Are there 32 MLB teams?
How many teams are in the MLB?
Major League Baseball has exactly 30 teams in 2025. The league is split into two leagues of 15: the American League and the National League, each with three divisions (MLB.com (official standings)). The 2025 team list includes every franchise from the Arizona Diamondbacks to the Washington Nationals, covering all 30 clubs (Baseball-Reference team index).
Why do some people think there are 32?
The confusion often comes from the fact that the NFL and NBA each have 32 teams. MLB has discussed expansion for years, but as of 2025, no official plan has been announced (Wikipedia expansion history). Some fans also point to the 32 All-MLB selections in 2025, but that’s a postseason honor, not a team count (MLB.com (2025 All-MLB teams)).
Expansion to 32 teams would require adding two new franchises, which would be a multi-year process. No timeline has been set, and the current 30-team structure remains stable.
Why is 42 banned in MLB?
What is the significance of number 42?
Number 42 is permanently retired across all Major League Baseball teams in honor of Jackie Robinson, who broke the sport’s color barrier in 1947. The league-wide retirement was enacted in 1997, the 50th anniversary of Robinson’s debut (MLB.com official retirement policy).
Who was the last player to wear 42?
Players who were already wearing 42 before 1997 were allowed to keep it until they retired. The last active player to wear 42 was Mariano Rivera, the legendary New York Yankees closer, who retired in 2013 (MLB.com historical coverage). Since then, no new player has been issued the number.
The 42 retirement is a rare league-wide honor — no other number has been universally retired. It’s a permanent reminder of Robinson’s impact on the game and society.
Who is the richest MLB team?
How are MLB teams valued?
Forbes regularly publishes estimated valuations for MLB franchises based on revenue, stadium economics, market size, and brand strength. The 2026 update placed the New York Yankees at the top with a valuation of $7.5 billion (Sports Illustrated valuation context).
Top 5 most valuable teams
While the Yankees lead, the Los Angeles Dodgers, Boston Red Sox, Chicago Cubs, and San Francisco Giants also command billion-dollar valuations. The gap between the richest and smallest-market teams is substantial, driven largely by local TV contracts and stadium revenues (Baseball-Reference team history).
Who got banned from MLB for life?
What did Tucupita Marcano do?
In 2024, the league issued a lifetime ban to Tucupita Marcano, then a player for the San Diego Padres, for betting on MLB games. The investigation found he placed bets on games involving his own team, violating the league’s strict gambling policy (Sports Illustrated gambling ban).
Other lifetime bans in MLB history
Pete Rose, the all-time hits leader, was banned for life in 1989 after an investigation found he bet on games while managing the Cincinnati Reds. Shoeless Joe Jackson was banned in 1920 for his involvement in the Black Sox Scandal, though he was acquitted in court. These three cases represent the most famous lifetime bans for gambling (Wikipedia historical bans).
How many MLB teams make the playoffs?
Current playoff format
As of 2022, the playoff format expanded from 10 to 12 teams. Six teams from each league advance: the three division winners and three wild-card teams (MLB.com standings context). The wild-card round is a best-of-three series, followed by the Division Series, League Championship Series, and World Series.
How many teams per league?
Each league sends six teams: three division winners (seeded 1-3) and three wild-card teams (seeded 4-6). The two division winners with the best records get a bye to the Division Series, while the remaining four teams play in the wild-card round (Baseball-Reference 2025 league structure).
The 12-team format gives more teams a path to the postseason, but it also reduces the value of a division title — the top two seeds get a bye, while the third division winner must play in the wild-card round.

Is the number 69 banned in MLB?
No, the number 69 is not officially banned by MLB rules. However, it has never been worn by a player in a regular-season game, likely due to social stigma. The league does not have a formal list of prohibited numbers.

Quotes and perspectives
“The New York Yankees are the gold standard of franchise valuation, with a brand that transcends baseball.”
Forbes (team valuations)
“The retirement of 42 across all of baseball is a permanent tribute to Jackie Robinson’s courage and impact.”
MLB.com (official league coverage)
“Tucupita Marcano’s lifetime ban sends a clear message: betting on baseball will not be tolerated.”
CBS Sports (Marcano report)
“MLB’s 30-team structure has remained unchanged since 1998, making it one of the most stable professional sports leagues.”
Wikipedia (Major League Baseball overview)
The 30-team league is a result of decades of careful expansion and relocation. For the New York Yankees, the richest team, the path forward is about maintaining dominance. For smaller-market clubs, the challenge is competing in a system where revenue disparities are wide. The implication for fans: the 30-team era is likely to continue for the foreseeable future, with expansion talk remaining just talk.
