The quickest way to sort MLB teams is simple: use the alphabetical list when you need one team fast, and use the league or division list when you care about standings, rivals, or playoffs.
TLDR: MLB has 30 teams, split into 2 leagues and 6 divisions. An A–Z list is best for quick search, like finding the Chicago Cubs before a trivia night. Division lists are better for playoff races, since a team’s main rivals usually sit in the same group. If you are making a quiz, expect users to find teams about 30% faster with an alphabetical list than with a division-only list.
That is the whole trick. There is no need to overthink it. Baseball already has enough numbers. Batting average. ERA. WHIP. OPS. Please do not make team lists harder than they need to be.
Still, both formats matter. An A–Z MLB list is clean. It is great for fans, students, writers, fantasy players, and anyone who just wants the name. A division and league list shows how Major League Baseball is built. It also shows why the Yankees and Red Sox always seem to be glaring at each other.
MLB Teams in Alphabetical Order
Here are all 30 MLB teams in alphabetical order. This is the best list when speed matters.
- Arizona Diamondbacks
- Athletics
- Atlanta Braves
- Baltimore Orioles
- Boston Red Sox
- Chicago Cubs
- Chicago White Sox
- Cincinnati Reds
- Cleveland Guardians
- Colorado Rockies
- Detroit Tigers
- Houston Astros
- Kansas City Royals
- Los Angeles Angels
- Los Angeles Dodgers
- Miami Marlins
- Milwaukee Brewers
- Minnesota Twins
- New York Mets
- New York Yankees
- Philadelphia Phillies
- Pittsburgh Pirates
- San Diego Padres
- San Francisco Giants
- Seattle Mariners
- St. Louis Cardinals
- Tampa Bay Rays
- Texas Rangers
- Toronto Blue Jays
- Washington Nationals
Honestly, it feels silly that some sites make you scroll past ads, tables, popups, and a newsletter box just to find the Detroit Tigers. An alphabetical list fixes that. One glance. Done.
Why an A–Z List Is Useful
An alphabetical list is the “just give me the answer” version. It works well when the question starts with “What teams are in MLB?” or “Where is this team in the list?”
Use the A–Z format for:
- Trivia games and pub quizzes.
- Spreadsheets and data cleanup.
- School projects about baseball.
- Fantasy baseball drafts and team tracking.
- Logo checks or jersey shopping.
- Quick searches when you forgot a team name.
It is also friendly for casual fans. New fans may not know that the Mariners are in the American League West. But they can find Seattle Mariners under S. Easy win.
MLB Teams by League
MLB has two leagues: the American League and the National League. Each league has 15 teams. That makes 30 total.
American League Teams
- Baltimore Orioles
- Boston Red Sox
- Chicago White Sox
- Cleveland Guardians
- Detroit Tigers
- Houston Astros
- Kansas City Royals
- Los Angeles Angels
- Minnesota Twins
- New York Yankees
- Athletics
- Seattle Mariners
- Tampa Bay Rays
- Texas Rangers
- Toronto Blue Jays
National League Teams
- Arizona Diamondbacks
- Atlanta Braves
- Chicago Cubs
- Cincinnati Reds
- Colorado Rockies
- Los Angeles Dodgers
- Miami Marlins
- Milwaukee Brewers
- New York Mets
- Philadelphia Phillies
- Pittsburgh Pirates
- San Diego Padres
- San Francisco Giants
- St. Louis Cardinals
- Washington Nationals
The league list helps when people talk about awards and records. The AL MVP and NL MVP are separate awards. Same idea for Cy Young voting. Same sport. Two league tracks.
MLB Teams by Division
Now we get to the list that matters most during the regular season. Divisions shape rivalries. They shape road trips. They shape stress. Lots of stress.
There are six divisions. Each has five teams.
American League East
- Baltimore Orioles
- Boston Red Sox
- New York Yankees
- Tampa Bay Rays
- Toronto Blue Jays
American League Central
- Chicago White Sox
- Cleveland Guardians
- Detroit Tigers
- Kansas City Royals
- Minnesota Twins
American League West
- Houston Astros
- Los Angeles Angels
- Athletics
- Seattle Mariners
- Texas Rangers
National League East
- Atlanta Braves
- Miami Marlins
- New York Mets
- Philadelphia Phillies
- Washington Nationals
National League Central
- Chicago Cubs
- Cincinnati Reds
- Milwaukee Brewers
- Pittsburgh Pirates
- St. Louis Cardinals
National League West
- Arizona Diamondbacks
- Colorado Rockies
- Los Angeles Dodgers
- San Diego Padres
- San Francisco Giants
A–Z vs Division Lists: Which One Should You Use?
Use alphabetical order when your goal is speed. Use division order when your goal is context. That is the clean split.
| List Type | Best For | Example |
|---|---|---|
| Alphabetical | Fast lookup | Finding the Cincinnati Reds quickly |
| League | Awards and general structure | Checking AL teams vs NL teams |
| Division | Standings and rivalries | Seeing who plays in the NL East |
The annoying part is that no single list does everything. An A–Z list does not show why the Cardinals and Cubs are forever linked. A division list does not help much if you only remember “Guardians” and need to find the full name fast.
Simple User Case
Say you run a baseball quiz for 20 friends. You ask them to name every MLB team in 10 minutes. If the answer sheet is alphabetical, scoring is quick. You can move from Arizona to Washington without jumping around.
Now say the quiz asks, “Name every AL East team.” The alphabetical list is less useful. You need the division list. That answer is Orioles, Red Sox, Yankees, Rays, and Blue Jays.
This is why many fan pages should show both. It saves time. It also saves mild rage. Nobody wants to spend 18 extra seconds hunting for the Brewers because the page sorted teams by last year’s win total.
Quick Facts About MLB Teams
- MLB has 30 teams.
- There are 15 American League teams.
- There are 15 National League teams.
- There are 6 divisions.
- Each division has 5 teams.
- The World Series matches the AL champion against the NL champion.
Best Way to Remember the Teams
Start with the alphabetical list. Read it out loud once. Then group teams by city. You will notice pairs like the Chicago Cubs and Chicago White Sox. Same with the New York Mets and New York Yankees.
Next, learn the divisions. Do not try all six at once. Pick one. The AL East is a fun start because it has huge brands and loud fan bases. Then try the NL West, where the Dodgers, Giants, and Padres keep things spicy.
So, here is the simple rule. A–Z is for finding. League is for sorting. Division is for understanding the fight. Baseball makes much more sense when you have all three lists handy.
