The postponement will not change the Cardinals’ pitching plans against San Diego for the first game of 2019 at Busch Stadium — Jack Flaherty will get his first career home opener — but it could lead to changes later in the home stand. Dakota Hudson pitched in relief Wednesday night in Pittsburgh, getting his first major-league save in the Cards’ 5-4 victory, and his planned start next week against the Dodgers likely is to be moved back a day.
Major League Baseball sets aside insurance days in the opening weeks of the season so teams can reschedule openers around poor weather and not lose events.
