Major League Baseball (MLB) is a professional baseball league in North America consisting of 30 teams, 29 in the United States and one in Canada. The Major League Baseball postseason is an elimination tournament held after the conclusion of the Major League Baseball (MLB) regular season. Since 2022, the playoffs for each league – American and National – consist of two best-of-three wild-card playoffs between the worst-seeded division winner & three wild-card teams, two best-of-five Division Series (LDS) featuring the wild-card winners and the winners of each division, and finally the best-of-seven League Championship Series (LCS). The winners of the American League Championship Series (ALCS) and the National League Championship Series (NLCS) play each other in the best-of-seven World Series. The current system allows for up to 53 postseason games and at least 32 games. Wikipedia
