ESPN | Jeff Passan: MLB commissioner Rob Manfred, on the heels of a chaotic week in baseball, told MLBPA head Tony Clark that the league could shut down if players can’t better control the spread of COVID-19. A full 20% of the league was on the sidelines last night following positive tests ahead of the Brewers-Cardinals game, and concerns are rising on all sides about the feasibility of pulling this season off just one week in. Of course, Manfred has yet to announce any actual threshold for shutting down, retaining that authority based on his own discretion.
