From what I understand, MLB is going to announce the # of players who tested positive for Covid, but cannot announce the specific player names who tested positive without their consent. So who knows what's really going on with the players going on the IL. Could be Covid, could be something else. Like I haven't heard anything about Drury. He went on the IL at the same time as Jonathan Davis, Hector Perez, etc, but the latter have reported to camp, while I don't think I've heard Drury's name at all.
Regardless, as long as numbers are low, and testing issues are fixed, then it's a good sign for now.
