COVID awaits its next round of pro sports to acquire hosts. Next up: NFL MLB’s season could be in jeopardy if teams and players can’t contain the coronavirus, commissioner Rob Manfred is warning, just a week after opening day. And the shutdown could happen as soon as Monday. According to ESPN’s Jeff Passan, Manfred sent this warning to the players union on Friday — at the conclusion of a week that’s seen the league ravaged by positive tests. The Miami Marlins and Philadelphia Phillies have their seasons on pause after a rash of positive tests. On Friday alone, six teams aren’t playing games because of the wide-ranging effects of players testing positive. The St. Louis Cardinals were the latest team impacted, with two positive tests announced Friday.
