An interesting thing to watch now will be to follow how many players now choose to wear a mask when playing - particularly guys like Freeman who have already had it and been knocked down by it. If Soto tested negative several times in the last week, just where in the *ell did he get it? And if it's still taking 2 days for MLB to get the tests (negative OR positive), just how many teammates might he have just infected?
Freddie in particular would have to think hard about wearing one (as should Catchers) - you'd expect that players have developed at least SOME level of trust in their teammates, and they're not going to get exposed being around them, but how much do you REALLY know about the guy you're holding on? The opposing team's hitter that's standing in the box a foot or two from you?
This probably has as much to do with the city of Pittsburgh not wanting to "double-up" and let the Jays share the stadium - all those Gnats players, coaches, and personnel flew in to NY on the same charter with Soto. Were they wearing masks on the plane? Aaron Judge is now standing at 1B with Thames (and at 2B chatting Turner up a minute later. Were they sitting with Soto on the flight?
