I am noticing players still spitting on the field, close discussions (between teammates doesn't matter much, I guess, but with umpires too), etc. I highly doubt the virus is being passed on the field, as was the case with Philly, where none of the players tested positive even though the Marlins are riddled with cases.
There had to be some expectation of this built in. You can not freak out over a couple of positive tests or you may as well just cancel the season.
