The 2020 MLB season has only just kicked off, but a reported coronavirus outbreak among Miami Marlins players and staff has already forced a game to be canceled. 

As ESPN's MLB insider Jeff Passan revealed on Twitter, eight more players and two coaches for the team have tested positive. Over the past few days, the virus has spread throughout the team, bringing the total cases among the Marlins to at least 14. As a result of the infections, the team's opening home game against the Baltimore Orioles on Monday has been canceled. 

The Marlins will remain in Philadelphia as the rest of the staff and players undergo tests. Anyone who has tested positive will be placed in quarantine until they get two negative tests 24 hours apart.

As the Athletic reports, there's currently no specific standards or safety protocols in place regarding the possible shutdown of a team or all teams involved. MLB commissioner Rob Manfred is in charge of making those decisions, leaving any teams with infections to deal with it on their own for the time being.

The team had just played against the Philadelphia Phillies on Sunday, the same day they learned that their starting pitcher and two other players had tested positive. The Philadelphia Inquirer reports that the fate of Monday's game was actually decided by Marlins players themselves in a group text-message. "We knew that this would happen at some point," said Marlins infielder Miguel Rojas, who the team's manager Don Mattingly called the "unofficial team captain." "We came to the ballpark and we were ready to play. That was never our thought that we weren’t going to play."

Sports Grid reporter Craig Mish has indicated the news of the Marlins outbreak has prompted whispers that the 2020 MLB season is "in jeopardy."

Also on Monday morning, the Athletic was told the Yankees-Phillies game is canceled:

It's worth noting that the 2020 MLB season plan stands in stark contrast to the NBA, which didn't allow teams to travel by airplane, interact with the public, or stay in hotels. Instead, the league formed a bubble in Florida in hopes of keeping players and staff safe.
