Following the COVID-19 outbreak that's put a halt to the Miami Marlins' season, MLB is reportedly requiring teams to add a COVID-19 protocol compliance officer to its traveling party, according to ESPN's Jeff Passan.
The league is also encouraging players to not leave their team hotels during road trips, and will mandate the use of surgical masks instead of cloth masks during travel.
These new rules were reportedly sent by commissioner Rob Manfred to teams in a memo on Tuesday. They come as a response to the lack of explicit guidelines in the league's original 113-page protocol detailing how teams should handle a coronavirus outbreak.
