The calendar has flipped to October, which means the Major League Baseball playoffs have returned. We’ve already seen some of the drama that comes with the postseason, and it hasn’t disappointed. Let’s take a look back at how we got here.

The AL Wild Card game featured the Astros and Yankees. Houston’s Dallas Keuchel threw six shutout innings and the Astros shut out the Yankees, 3-0, and earned a series with Kansas City.

The NL Wild Card tilt was headlined by Chicago’s Jake Arrieta’s complete-game shutout. The Cubs supported their ace with four runs of support, winning 4-0, sending the storied Cubs team to their first playoff appearance since 2008.

Thus, the division series were set: Houston versus Kansas City, Toronto versus Texas, Chicago versus St. Louis and the New York Mets versus Los Angeles.

At time of publication, the Royals had just come back and tied its series with Houston, 2-2, with a dramatic five-run eighth inning. The deciding Game Five will be tomorrow in Kansas City.

The Blue Jays and Rangers are also tied 2-2. Texas took a commanding 2-0 lead with two road wins, but Toronto won Game Four Monday evening and evened the series.

On the National League side, the Cubs-Cardinals series is knotted at one game apiece at time of publication. Game Three was Monday night.

The Mets tallied three runs against Dodgers ace Clayton Kershaw in Game One of the NLDS Friday night and won 3-1, but Los Angeles took Game Two and brought the series back even at one game apiece. Game Three was Monday night.

October is never short on miracles, and this one has seen its share of them. Will the Royals avenge last year’s World Series loss, or will a National League team win its first championship since 2012? Those are only two possibilities, and as baseball fans have come to expect, the improbable ones aren’t really that improbable.

Let the postseason march on.
