Who is in
The Dodgers clinched the season's first postseason spot on Sept. 10, earning their seventh consecutive NL West title.
Those seven straight division wins rank behind only those of the 1991-2005 Braves and 1998-2006 Yankees for most in the divisional era (since 1969). This time around, the Dodgers tied for the fourth-fewest games needed to clinch a division since 2000 and secured their earliest NL West division crown. The only time in franchise history that they clinched a postseason berth earlier was when they clinched the NL pennant on Sept. 8, 1955.
What's next? The Dodgers have clinched the NL's best record and will play the NL wild-card game winner in the NLDS.

This is Atlanta's 19th division title, which ties the Yankees for most since the beginning of the divisional era in 1969. It has been 15 years since the Braves, Yankees and Dodgers each won their respective divisions (2004).
What's next? An NLDS date with the Cardinals, beginning Thursday in Atlanta, is on tap for the Braves.

The Astros clinched their third consecutive AL West title on Sunday.

The Astros also are the first team to have three straight 100-win seasons in the same decade in which they had three 100-loss seasons (2011-13).
What's next? Houston beat out New York for the AL's top seed and will open ALDS play against either Oakland or Tampa Bay.
