In this article
A pennant race is the late-season chase among contending teams to win their league. The pennant itself is the league championship: the American League and National League champions each win one and meet in the World Series. Today, "pennant race" usually covers the whole September scramble for division titles and wild card spots.

Where the term comes from
Champions traditionally received a long, triangular flag, a pennant, to fly over their ballpark the next season. Before divisions existed, the team with the best regular-season record in each league won the pennant outright, so the race for first place was literally a pennant race.
How the pennant is won now
| Era | How a team won the pennant |
|---|---|
| Before 1969 | Best regular-season record in the league |
| 1969 onward | Win the League Championship Series (LCS) |
| Today | Win the LCS, after the Wild Card Series and Division Series |
The regular season now decides who gets into the playoffs and how they're seeded. Fans track each contender's magic number down the stretch.
