What Is the Pro Baseball American League Championship?

Right, let’s set the scene. The American League Championship is ultimately going to determine which team represents the American League in the World Series. This comes after a series of games, where teams compete for playoff positioning and go through to be crowned the league champion. To win the American League, a team needs to have a strong performance throughout the season and be able to perform in high-pressure matches. As a result, the champion is often seen to be a team of elite talent.

Potential Market Outcomes

Of course, the race for which team will be crowned champion is still wide open, with several outcomes possible. As it stands, the main two contenders are the New York Yankees and Seattle Mariners. The simplest scenario is that the favorite (New York Yankees) remains in top form throughout the season.
