Dr Anthony Fauci fears the growing outbreak of the coronavirus within the Miami Marlins could threaten the 2020 baseball season.

Fauci said on ABC's Good Morning America program that Major League Baseball still has time to curb the spread of the pandemic.  "This could put it in danger," said Fauci, director of the National Institute of Allergy and Infectious Diseases.

"I don't believe they need to stop, but we just need to follow this and see what happens with other teams on a day-by-day basis."

The Marlins completed a three-game series in Philadelphia on Sunday but opted not to fly back to Miami after more than a dozen cases of COVID-19 were confirmed by positive tests.
