The Cubs-Guardians game was postponed two hours before the scheduled first pitch after weather radar showed a large cell of rain and thunderstorms approaching that was expected to last at least four hours.
The doubleheader will begin at 1:10 p.m. EDT on Sunday, with Edward Cabera (1-0) facing Slade Cecconi (0-1) in the first game and left-handers Shota Imanaga (0-1) and Parker Messick (1-0) set to match up in the nightcap.
