The Miami Marlins had trouble filling their roster gaps Monday as they dealt with a coronavirus outbreak. The New York Yankees had an unplanned day off in Philadelphia while the home side underwent COVID-19 testing. The Baltimore Orioles were returning home from Miami without having played their game.

And Washington Nationals manager Dave Martinez summed up the situation in a season that has only just begun.

“I’m going to be honest with you: I’m scared,” said Martinez.

Two major league games scheduled for Monday were suspended after more than a dozen Marlins players and staff tested positive for the coronavirus in an outbreak that left the team stranded in Philadelphia.

The Marlins’ first home game against the Orioles was suspended, as was the duel between the Yankees and the Phillies. The Yankees would have been in the same locker room that the Marlins wore last weekend.

Nine players on the Marlins’ 30 roster, two players from the rotating group and two staff members tested COVID-19 positive, a person familiar with the situation told The Associated Press.
