The Padres are uncertain whether Elias Díaz will be available for Tuesday’s Wild Card opener against the Cubs.

Díaz missed Sunday’s game with an oblique issue. While he’s lost playing time, Díaz has continued to serve as Nick Pivetta’s personal catcher since the acquisition of Freddy Fermin, and the Padres would surely prefer not to mess with the pairing at this point. Still, they’re making preparations to be without him, as both Martín Maldonado and Luis Campusano are expected to be in Chicago and available to be activated.
