The 1916 New York Giants hold the record for the longest winning streak in MLB history at 26 games, but this streak includes a tie, which is not counted toward official statistics. The longest winning streak not including a tie belongs to the 1935 Chicago Cubs at 21 games. The longest winning streak consisting only of playoff games stands at 12 consecutive wins, by the 1927, 1928 and 1932 New York Yankees (swept the World Series all three seasons) and tied by the 1998-99 Yankees.
