The postseason proper is upon us!
Baseball has already played four winner-take-all games in three days. The Dodgers and the Brewers won their divisions in a pair of extra, tie-breaking game number 163s. And then the Cubs and the A's saw their seasons end in the two Wild Card Games.
And now we're onto a round of real, full-length, five-game series. The two National League Division Series start today, and the American League's DSes start tomorrow.
