ALCS history: Winners, key stats on the MLB playoff series

MLB altered its playoff structure in 1969 and established the League Championship Series. The LCS is a showdown between the winners of the Division Series to determine which team will represent its respective league - American League and National League - in the World Series. Baseball expanded both the ALCS and NLCS in 1985, from a best-of-five series to a best-of-seven format.

The Toronto Blue Jays defeated the Seattle Mariners in a 7-game series to win the 2025 ALCS. The Blue Jays will make their third World Series appearance versus the Los Angeles Dodgers in 2025.
