Willson Contreras, a three-time All-Star and long-time Chicago Cub, joins the Cardinals, ready, he says, the takeover for Yadier Molina at catcher and possibly hit fifth, where Albert Pujols last did. No pressure, right? How the Cardinals went from exploring trades to committing nearly $100 million to Contreras at catcher is the subject of a brand new Best Podcast in Baseball, featuring St. Louis Post-Dispatch sports columnist Ben Frederickson and baseball writer Derrick Goold. The two discuss the ways Contreras impressed the Cardinals, the first impression he made at his press conference, and how he changes the look of the team, from behind the plate as well as at the plate. There is also a brief tangent on how pitch-framing isn't going anywhere in baseball, even with an automated strike zone. What the signing means for the Cardinals and what the Cardinals must do next is also covered. The Best Podcast in Baseball, sponsored by Closets by Design of St. Louis, is a production of the St. Louis Post-Dispatch, StlToday.com, and Derrick Goold.
