The speculation has already begun on who might replace Mike Shildt as the next manager of the St. Louis Cardinals. The popular internal candidates appear to be Oliver Marmol and Stubby Clapp, per Jon Morosi of the MLB Network.

St. Louis usually likes to promote from within, and both Marmol and Clapp have surfaced before as candidates for managerial openings. Neither, then, would be a shocking choice, but given the surprising nature of Shildt’s release, anything could be on the table. Without knowing the real nature of the disconnect between Shildt and Cardinals president of baseball ops John Mozeliak, it’s tough to speculate on potential targets.

Players in San Diego, however, are hearing that former Cardinal fan favorite Skip Schumaker might be a candidate for the role, per Kevin Acee of the San Diego Union-Tribune. There would be support from Padres players were Schumaker considered as the Padres’ next manager, notes Acee, but it’s not clear yet what direction president of baseball ops A.J. Preller will lean.
