Major League Baseball didn't test any of its players for COVID-19 before they flew from the Dominican Republic to Miami, according to Jesse Dougherty of The Washington Post.

Many of the players on board the two charter flights later tested positive for the virus. Some of them were asymptomatic at the time of the flight but then tested positive during intake screening with their respective teams, the league confirmed to Dougherty.

Over 160 people - including players and team staff members - boarded the charter flights from the Dominican to Miami on July 1.

"Testing 160 asymptomatic players in the Dominican Republic would have diverted substantial resources away from the Dominican health care system, where the availability of laboratory equipment is scarce, and would have required an exception to the country's criteria for testing, which was not something we were prepared to do," MLB said in a statement.
