It seemed unreasonable to Angels players that they’d be asked to subject themselves to those conditions, but MLB’s collective bargaining agreement does not account for preparing to play a game that is postponed after a delay. Rule 12 under Article V, Section C of the agreements states that clubs can reschedule rained-out games “to an open date in the same series, or to an open date at the end of the same series, if: (a) the open date is a road off day for the visiting Club, and (b) the rescheduling does not result in the home team playing more than twenty-four consecutive dates without an open day.”
