Quick Answer
Here is how the World Series works. It is Major League Baseball's championship. The American League champion plays the National League champion in a best of seven series, and the first team to win four games wins the title.
It uses a 2-3-2 format. The team with the better regular season record hosts Games 1, 2, 6 and 7, and the other team hosts Games 3, 4 and 5.
The winner receives the Commissioner's Trophy. Because it is played in October, the series is nicknamed the Fall Classic.
How Do Teams Reach the World Series?
Each league sends six teams to the postseason: the three division winners plus three Wild Card teams with the best remaining records.
The path has four rounds:
- Wild Card Series: best of three. The top two division winners in each league get a bye.
- Division Series: best of five.
- League Championship Series: best of seven. The winner is the league champion, or pennant winner.
- World Series: best of seven between the two pennant winners.
What Is a Best of Seven Series?
The teams play up to seven games. The first to win four takes the series, so a series can end in four, five, six or seven games.
MLB.com notes the World Series has been a best of seven every year since 1922. The first World Series in 1903 was a best of nine, and the format returned briefly from 1919 to 1921.
What Is the 2-3-2 Format?
The series is split by location:
- Games 1 and 2: at the team with home field advantage
- Games 3, 4 and 5: at the other team (Game 5 only if needed)
- Games 6 and 7: back at the first team (only if needed)
There are usually travel days between Games 2 and 3 and between Games 5 and 6.
Who Gets Home Field Advantage?
Since 2017, home field goes to the World Series team with the better regular season winning percentage, whether it won its division or entered as a Wild Card, according to MLB.com.
If the records are tied, the first tiebreaker is the head to head record during the regular season.
It used to be decided differently. For most of history it alternated between the leagues each year. From 2003 to 2016, it went to the league that won the All Star Game.
Does Home Field Really Matter?
It helps a little. The home team bats last and plays in a familiar park with a loud crowd. But many teams have won the title on the road, including in Game 7.
Pitching depth, health and timely hitting usually matter more than location.
Do American League Rules Differ From National League Rules?
Not anymore. Both leagues now use the designated hitter, so pitchers do not bat in any World Series game. Before the universal DH began in 2022, the home team's league rules applied.
Modern rules like the pitch clock and the larger bases apply in the postseason too.
What Happens if a Game Goes to Extra Innings?
Postseason games, including the World Series, play full extra innings without the automatic runner on second base used in the regular season. Teams keep playing until one leads at the end of an inning.
What Do the Winners Get?
- Commissioner's Trophy: the gold and silver trophy with flags for each MLB team.
- Championship rings: given to players and staff the following season.
- World Series MVP: an award for the standout player of the series.
- Bonus money: players share a pool funded by postseason gate receipts.
When Is the World Series Played?
It usually starts in the last week of October and can stretch into early November if the series goes long or games are rained out. Every game is broadcast nationally in the US on FOX.
Which Team Has Won the Most World Series?
The New York Yankees have won the most, with 27 titles. The St. Louis Cardinals are next among National League teams.
How Often Does the World Series Go Seven Games?
Fairly often. According to MLB.com's count through 2019, 40 World Series went the distance, more than any other length. Sweeps are the least common result.
How Can You Follow the Series as a New Fan?
Learn the starting pitchers for each game, since pitching shapes every matchup. Watch how managers use their bullpens in the late innings, which often decides close games.
Keep a simple tally of the series score. A team needs four wins, so a 3 to 1 lead is a big edge, while a 3 to 3 tie means a winner take all Game 7.
What Are Some Famous World Series Moments?
- Don Larsen's perfect game (1956): still the only perfect game in World Series history.
- Bill Mazeroski's walk off homer (1960): the first World Series to end on a home run in Game 7.
- Kirk Gibson's pinch hit homer (1988): a limping Gibson won Game 1 for the Dodgers.
- Joe Carter's walk off (1993): a series winning home run for Toronto.
- The Cubs end the drought (2016): Chicago won its first title since 1908 in an extra inning Game 7.
Moments like these are why many fans call the World Series the best few weeks of the baseball year.
Why Is It Called the Fall Classic?
The nickname comes from timing. The series is played as autumn arrives, after a regular season of 162 games and several weeks of playoffs, so it caps the whole baseball year.
