"Need to eat." That's one of the pregame catchphrases -- or mottos, as Cardinals outfielder Tommy Pham says -- that teammates shout during their handshake, clap-slap, high five drills in the dugout. It's a reminder to stay hungry. Or, as Tony La Russa used to say, "Stay greedy." That's the launchpad for a brand new full-length Best Podcast in Baseball, hosted by St. Louis Post-Dispatch baseball writer Derrick Goold. Joined by Ben Frederickson, Post-Dispatch and StlToday.com columnist, and Mark Saxon, a longtime baseball writer and local radio personality, Goold keeps them from lunch long enough to talk about Pham's tone-setting role with the team and all of the roster jolts that have happened -- and the ones ahead. The front office is trying to create an urgency within the clubhouse through transactions, and does that mean it's time for John Mozeliak 3.0. The model was change. Forget the need to eat, the Cardinals need to produce.
