While the league hasn’t confirmed, multiple reports have said there will be a trade deadline Aug. 31. There will also be a separate COVID-specific inactive list that will include players who test positive or show symptoms of COVID-19, according to ESPN.
The designated hitter will be in the National League after all, as it was part of the health protocols.
In MLB’s news release, commissioner Rob Manfred said the following:
"Major League Baseball is thrilled to announce that the 2020 season is on the horizon. We have provided the Players Association with a schedule to play 60 games and are excited to provide our great fans with Baseball again soon."
