The Washington Nationals' spring facility in West Palm Beach, Florida, is the latest to be turned into a testing area to fight against the coronavirus pandemic.

"Our [spring] complex is being used as a coronavirus testing site until further notice," Mike Rizzo said. "So we're going to shut it down to all players and staff completely while the county and National Guard use it for testing."

At first, spring training facilities were left open during the shutdown, but with more shelter-in-place orders, parking lots and stadiums are being repurposed.

Citizens Bank Park in Philadelphia, Hard Rock Stadium in Miami, FedEx Field in Washington and Raymond James Stadium in Tampa, Florida, are just a few of the others that have been turned into testing centers.
