Having a third catcher makes sense. I’m not wild about Kelly. But what were the other options?
Pitchers Criswell, Guerrero, Winckowski, Crawford, and Fitts are all injured. Harrison has reportedly been learning a new pitch plus a new grip for a second pitch, so he’s not available. I think Moran’s demotion was too recent to call him back up.
That leaves Kelly, Murphy, and Isaiah Campbell.
If they didn’t want another left-handed pitcher, then the choices were Kelly and Campbell…
