The Arizona Diamondbacks, Chicago White Sox, Pittsburgh Pirates and Washington Nationals all announced Sunday that two of their players have tested positive for the coronavirus and are in isolation.

The St. Louis Cardinals also announced that another player on their roster tested positive.

The Oakland Athletics are waiting for test results, but two projected members of the team's starting rotation, Mike Fiers and Jesus Luzardo, were not on the field for a second straight day of summer camp because of what Bob Melvin called a "pending'' issue without elaborating.
