The American League Division Series (ALDS) is one of the most exciting and competitive stages of Major League Baseball’s postseason. It serves as the gateway to the American League Championship Series (ALCS), where only the best two teams battle for a shot at the World Series.
But one question continues to pop up every October — how many games must a team win to advance past the ALDS? The simple answer: three. The ALDS is played as a best-of-five series, meaning whichever team wins three games first moves on to the next round.
However, there’s much more to it than just the number of wins. In this guide, we’ll break down how the ALDS works, why the format matters, examples from recent seasons, the importance of home-field advantage, and strategies teams use to clinch those crucial wins.
⚾ What Is the ALDS?
The ALDS (American League Division Series) is part of Major League Baseball’s postseason format. After the Wild Card Series, which is a best-of-three showdown, four teams remain in the American League playoffs:
- The two division winners with the best records.
- The Wild Card Series winners.
These four teams face off in two separate Division Series — each a best-of-five contest. The winners advance to the American League Championship Series (ALCS).
A similar format happens in the National League — known as the NLDS. Together, the ALDS and NLDS determine which two teams will fight for their league’s pennant.
📊 How the ALDS Format Works
The term “best of five” means that the series can last anywhere from three to five games depending on results.
- If a team wins three games straight (3-0) → The series ends immediately in a sweep.
- If it’s 3-1, the series concludes in four games.
- If tied 2-2, a decisive Game 5 is played.
No team can win the series without reaching three victories.
Here’s the official breakdown of the MLB playoff structure as of 2025:
| Round | Format | Number of Wins Needed |
|---|---|---|
| Wild Card Series | Best of 3 | 2 Wins |
| Division Series (ALDS/NLDS) | Best of 5 | 3 Wins |
| Championship Series (ALCS/NLCS) | Best of 7 | 4 Wins |
| World Series | Best of 7 | 4 Wins |
So, in short — to advance from the ALDS, a team must win three games before their opponent does.
🏟️ Home-Field Advantage in the ALDS
Because the ALDS is a short series, home-field advantage plays a significant role. The team with the better regular-season record — also called the higher seed — gets to play more games in front of their home crowd.
Standard ALDS Home-Field Format:
- Game 1: Higher seed (home)
- Game 2: Higher seed (home)
- Game 3: Lower seed (away)
- Game 4: Lower seed (away, if needed)
- Game 5: Higher seed (home, if needed)
This 2-2-1 pattern ensures that the decisive Game 5 (if required) happens on the home turf of the higher-seeded team — a massive psychological and performance boost.
Why it matters:
- Familiarity with the stadium and conditions.
- Energized by local fans.
- Home-team batting advantage (last at-bat).
In a best-of-five series, even a single home game can change the entire outcome.
🔢 How Many Ways Can the ALDS Play Out?
Since it’s a five-game maximum series, there are only a few possible outcomes. Let’s look at how they unfold:
| Series Outcome | Game Count | Description |
|---|---|---|
| 3–0 | 3 Games | Sweep – one team dominates, series ends early. |
| 3–1 | 4 Games | Strong Win – opponent takes one game but loses overall. |
| 3–2 | 5 Games | Full Series – both teams fight to the final game. |
These outcomes depend heavily on pitching rotations, injuries, bullpen stamina, and momentum. Many classic ALDS showdowns — like Yankees vs. Guardians or Astros vs. Twins — have gone to the full five games, keeping fans glued to their seats.
⚙️ Examples from Recent ALDS Seasons
2024 ALDS
In 2024, the ALDS gave fans everything — from quick sweeps to nail-biting Game 5 thrillers.
- One matchup ended 3–1, with the favorite sealing the deal early.
- Another stretched to 3–2, showing how evenly matched teams can push the series to the brink.
2025 ALDS
The 2025 season kept the same structure. Both matchups required three wins to advance, though one team swept in three straight while another won in a hard-fought Game 5.
This consistency across seasons highlights how three wins remains the magic number, no matter the year.
🧠 Strategy: Why Every Game Matters
In a short series like the ALDS, each game carries enormous weight. There’s no room for sluggish starts or sloppy plays. A single mistake — a misjudged pitch, a bullpen meltdown, or a bad call — can tilt the entire series.
Here’s why teams take the ALDS so seriously:
1. Pitching Rotation Management
Teams often start their ace pitchers early in the series to establish momentum.
However, with only five games, managers must balance rest days and bullpen fatigue carefully.
2. Offensive Adjustments
Since opponents face the same pitchers multiple times, hitters must adapt fast — adjusting timing, stance, or pitch selection.
3. Bullpen Usage
Relievers are vital. A tired bullpen can cost critical innings. Teams often save their elite closers for high-leverage moments rather than predictable save situations.
4. Home Advantage Maximization
Winning both home games to start (Games 1 & 2) can make life easier. Losing early at home puts tremendous pressure when traveling.
5. Momentum Is Everything
Even though a team might lose Game 1, a comeback in Game 2 can flip morale completely. Baseball is as much psychological as it is statistical.
🔥 Why the “Three Wins” Format Works
The ALDS format — best of five — strikes a perfect balance between intensity and fairness. Here’s why it’s ideal:
- Keeps every game meaningful: There’s no wasted matchup or “dead rubber.”
- Rewards consistent teams: Winning three games shows stability, not luck.
- Reduces fatigue: Unlike a best-of-seven, it prevents excessive player wear early in the postseason.
- Encourages tactical brilliance: Managers must be sharp with pitching, lineups, and substitutions.
In essence, the best-of-five format creates drama without dragging out the series.
🏆 What Happens After the ALDS?
Once a team secures three wins, they advance to the American League Championship Series (ALCS) — a best-of-seven showdown.
The ALCS winner earns the title of American League Champion and moves on to the World Series, where they face the National League Champion for baseball’s ultimate crown.
Winning the ALDS is not just about moving forward — it’s about momentum. Teams that dominate in the ALDS often carry that energy into deeper playoff rounds.
