Hall of Fame baseball writer Rick Hummel pinch-hits for Benjamin Hochman as co-host of the Best Podcast in Baseball, and the Cardinals should be so lucky to have a capable, standout replacement on short notice. Jhonny Peralta's hand injury leaves the Cardinals canvassing their own roster for a fill-in at shortstop, and suddenly the lineup doesn't look as deep. Hummel and BPIB co-host Derrick Goold discuss who has the edge at shortstop -- Jedd Gyorko, Aledmys Diaz, or Greg Garcia -- and what the addition of Diaz to the lineup would mean for the Cardinals and their intention to contend. The two longtime baseball writers also discuss Skip Schumaker's retirement, Matt Holliday's turn at first base, and much more, all to the rhythmic sounds of the batting cage. The word "touche" is not uttered. Not once.
