The Dodgers clinched the season's first postseason spot with a win against the Orioles on Tuesday night in Baltimore, earning their seventh consecutive NL West title.
Those seven straight division wins rank behind only the 1991-2005 Braves and 1998-2006 Yankees for most in the divisional era (since 1969).
