Major League baseball took the first hit to its regular season start on Monday as two games were postponed due to the COVID-19 pandemic.

The Florida Marlins’ July 27 home opener against the Orioles was postponed after at least 14 Marlins players and staff tested positive for the virus, according to reports.

 The Marlins played a weekend series in Philadelphia against the Phillies. The team currently remains in its Philadelphia hotel pending further tests.

Monday night's New York Yankees-Philadelphia Phillies game was also postponed after the league decided not to bring another club into the visiting clubhouse at Citizens Bank Park following the Marlins, according to reports.

The news puts a damper on an otherwise successful start of the season for baseball. Thursday night’s opening game between the Yankees and the Washington Nationals set a record ratings record for ESPN, averaging 4 million viewers.
