The Nationals finally won a postseason series. The Cardinals are vying for their 20th World Series appearance in franchise history.
The only other time these two teams have faced off in the postseason, the Nationals blew a 6-0 third-inning lead and the Cardinals used a four-run ninth inning to end Washington's season.
But that was 2012, and this Nationals team has already overcome major adversity and advanced further into the postseason than any before it. As the teams get ready to decide National League supremacy, let's take a look at the tale of the tape.
