The Division Series (DS) is the quarterfinal round of postseason play in Major League Baseball, featuring the American League Division Series (ALDS) and the National League Division Series (NLDS). Under the current format, the top-two division winners in each league play best-of-five series against the two winners of the Wild Card Series from each league. The winners of the Division Series then advance to the League Championship Series for their respective league.
