what you need to know about the MLB Playoffs
These are the postseason tournament that takes place at the conclusion of each year’s regular season.
What decides who is going to be crowned as the champion of Major League Baseball? Unlike the regular season, where each team gets 162 games, the tournament ensures that just the best teams in the league get into the postseason.
Every game in the playoffs matters even more, since you don’t want to lose momentum on your way to elimination. And finally, the postseason culminates in the most exciting part of the year—the World Series! It’s where the winners of both leagues face off for baseball’s biggest prize!
Understanding MLB’s League Structure
We’re getting there. Before diving headfirst into what happens during the playoffs, let’s first explore how the league itself is set up.
There are 30 total teams in Major League Baseball (MLB). They’re split between two leagues:
- American League (AL)
- National League (NL)
Each league includes 15 teams, which are further broken down into three divisions:
- East
- Central
- West
All through the regular season, teams try to get the best possible record in their divisions while trying to land themselves in one of these coveted Wild Card positions. At the conclusion of the regular season, team rankings will be set, determining who gets into the post-season.

How Many Teams Make the MLB Playoffs?
The number of teams that make the MLB Playoffs is twelve (12).
Each league sends six teams:
- Three division winners
- Three Wild Card teams
This means:
- 6 American League teams
- 6 National League teams
Together these teams will make up the 12 team postseason bracket.
This change expands the number of teams that have a chance at competing for the championship but also makes the last few weeks of each team’s regular season more interesting.
How Do Teams Qualify for the MLB Playoffs?
There are two different ways teams can qualify for the MLB Playoffs.
-
Win Their Division
There are 3 divisions in every league. The team with the best regular season record in each division will qualify for the playoffs as automatic qualifiers known as division champions.
Why does winning your division matter? Primarily, of course, it means you’re getting a better seed into the playoffs (and if you’re one of those at the very top, even a first round bye).
-
Earn a Wild Card Spot
Non-division-winning teams get a shot at playing in the post-season. Three of these teams—those who didn’t win their own divisions but have the best records in their leagues—are awarded a spot on the “Wild Card” team—their season ends if they lose the first two games against another non-division winner in an attempt to make the world series.
This Wild Card system keeps more teams in the postseason mix during the course of their regular seasons and elevates competition across the league.
What Is the MLB Wild Card Series?
This has been one of the biggest changes to the modern MLB postseason format: instead of having each playoff team automatically moving on to the Division Series, they now have to play an opening round against a lower seed.
The Wild Card Series features:
- The winner of the No. 3 division will face off against the No. 6 Wild Card.
- The No. 4 Wild Card will host the No. 5 Wild Card.
- All games are a best-of-three series.
- The higher seed has the right to host all games for a huge home-field advantage.
Winners go on to the Division Series. Losers get eliminated.
How does MLB playoff seeding work?
I know you’re excited to find out how this works! Let’s dive right into it without further ado…
Once the regular season concludes, we’ll seed the teams based on how well they did.
In each league:
- Seed 1 – Best division winner
- 2 – Second best division winner
- 3 – Third division winner
- 4 – Best Wild Card team
- 5 – Second Wild Card team
- 6 – Third Wild Card team
Also, please note that the first and second best teams from each of the leagues get some sweet rewards as well. Not only are they guaranteed spots in the post season (if their divisions allow), but they will also bypass the wild card round, going straight into the division series.
The incentive creates an added reason for competing for better regular-season records rather than just getting into the playoffs.

MLB Playoff Bracket Explained
In contrast to other tournaments where teams get reseeded at every stage of the competition, the MLB postseason is played out on an unchanging bracket. Winners progress around the bracket as they win games, with only one team remaining from each league in the end.
The bracket works like this:
Wild Card Series
- Seed 3 vs. Seed 6
- 4 vs. 5
Division Series
- Seed 1 vs. Wild Card winner
- Seed 2 vs. Wild Card winner
League Championship Series
The two remaining teams compete for the league championship.
World Series
American League Champion VS National League Champion Bracket:
We have made sure that this bracket will allow all our dear fans to easily keep up with what every team is doing towards making it to the championship.
What Is the Division Series?
The Division Series, also known as the DS for short, marks the second round of the MLB playoffs after the conclusion of the Wild Card Series. The top two seeds make their way into the postseason here.
All Division Series are contested as best of five series.
The first team to clinch three games progresses further into the playoffs.
Because the matchups will typically include the top squads in baseball, these series can be intensely competitive contests between division champions and Wild Card winners.
Given that this series is lengthier compared to the Wild Card round of games, we will see much greater reliance placed on teams’ starting pitching rotations and bullpens as well as their offensive consistency.
Why Finishing With a Top Seed Matters
Winning your division (and finishing with one of the league’s two best records) provides multiple key advantages.
Top-seeded teams receive:
- A first round bye
- More time off prior to the Division Series
- Home field advantage during the Division Series
- Shorter path to the World series
All of these rewards are given because of how well you play over those 162 games.

