You probably think you know the list of Major League Baseball teams by heart. Yankees in the Bronx, Dodgers in Chavez Ravine, and the A's in... wait, where are the A's this week? If you haven't checked the standings lately, things look a little weird.
Baseball is currently in a massive state of flux. We aren't just talking about the 30 teams we've lived with since 1998. We’re talking about a league that is actively stretching its seams, testing new markets, and trying to figure out if it can handle 32 franchises.
It’s a lot to keep track of. Honestly, even the most die-hard fans are starting to get confused by the "temporary" home in Sacramento and the whispers of a "Nashville Stars" jersey hitting the shelves by the end of the decade.
The Current 30: A Breakdown of the Leagues
Right now, the list of Major League Baseball teams remains capped at 30. They are split down the middle—15 in the American League (AL) and 15 in the National League (NL).
The balance is tidy. Each league has three divisions. Each division has five teams. But don't get too comfortable with that symmetry; Commissioner Rob Manfred has basically hinted that as soon as the league expands to 32, this whole five-team-per-division setup is going into the trash can. We're likely looking at a future of eight divisions with four teams each.

American League Teams
The AL is where you find the designated hitter purists (well, until the NL finally caved) and some of the most historic logos in sports.
- AL East: This is the "big spender" zone. You have the New York Yankees, the Boston Red Sox, the Baltimore Orioles, the Toronto Blue Jays, and the Tampa Bay Rays.
- AL Central: Often called the "comedy central" by mean-spirited Twitter fans, but it’s actually a grinder. It’s the Cleveland Guardians, Detroit Tigers, Kansas City Royals, Minnesota Twins, and the Chicago White Sox.
- AL West: This is the most geographically "confused" division. You've got the Houston Astros, Texas Rangers, Seattle Mariners, Los Angeles Angels, and the nomadic Athletics.
National League Teams
The Senior Circuit feels a bit more traditional, even though they finally adopted the DH.
- NL East: A total powerhouse lately. The Atlanta Braves, Philadelphia Phillies, New York Mets, Miami Marlins, and Washington Nationals.
- NL Central: High-density rivalries. Chicago Cubs, St. Louis Cardinals, Milwaukee Brewers, Cincinnati Reds, and the Pittsburgh Pirates.
- NL West: Late-night chaos. Los Angeles Dodgers, San Diego Padres, Arizona Diamondbacks, San Francisco Giants, and the Colorado Rockies.
What’s Going on With the Athletics?
This is the question that breaks the "list" for most people. If you search for the list of Major League Baseball teams in 2026, you won't find the "Oakland" Athletics.
They are officially just the Athletics.

They left the Coliseum after 2024. Now, they are playing their home games at Sutter Health Park in West Sacramento. It's a minor league stadium. Seriously. They are sharing a park with the Sacramento River Cats while they wait for their $2 billion stadium on the Las Vegas Strip to be built.
It’s weird. They play in a 14,000-seat stadium, which is actually a boost in atmosphere compared to the empty concrete cavern they left behind in Oakland. But if you’re looking for them on a map, they are currently a California team with a Nevada future and no city in their official name.
The Expansion Rumors: Who is Next?
The list of Major League Baseball teams hasn't grown since the Diamondbacks and Rays joined the party back in '98. That’s the longest drought without expansion in the modern era.
But it’s coming.

MLB has a plan. They want 32 teams. Why? Because 32 teams makes the schedule way easier to write. It allows for two 16-team leagues or four 8-team divisions. It gets rid of the weird "interleague play every single day" necessity.
The Top Candidates
- Nashville: They’ve already got a name picked out—the Nashville Stars. It’s a nod to the city’s Negro Leagues history. They have the money, the growth, and the "Music City" vibe that MLB is desperate to market.
- Salt Lake City: This is the dark horse that isn't so dark anymore. The Big League Utah group has a massive plan for a "Power District" stadium. With the NHL recently landing in Utah, the momentum here is insane.
- Charlotte: Geographically, it makes too much sense. The gap between Atlanta and DC is huge.
- Portland: The "keep it weird" contingent. They have a loyal fan base, but the stadium funding has always been the sticking point.
Why the "List" Matters for Your Bracket
Honestly, the way the list of Major League Baseball teams is organized right now is probably going to be a relic within five years.
If you're a fan of the "Classic Eight" or the old-school division rivalries, cherish them. We are heading toward a world where geography wins over history. MLB wants to reduce travel times to save players' bodies and—let’s be real—save on jet fuel.
Don't be surprised if the 2030 list looks more like a regional map. You might see a "Pacific Division" that actually only has teams in the Pacific Time Zone, unlike the current AL West that forces Seattle to fly to Houston every other week.
Actionable Insights for Fans
- Check the venue before you travel: If you're planning a trip to see the Athletics, do not go to Oakland. They aren't there. They are in Sacramento (mostly) and playing a few special "home" games in Las Vegas this June.
- Watch the CBA expiration: The current Collective Bargaining Agreement ends in December 2026. This is the "gatekeeper" for expansion. No new teams will be officially announced until the new labor deal is inked.
- Keep an eye on the Rays: While the A's move is settled, the Tampa Bay Rays' stadium situation in St. Petersburg is the final "internal" hurdle before MLB turns the expansion light from yellow to green.
Baseball is changing. The list is growing. It’s a good time to be a fan, as long as you can keep track of where everyone is playing.
