From Baseball Prospectus, Matthew Trueblood joins Tara and Alex to dive into the greatest rivalry in baseball (sorry not sorry, Yankees/Red Sox). After all, the Cubs and Cardinals are connected by some pretty game-shaking history, including the story at the forefront of baseball minds this week -- Lou Brock. Later, Matt talks about new Cardinal Killer Ian Happ, Tara and Alex work through their feelings about Dylan Carlson, and Matt handles the Chirp of the Week by looking even closer at who Lou Brock played the game.
