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