What is the LCS?
After the Division Series, there are two teams left standing in each league that move on to compete in the League Championship Series (LCS):
- American League Championship Series (ALCS)
- National League Championship Series (NLCS)
How does LCS work? The LCS determines which team will be representing their respective leagues in the World Series.
In addition to being a single elimination format, the LCS takes place during a best-of-seven series where the first team to claim victory wins their league’s title.
Every year, this stage of the postseason showcases many of baseball’s most prominent players with some of the fiercest rivalries in sports. In essence, everyone gets a shot at glory.
What Is the World Series?
The World Series is the championship round of Major League Baseball.
Once the American League and National League champions have been decided, these two teams compete head-to-head in a best-of-seven series to crown an MLB champion.
Whoever wins four games first will be considered the World Series Champion.
There is no greater honor for a pro ball player than winning their teams’ bid to claim the World Series title.
This series culminates months worth of games from Spring Training all the way to the grueling 162-game regular season.
A handful of baseball’s greatest moments have occurred during these World Series showdowns.
Home-Field Advantage in the MLB Playoffs
It should be noted that home field does play an integral part when considering these games as they will often have teams hosting their own games based upon their overall regular season standing (the team with the best record gets to host the most games).
Wild Card Series
- Higher-seeded team host all 3 games
- Division Series, League Championship Series, and World Series
These rounds follow the traditional 2-2-1 (best-of-five), or 2-3-2 (best-of-seven) home-and-away format.
Hosting more games can provide several advantages:
- Playing under familiar conditions.
- Getting the support of their home fans.
- Less travel.
- Better comfort and routine.
While having home field advantage is a benefit to most baseball teams, we have seen through baseball history how even a team with a lower seed can come back to upset a favorite team.
Can Wild Card Teams Win the World Series?
Yes! We’ve had several teams qualify for the post-season via Wild Card who ended up winning the World Series themselves. So no, having your spot determined by the Wild Card doesn’t mean you can’t be the best overall!
When the playoff begins, all teams are after one thing – and that’s victory in each series they play.
In fact, there’s no guarantee that even teams with a stellar pitching staff, timely hitting and consistent defense will get too far into the playoffs. It makes for exciting baseball because of its unpredictability, which is why I personally love watching MLB in October.
When do the playoffs start?
The MLB Playoffs typically start around early October, right after the conclusion of their regular season.
How long does the MLB Playoffs last? Generally speaking, the play-offs will last for roughly 1 month (ending in either late-Oct or early-Nov) when the final games are played to determine who wins the World Series!
Of course, this will vary from one season to another depending on things such as travel days, bad weather delaying games, or just how many games are required for a particular playoff series.
Why Are the MLB Playoffs So Exciting?
That’s why so many baseball fans love October – it truly is the best month of the year!
In contrast, all games matter during the playoffs as they play out over several days. Here’s why we love baseball’s MLB Playoffs:
- All playoff games carry tremendous significance since they may affect your favorite team’s chances of winning a championship.
- The best MLB pitching talent comes together for high-stakes showdowns that test their skills under pressure.
- Each walk-off hit has an amazing impact on the storyline that keeps us entertained throughout the season.
- Baseball historic rivals have an electric energy when it comes time to square off again in the postseason.
- A surprise contender defeating a perennial favorite creates one of the most exciting scenarios possible in sports.
- Finally, no matter which side you’re cheering for, watching the playoffs gets everyone ready for the World Series!
Postseason offers a unique combination of strategy, pressure and excitement rarely seen at other sporting events.
MLB Regular Season vs. MLB Playoffs
Although they are connected, the regular season and postseason serve different purposes.
| Regular Season | MLB Playoffs |
|---|---|
| 162 games per team | Multiple elimination series |
| All 30 teams compete | Only 12 teams qualify |
| Determines standings | Determines the champion |
| Focus on long-term consistency | Focus on winning each series |
| Every game counts toward qualification | Every loss brings a team closer to elimination |
The regular season rewards consistency over six months, while the playoffs reward teams that perform at their best under pressure.
