Major League Baseball, which has had at least 12 major-league players and staff members test positive for COVID-19, has decided to immediately shut down all of their spring training facilities in Arizona and Florida, a high-ranking official with direct knowledge of the decision told USA TODAY Sports.
MLB has ordered all of the facilities to undergo a deep clean, and will require all players and staff members to undergo testing before being able to use the facilities again when they open.
The person spoke to USA TODAY Sport on the condition of anonymity since MLB had not released a formal statement.
