Cardinals All-Star shortstop Jhonny Peralta is off on his rehab assignment and set to play at least positions (third, short) as he prepares for his return. In the latest BPIB episode, co-hosts Derrick Goold and Benjamin Hochman, of the St. Louis Post-Dispatch, discuss what Peralta's presence does for the team and how the Cardinals rearrange the infield to make room. Short answer: Pizza is for Producers. As Hochman has to head to cover hockey, StlToday.com columnist Ben Frederickson steps in to discuss his new verb -- "to college" -- and the jolt top prospect Alex Reyes could bring to the Cardinals' pitch staff. The episode is low on puns, high on fractions.
