The sentence contains the time marker 'yesterday', which refers to a finished action in the past. Therefore the Past Simple form 'checked' is required. 'has checked' (Present Perfect) cannot be used with a finished past time marker. 'was checking' describes an action in progress, but here the action is complete. 'checks' is Present Simple and does not match the past meaning.
