What has allowed Waldschmidt to rise so rapidly through the Diamondbacks' farm system? And what should we expect from him in the majors? Plus, why did the D-backs designated Thomas for assignment instead of optioning him to Triple-A?

We discuss all angles of Friday's roster moves in this live emergency edition of the podcast. Join Jesse Friedman and Jack Sommers on Snakes Territory.
