The American League Championship Series (ALCS) is one of Major League Baseball’s most competitive and high-stakes matchups. It determines which American League team advances to the World Series, facing off against the National League Champion. But one of the most common questions fans ask every postseason is: “How many games are in the ALCS?”
The answer isn’t just a number it’s a story of strategy, endurance, and timing that defines the modern MLB playoff system. Let’s break it down in detail, including the structure, recent rule changes, and what fans can expect from the 2025 ALCS.
How Many Games Are in the ALCS?
The ALCS is a best-of-seven series. That means:
-
The first team to win four games advances to the World Series.
-
The series can last anywhere from four to seven games, depending on how evenly matched the teams are.
This format has been in place since 1985, when MLB expanded the League Championship Series from a best-of-five to a best-of-seven format similar to the World Series.

The 2-3-2 format gives the higher-seeded team typically the one with the better regular-season record a slight edge with home-field advantage in four out of seven games.
Why MLB Uses a Best-of-Seven Format
The ALCS format isn’t random it’s designed to balance competition and reduce flukes.
-
Fairer outcome: A best-of-seven series ensures that one or two bad games don’t eliminate the better team.
-
Strategic depth: Teams must manage pitchers, bullpen rotations, and rest days smartly.
-
Fan engagement: The longer format builds tension, boosting TV ratings and stadium attendance.
According to MLB postseason data from recent years (2023–2024), over 55% of ALCS series have gone at least six games, showing just how closely matched elite teams usually are.
How Long Does the ALCS Last?
Since it’s a potential seven-game series, the ALCS typically lasts 7–9 days, depending on travel and rest days.
For example, the 2024 ALCS spanned from October 13 to October 22, with one travel day between games 2 and 3 and another between games 5 and 6.
This structure ensures fair rest for pitchers and allows teams to travel coast-to-coast if necessary such as a matchup between the Texas Rangers and New York Yankees.
ALCS 2025: What to Expect
As of 2025, the MLB postseason calendar keeps the same structure, with the ALCS following the Division Series (ALDS).
-
Projected Dates: Mid to late October 2025
-
Home Advantage: Decided by regular-season record, not seeding alone
-
Broadcast: FOX and FS1 continue exclusive coverage
Expect teams like the Yankees, Orioles, and Astros to remain strong contenders based on current roster depth and offseason analytics.
Expert Insight:
The shift toward advanced bullpen management and pitch clock efficiency in 2024–2025 has reduced overall game times, but the strategic chess match in the ALCS remains as intense as ever. Managers now balance analytics-driven decisions (e.g., matchups based on spin rate data) with old-school instincts about momentum and player stamina.
Why the ALCS Format Matters for Teams
A seven-game structure doesn’t just test skill it tests adaptability.
Strategic Implications:
-
Pitching rotation management: Teams usually use four starters in rotation, but some opt for a three-man rotation with bullpen support.
-
Momentum shifts: Winning the first two home games can set the tone, but history shows several comebacks from teams trailing 3–1.
-
Psychological edge: Game 6 and Game 7 pressure often brings out elite clutch performances — like the 2023 Rangers, who overcame a tough deficit to clinch Game 7 on the road.
ALCS vs. Other MLB Playoff Series
Series |
Format |
Purpose |
|---|---|---|
Wild Card Series |
Best-of-3 |

Division Series (ALDS) |
Best-of-5 |
Determines who goes to ALCS |
ALCS / NLCS |
Best-of-7 |
Determines league champion |
World Series |

Compared to the shorter Wild Card and Division Series, the ALCS’s seven-game format rewards consistency. Teams with depth especially in pitching and bench strength tend to thrive.
