a staggering 2,430 total games every year, creating a daily grind that tests roster depth, physical endurance, and mental toughness unlike any other sport.
Understanding why the schedule is so long requires looking at how those 162 games are divided, why the league adopted this specific number, and how it compares to other major leagues.
How the 162-Game Schedule is Built
The modern MLB schedule isn't random. Since a major format shift, every team plays a balanced schedule that ensures every franchise faces every other team across both the American League and National League. The 162 games break down into three primary categories:
- Divisional Play (52 games): Teams play 13 games against each of their four division rivals. These matchups form the core of the pennant race.
- Intraleague Play (64 games): Teams play six games against six opponents in their league and seven games against the remaining four league opponents.
- Interleague Play (46 games): Every team plays a standard series against teams from the opposite league, including a natural geographic rival.
This structure ensures that teams don't just beat up on weak division opponents; they face a standardized test against the entire league. Home and away games are split evenly, with each team playing 81 games at home and 81 on the road.
Why Does MLB Play 162 Games?
The short answer is a mix of history, economics, and statistical fairness. Baseball is a sport defined by high variance. A bad bounce, a missed call, or a single brilliant pitching performance can swing any given game. In a short season, fluke wins and losses dictate standings. Over 162 games, those statistical anomalies smooth out, allowing the genuinely superior teams to rise to the top.
Financially, baseball relies heavily on ticket sales, local broadcast rights, and stadium concessions. More games mean more revenue opportunities for team owners, higher player payroll funding, and steady daily engagement for fans who want a game to watch every evening.
The Historical Evolution to 162
Baseball hasn't always played 162 games. In the late 19th and early 20th centuries, schedules fluctuated wildly between 70 and 140 games as franchises stabilized. By 1904, the American and National Leagues settled on a 154-game schedule, which lasted for decades.
The shift to 162 games happened in 1961. When the American League expanded from eight teams to ten by adding the Los Angeles Angels and the new Washington Senators, the league needed a schedule that accommodated the new team count while keeping total game math clean. Teams played 18 games against each of the nine opponents (9 opponents times 18 games equals 162). The National League followed suit with expansion in 1962. Even as the league expanded further to 30 teams, the 162-game benchmark remained untouched.
How MLB Compares to Other Pro Sports
No other North American professional sports league comes close to the sheer volume of an MLB season. The physical toll of baseball is unique because players compete nearly every single day.
- NFL: Teams play just 17 regular-season games over 18 weeks, allowing a full week of physical recovery between high-impact collisions.
- NBA and NHL: Both leagues play an 82-game schedule over roughly six months, meaning teams frequently play back-to-back games or three games in four nights.
- MLS: Major League Soccer plays a 34-game schedule spread across nine months, typically averaging one match per week.
Baseball's daily cadence means players must manage slumps quickly. A hitter who goes hitless for five games in the NFL has ruined a massive percentage of their season; in MLB, a five-game slump is barely a footnote in a six-month marathon.
The Physical Toll and the "Club 162" Rarity
Playing 162 games in roughly 185 days leaves very few off days. Travel across different time zones, night games followed by day games, and chronic minor injuries test players' durability.
Because of modern sports science and load management, appearing in all 162 games has become exceptionally rare. Managers frequently rest star players to keep them fresh for October. Decades ago, ironmen like Cal Ripken Jr. or Ernie Banks regularly played every single game, but today, seeing a player log a full 162-game season happens only a handful of times league-wide each year.
Frequently Asked Questions
Do Spring Training games count toward the 162-game total?
No. Spring Training consists of exhibition games played in February and March across the Cactus League in Arizona and Grapefruit League in Florida. They do not affect regular-season standings.
What happens if a regular-season game is cancelled?
If a game is rained out and has no bearing on the postseason standings, it might not be made up. However, if the game impacts playoff qualification or seeding, teams will make up the game during a mutual off-day or play a split doubleheader.
How many total games are played in an MLB season including the playoffs?
The regular season accounts for 2,430 games. Depending on how many games are required in the Wild Card, Division Series, League Championship Series, and World Series, the postseason adds roughly 30 to 45 additional games across the qualifying playoff teams.
Has the MLB season length ever been shortened?
Yes, due to labor strikes or global events. Shortened seasons occurred in 1981, 1994, 1995, and 2020, when the schedule was reduced significantly due to negotiations or public health protocols. In a normal operating year, however, 162 remains the golden standard.
