The Philadelphia Phillies have brought all team activities to a screeching halt … after 2 members of the organization tested positive for the coronavirus.

Remember, the Miami Marlins announced a serious COVID-19 outbreak after playing a series in Philly over the weekend … with at least 19 reported cases as of Thursday morning.

The problem — some Marlins players reportedly found out they tested positive for COVID prior to Sunday’s game against the Phillies … but the rest of the team decided to play anyway.

Now, the Phillies are reporting 2 members of the team — zero players — have tested positive … and are taking no chances at letting things get worse.

The team says it’s shut down all team activities “until further notice” … which also leaves the Phillies’ weekend series against the Toronto Blue Jays up in the air.

The Phillies’ series against the Yankees was postponed due to the COVID outbreak … but MLB commish Rob Manfred says the outbreak is “no nightmare.”
