The Marlins had more than half of their roster test positive and the Cardinals had a tad under half the roster. They were able to make up the games due to all the double-headers that they played (Marlins played 7 [a tick under 25% of games played] and the Cards played 11 [more than 1/3 of games played]. The schedule was designed and rules were altered in case an outbreak occurred, which it did. They got through it, but I wouldn't necessarily label it as minor issues.
