The games between the Pittsburgh Pirates and the Cincinnati Reds which were scheduled for today and tomorrow have been postponed after a Cincinnati Reds player tested positive for COVID-19, it was announced today.
Only one Reds player has tested positive so far, and the Reds and Pirates (who played the Reds yesterday) will presumably quarantine this weekend and undergo daily testing. Given what we know about transmission, it seems unlikely a Pirates player would have contracted COVID-19 from a Reds player from playing yesterday, but the Pirates, I’m sure, will want to err on the side of caution and quarantine while they make sure.
